NOTE Test results are only valid for the tested method of mounting, together with any direct or extended field of application that may be applicable.

Tests shall be performed starting with the smoke control damper in the open position. It will be driven closed at the start of the test to meet the two minute requirement.

Temperature and integrity measurements shall be carried out in various parts of the test construction during the test. The impermeability of the smoke control damper system shall be measured by direct flow measurements whilst maintaining a constant pressure differential across the closed smoke control damper of 300 Pa. The leakage rate of dampers requiring an S classification shall be measured at ambient temperature.

It may be necessary to test smoke control dampers not mounted directly within the centre of the supporting construction, both inside and outside the supporting construction for it to be universally acceptable for that method of installation.

A further smoke control damper sample shall be subjected to a furnace based fire test to prove operation and maintenance of opening. The smoke control damper is attached (directly or remotely via a section of ducting), in/to a supporting construction using a method described in the test standard (EN 1366-10) in a manner generally representative of practice. Smoke control dampers may be situated within the construction of the wall/floor, attached to the face of the wall/floor, or mounted remotely from it via a section of fire resistant ducting.

Tests shall be performed starting with the smoke control damper in the open position. It will be cycled and observed (EN 1366-10).

Equipment and method as fully described in EN 1366-10, the largest size to be manufactured shall be subjected to the selected cycling test, followed by the fire resistance test (EN 1366-10). Units shall be fire tested in the plane of proposed installation, noting the direct field of application of fire test results.

NOTE For information purposes only, the unit may be ambient leakage tested prior to the fire test.

Equipment and method as fully described in EN 1366-10, the largest size to be manufactured shall be subjected to the selected cycling test, followed by the ambient leakage test, followed by the fire resistance test (see EN 1366-10). Units need to be fire tested in the plane of proposed installation, noting the direct field of application of fire test results.

In addition, the smallest size to be manufactured shall be subjected to an ambient leakage test (see EN 1751) to provide the information necessary to gain this classification.

The response delay is proven, provided that the smoke control dampers achieve the opening and closing requirements defined in EN 1366-10:2010, 6.2.

A second smoke control damper sample shall be subjected to a standby temperature test to prove the longevity of any electrical items. This shall be as described in EN 1366-10.

The equipment and test method referenced in Annex A and EN 60068-2-52 shall be used.

The equipment and test method referenced in EN 1366-10.

The following performance and rating test methods for dampers and valves specified in EN 1751 and EN ISO 5135 shall be used:

1. Damper blade leakage

Leakage past a closed damper or valve may be classified using the data published in EN 1751. Classes then increase 1 to 4 with class 4 being the most leak tight.

2. Damper casing leakage

Duct damper casings shall be constructed to meet the minimum leakage limits specified for the ductwork system to which they are installed. Dampers shall have casing leakage classes to meet EN 1751. Ductwork leakage classifications C and D will be met by dampers having casing leakage classification C according to EN 1751.

NOTE There is no class D classification for damper casings in EN 1751, but due to the small surface area of a damper as part of the whole ductwork system Class C is adequate.

In order to apply the calculation sometimes required to confirm ductwork leakage, the reference casing area shall be taken as the perimeter size of the damper multiplied by the equivalent length of one metre (e.g. an 800 mm x 400 mm duct damper shall have a surface area for casing leakage performance calculated as ((2 x 0,8) m + (2 x o,4) m ) x 1 m = 2,4m²).

3. Damper flow rate/pressure resistance characteristics

Damper flow rate/pressure resistance characteristics shall be measured according to the method prescribed, and presented in the manner described, in EN 1751.

4. Operational torque testing

Operational torque shall be measured according to the method prescribed, and presented in the manner described, in EN 1751.

5. Thermal transmittance testing

Thermal transfer shall be measured according to the method prescribed, and presented in the manner described in EN 1751.

6. Regenerated sound power levels

Regenerated sound power levels shall be measured according to the method prescribed, and presented in the manner described in EN ISO 5135.

5. Evaluation of conformity

   1. General

The compliance of a smoke control damper with the requirements of this European Standard shall be demonstrated by:

— initial type testing,

— factory production control by the manufacturer, including product assessment.

For smoke control dampers produced as one-offs, pre-production smoke control dampers (e.g. prototypes) and smoke control dampers produced in very low quantities, 6.4 shall apply.

Initial type testing (ITT) shall be performed to demonstrate compliance of smoke control dampers with this European Standard.

All essential characteristics for which the manufacturer declares performances are subject to initial type testing. Tests shall be carried out in accordance with Clause 5. No smoke control damper needs to be re­tested for the sake of proving repeatability, but more than one smoke control damper shall be required to be tested to cover different applications.

Because the objective of the general testing procedures is to establish the ability of the smoke control damper to achieve the product design and performance requirements and classification in its operational position (i.e. end use conditions), and to continue to act as a barrier/opening for a designated period of time, the complete product (i.e. including motors and fixings) to be installed shall be tested.

In the case of modification of the smoke control damper or of the method of production (where these may affect the stated performance characteristics), the initial type testing shall also be performed. All characteristics given in Clause 4, which may be changed by the modification, shall be subject to this initial type testing, except those tests described in 6.2.3.

Tests previously performed in accordance with the provisions of this standard may be taken into account for the ITT purpose providing that the tests:

• were equivalent or more rigorous;

• were carried out by a third party in the frame of a national/voluntary certification scheme;

• were carried out on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question.

Products may be grouped into families where the results for one or more characteristics from any one product in the family are representative for all other products within that family.

NOTE 1 Products may be in different families for different characteristics.

NOTE 2 Reference to the test methods standards should be made to allow the selection of a suitable representative sample.

In addition, Type Tests or Initial Type Testing shall be performed for all characteristics included in the standard for which the manufacturer declares performances:

• at the beginning of the production of a new or modified smoke control damper design, the raw material or supplier of the components;

• at the beginning of a new or modified method of production (where this may affect the stated properties); or

• they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the smoke control damper design, in the raw material or in the supplier of the components, or in the production process (subject to the definition of a family), which would affect significantly one or more of the characteristics.

Where kit components are used whose characteristics have already been determined, by the component manufacturer, on the basis of compliance with other technical specifications, these characteristics need not be reassessed The specifications of these components shall be documented, as shall the inspection scheme for ensuring their compliance.

Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the CE marking, although this does not replace the responsibility of the smoke control damper designer to ensure that the smoke control damper as a whole is correctly designed and its components have the necessary performance values to meet the design.

Test samples of smoke control dampers shall be representative of the current production.

If the technical documentation (see 8.1) of the test samples does not give a sufficient basis for later compliance checks, a reference test sample (identified and marked) shall remain available for this purpose.

All initial type testing and its results shall be documented in a test report.

The manufacturer shall establish, document and maintain an FPC system in a form of permanent internal control of production to ensure that the smoke control damper placed on the market continuously complies with the ITT sample, for which compliance with this European Standard has been verified and expressed by the smoke control damper’s stated performance characteristics.

If the manufacturer has the product designed, manufactured, assembled, packed, processed and labelled by subcontracting, FPC of the original manufacturer may be taken into account. However, where subcontracting takes place, the manufacturer shall retain the overall control of the products and ensure that he receives all the information that is necessary to fulfil his responsibilities according to this European Standard. The manufacturer, who subcontracts all of his activities, may in no circumstances pass his responsibilities on to a subcontractor.

All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of conformity evaluation and enable the achievement of the required smoke control damper characteristics and the effective operation of the production control system to be checked.

Factory production control, therefore, brings together operational techniques and all measures allowing maintenance and control of the conformity of the product with this European Standard. Its implementation may be achieved by controls and tests on measuring equipment, raw materials and constituents, processes, machines and manufacturing equipment and finished products, including material properties in products, and by making use of the results thus obtained.

Manufacturers having an FPC system which complies with EN ISO 9001 and which addresses the requirements of this harmonised standard are recognised as satisfying the FPC requirements of the Council Directive 89/106/EEC.

Where a manufacturer operates different production lines or units in the same factory, or production lines or units in different factories, and these are covered by a single, overall FPC system, the manufacturer still has to keep control records for each separate production line or unit (and this shall be made a requirement of the technical specification). However, when performing FPC inspections, although the product specific aspects always need to be evaluated, the Notified Body does not have to repeat systematically the assessment of “general” FPC provisions which apply to all lines/units.

The FPC system shall:

• address this European Standard, and

• ensure that the products placed on the market conform with the stated performance characteristics.

This involves:

1. the preparation of documented procedures and instructions relating to factory production control operations;

2. the effective implementation of these procedures and instructions;

3. the recording of these operations and their results;

4. the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-conformity.

Production control operations include some or all of the following operations:

1. the specification and verification of raw materials and constituents;

2. the controls and tests to be carried out during manufacture according to a frequency laid down in the prescribed test plan;

3. the verifications and tests to be carried out on finished products according to a frequency in accordance with Annex C and adapted to the product and its conditions of manufacture.

Depending on the specific case, it may be necessary to carry out i) the operations referred to under b) and c), ii) only the operations under b) or iii) only those under c).

The operations under b) centre as much on the intermediate states of the product as on manufacturing machines and their adjustment, and equipment etc. These controls and tests and their frequency are chosen based on product type and composition, the manufacturing process and its complexity, the sensitivity of product features to variations in manufacturing parameters etc.

With regard to operations under c), where there is no control of finished products at the time that they are placed on the market, the manufacturer shall ensure that packaging, and reasonable conditions of handling and storage, do not damage products and that the product remains in conformity with the technical specification.

The appropriate calibrations shall be carried out on defined measuring and test instruments.

6.3.3.2 Verification and tests

The manufacturer shall have or have available the installations, equipment and personnel which enable him to carry out the necessary verifications and tests. He may, as may his agent, meet this requirement by concluding a sub-contracting agreement with one or more organisations or persons having the necessary skills and equipment.

The manufacturer shall calibrate or verify and maintain the control, measuring or test equipment in good operating condition, whether or not it belongs to him, with a view to demonstrating conformity of the product with its technical specification.

The equipment shall be used in conformity with the specification or the test reference system to which the specification refers.

If necessary, monitoring shall be carried out of the conformity of intermediate states of the product and at the main stages of its production.

NOTE This monitoring of conformity focuses where necessary on the product throughout the process of manufacture, so that only products having passed the scheduled intermediate controls and tests are dispatched.

Tests shall be in accordance with the test plan in Annex C.

The manufacturer should establish and maintain records which provide evidence that the product has been tested. These records should show clearly whether the product has satisfied the defined acceptance criteria. Where the product fails to satisfy the acceptance measures, the provisions for non-conforming products should apply.

If control or test results show that the product does not meet the requirements, for example if the statistical variation of test results exceeds the limits allowed by the technical specification (see Annex C), the necessary corrective action shall immediately be taken.

Products or batches not conforming shall be isolated and properly identified. Once the fault has been corrected, the test or verification in question shall be repeated.

If products have been delivered before the results are available, a procedure and record should be maintained for notifying customers.

The results of factory production controls shall be properly recorded in the manufacturer's register. The product description, date of manufacture, test method adopted, test results and acceptance criteria shall be entered in the register under the signature of the person responsible for control who carried out the verification.

With regard to any control result not meeting the requirements of the technical specification, the corrective measures taken to rectify the situation (e.g. a further test carried out, modification of manufacturing process, throwing away or putting right of product) shall be indicated in the register.

It is the manufacturer's, or his agent's, responsibility to keep full records of individual products or product batches, including their related manufacturing details and characteristics, and to keep records of to whom these products or batches were first sold. Individual products or batches of products and the related manufacturing details shall be completely identifiable and retraceable. In certain cases, for example for bulk products, a rigorous traceability is not possible. The expression of the requirement in the relevant technical specifications should be realistically adapted keeping in view traceability as complete as possible.

• the FPC-documentation, and

• the factory.

In the initial assessment of the factory and FPC, the following shall be verified:

1. that all resources necessary for the achievement of the product characteristics required by this European Standard are (see 6.3.4.1) available, and

2. that the FPC-procedures in accordance with the FPC-documentation are (see 6.3.4.1) implemented and followed in practice, and

3. that the product complies (see 6.3.4.1) with the initial type testing samples, for which compliance with this European Standard has been verified.

In the case of modification of the smoke control damper, the method of production or the FPC system (where these may affect the smoke control damper’s declared performance characteristics), a re-assessment of the factory and of the FPC system shall be performed for those aspects (including the relevant ITT), which may be affected by the modification.

All assessments and their results shall be documented in a report.

6.4 One-off smoke control dampers, pre-production smoke control dampers (e.g. prototypes) and smoke control dampers produced in very low quantities

Smoke control dampers produced as a one-off, prototypes assessed before full production is established, and smoke control dampers produced in very low quantities (less than 30 per year) shall be assessed as follows.

For initial type assessment, the provisions of 6.2 shall apply, with the following exceptions:

• all smoke control dampers presented for test shall be supported by full design documentation,

• a sampling process is not required as no “production” batch will be available.

The FPC system of one-off smoke control dampers and those produced in very low quantities shall ensure that raw materials and/or components are sufficient for their production. The provisions of 6.3 shall apply, only where appropriate. The records allowing traceability of the smoke control dampers shall be maintained.

For prototypes, where the intention is to move to series production, the initial inspection of the factory and FPC shall be carried out before the production is already running and/or before the FPC is already in practice. The following shall be assessed:

• the FPC-documentation; and

• the factory.

In the initial assessment of the factory and FPC it shall be verified:

1. that all resources necessary for the achievement of smoke control dampers characteristics required by this European Standard will be available, and

2. that the FPC-procedures in accordance with the FPC-documentation will be implemented and followed in practice, and

3. that procedures are in place to demonstrate that the factory production processes can produce a smoke control damper complying with the requirements of this European Standard and that smoke control dampers will be the same as the initial type testing samples, for which compliance with this European Standard has been verified.
