• exposure conditions: the side(s) to be exposed e.g. ducts (inside/outside);

• dimensions of the component: height, width;

• boundary and support conditions: restraint, free movement, distance between supports;

• variation of constructional details;

• envisaged class(es): i.e. combinations of performance criteria and times.

2. B> Taking into account the direct field of application of test results as specified in the relevant test method and/or the extended application results, the number of tests, standard temperature/time tests and other exposures, and the specimen to be tested shall be deduced.

3. Standard fire tests shall be carried out and for each test the times shall be determined, in elapsed minutes, for which the test specimen continues to satisfy the different aspects of the performance criteria.

4. If more than one test has to be carried out because of the envisaged field of application, the lowest result shall determine the classification for the entire field of application. As the classification is linked to the field of application, results of individual tests may lead to higher ranking for a limited field of application.

5. Classification reports shall be prepared as shown in Annex A. A report may be issued for any combination of performance parameters and times that E)are covered by results of tests and/or by extended application results <51.

No test shall be duplicated for aspects of repeatability and a single test, unless required otherwise by this European Standard, allows the classification of all components in the field of direct application.

If, however, a wider field of application is envisaged, all relevant aspects may not be covered by a single test and additional tests are then required. Also, the influence of different boundary conditions may require evaluation of additional test specimens.

Asymmetrical components may have a different performance depending on the side from which they are tested. In such cases the fire resistance classification shall be based on fire exposure from the side demonstrated as giving the lower fire resistance time. This requires that a test on each side is carried out, except where provided for in the direct field of application.

An asymmetrical component tested from one side only shall be classified for fire attack from that side only.

The number of tests required may further depend on:

• required classifications;

• combination of performance criteria envisaged;

• need to apply more than one thermal attack.

E) deleted text

Products/elements are supplied in a wide variety of sizes, shapes and materials including finishes to satisfy the requirements of the market. It is impractical to test every variation of shape, size or material for each product.

The extent to which a tested product/element may or may not be changed under the field of direct application is given in rules or guidelines which limit the permitted variation away from the test specimen without further evaluation or calculation. The field of direct application clause in each specific test method relates to the common forms of construction for which experience of testing has provided the knowledge that such variations can be safely accepted.

15) The extent to which a tested product or element may be changed under the field of extended application is given in rules in the relevant extended application standards. <51

— Dimensions:

The test specimen shall normally be full size. When the specimen cannot be tested full size, the specimen size shall be in accordance with the specification of the relevant test method. For the application of test results for products/elements with dimensions other than those tested, see the field of direct application clause within E) the appropriate test standard and the field of extended application in the appropriate extended application standard <51.

— Variation of constructional details:

For the application of test results for constructional details other than those tested, see the field of direct application clause within Ei) the appropriate test standard and the field of extended application in the appropriate extended application standard <51.

Different variations of constructional details shall not be included in a single test specimen, unless it can be shown that they will not interfere with the performance of each other.

7.1.3 I5> Field of application

Field of application can be defined using test reports and other relevant data in accordance with the procedures specified in prEN 15725, which e.g. describes the role of extended application in the classification process.

7.2 Classification

The test method for ducts shall be as given in EN 1366-1. The method is applicable to vertical and horizontal four sided ducts with fire exposure from the outside and/or inside, duct A and/or duct B, as a function of the required classification. I5> Extended application shall be carried out as described in the relevant extended application standard and in prEN 15725. <51

^deleted text^J The applicability of results to two or three sided ducts or larger cross section ducts is the subject of extended application.

The design of the test specimen and the number of tests to be carried out shall be derived from a comparison between the envisaged field of application of the classification and the field of application of test results as defined in this European Standard.

The test method provides information on the following:

• test specimen/construction;

• field of direct application of test results;

• guidance on test specimen design.

Aspects influencing the number of tests to be carried out include, for example:

• range of exposure conditions to be covered;

• dimensional variations and orientation;

• pressure conditions.

— Integrity

E> Integrity shall be assessed as the time at which:

1. integrity failure for the duct occurs outside the furnace, using the criteria in 5.1.2;

2. volume flow rate measured in duct A exceeds 15 m³/(m² h) related to 20 °С and related to the internal surface area of the duct inside the furnace as specified in EN 1366-1.

Table 1 gives a summary of the appropriate integrity evaluation.

Table 1 — Integrity evaluation

• Insulation

The performance level used to define insulation shall be the mean temperature rise on the unexposed face, limited to 140 °С above the initial mean temperature, with the maximum temperature rise at any point limited to 180 °С above the initial mean temperature.

• Smoke leakage (if necessary)

Failure of this criterion shall occur if the flow rate in a duct, exposed to fire outside the duct, during the test exceeds 10 m³/(m² x h) related to 20 °С.

7.2.2.4 Classes

The following classes are defined:

El 15 20 30 45 60 90 120 180 240

E 30 60

The classification shall indicate if the performance criteria are satisfied by fire from inside or fire from outside or both, and whether it applies to vertical or horizontal orientations or both. The additions “i -> o”, “o -» i“ or “i o” shall be used respectively together with “ve” and/or “ho” to indicate orientation (vertical and horizontal).

For example, a classification EI30 (ve ho і o) indicates a ventilation duct capable of satisfying 30 min integrity and insulation, from inside to outside and vice-versa in both vertical and horizontal applications.

The classification S shall be added, based on satisfaction of the ambient smoke leakage criterion. This shall be based on a pass/fail test for the leakage. For example, a classification EI30 (ve ho і <-> o) S indicates a duct with the same performance as above but additionally satisfying the leakage criterion (10 m³/(m²h).

Failure of the suspension devices does not constitute failure of the test specimen unless it leads to failure of either E or El.

7.2.3 Fire dampers

The test method for dampers shall be as given in EN 1366-2. E) Extended application shall be carried out as described in the relevant extended application standard and in prEN 15725. (51

The design of the test specimen and the number of tests to be carried out shall be derived from a comparison between the envisaged field of application of the classification and the field of application of test results as E>defined in the test standard and in the relevant extended application standard^]. Full details of the number of tests are given in EN 1366-2:

The test method provides information on the following:

• test specimen/construction;

• field of direct application of test results;

• guidance on test specimen design.

Aspects influencing the number of tests to be carried out include, for example:

• installation of the damper;

• symmetry of the damper;

• direction of flow;

• orientation of the installation.

— Integrity

Integrity shall be assessed during the test as the time at which leakage through the damper after 5 min from the start of the fire test exceeds 360 m³/(m² h), cracks or openings in excess of given dimensions and ignition of a cotton pad and sustained flaming on the non-exposed side at the perimeter of the damper junction with the wall or floor occur. Ignition of the cotton pad shall be disregarded for dampers classified E only.

— Insulation

The performance level used to define insulation shall be the mean temperature rise on the unexposed face, limited to 140 °С above the initial mean temperature, with the maximum temperature rise at any point limited to 180 °С above the initial mean temperature.

— Smoke leakage (if necessary)

For dampers for which the S class is relevant the leakage through the fire damper shall not exceed 200m/(m²h), corrected to 20 °С at ambient temperature prior to the fire test, and shall not exceed 200 m³/(m² h) corrected to 20 °С after the first 5 minutes of the fire test.

The performance criteria, taken from EN 1366-2, are given in Table 2.

Table 2 — Fire test performance criteria for fire resisting dampers

Leakage limits only apply after 5 min from the start of the test.7.2.3.4 Classes

The following classes are defined:

If the leakage rate shall be restricted further, S is added to the classification if the criteria specified in 7.2.3.3 are satisfied.

The classification shall indicate if the performance criteria are satisfied by fire from one side only or from both sides, and whether it applies to vertical or horizontal orientations or both. The additions “і -> о”, “о -> i” or “i o” shall be used respectively together with “ve” and/or “ho” to indicate orientation. For example, a classification El 30 (ve ho і <н>о) indicates a damper capable of satisfying 30 min integrity and insulation, from both sides in both vertical and horizontal applications.

The classification S shall be added, based on satisfaction of the ambient smoke leakage criterion. This shall be based on a pass/fail test for the leakage. For example, a classification El 30 (ve ho і <-> o) S indicates a damper with the same performance as above but additionally satisfying the leakage criterion (10 m³/(m² h).

The functioning of the closing device of fire dampers has also to be assessed, with any damper failing the closing test being ineligible for fire resistance classification.

With respect to the reliability of the closing device, further tests could be necessary and reliability is not covered by this classification.

Failure of the suspension devices does not constitute failure of the test specimen unless it leads to failure of either E or El.Annex A
