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 Б) defined in the test standard and in the relevant part of prEN 15254 EI-

The test methods provide information on the following:

• test specimen;

• field of direct application of test results;

• guidance on test specimen design especially for testing glazed elements.

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

• the sides to be tested.

• facades and external walls shall be tested from both sides or from the inside or outside only.

Constructional variations required such as elements with and/or without un-insulated portions, e.g. glazing: additional tests shall be undertaken using separate test specimens as a function of the envisaged field of application including the nature of the supporting construction of glazing.

The assessment of integrity shall be made on the basis of the following three aspects:

• cracks or opening in excess of given dimensions;

• ignition of a cotton pad;

• sustained flaming on the unexposed side.

E) Classification for integrity shall be according to whether or not the element is also classified for insulation. Where an element is classified both for integrity and insulation, the value of integrity is that determined by whichever of the three aspects fails first. Where an element is classified without an insulation classification, the value of integrity is that determined by the time to failure of only the cracks/openings or sustained flaming aspects, whichever fails first.

The performance level, used to define thermal 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 C° above the initial mean temperature.

The test standards specify how both for uniform and non-uniform elements the mean temperature shall be determined.

For elements which incorporate discrete areas of different thermal insulation, compliance with the thermal insulation criteria shall be determined separately for each area.

When testing in accordance with EN 1364-3 and EN 1364-4 the results for the thermal insulation and integrity shall be presented separately for the external face, the internal face and the linear joint seals, as specified in the test standard.

E) Classification for radiation shall be given by the time for which the maximum value of radiation, measured as specified in the test standard, does not exceed 15 kW/m².

The following classes are defined:

When the elements are tested from both sides, with standard temperature/time curve from inside and external fire exposure curve from outside, the lowest time determines the classification.

Test and classification may also be performed from one side only. Whichever test(s) is/are performed and classification(s) determined, the classes are identified by:

“i->o” when classification is envisaged from inside to outside and

“o->i” when classification is envisaged from outside to inside.

“o«->i” when classification is envisaged from inside to outside and from outside to inside.

For example, a classification El 60 (i->o) indicates a wall which is capable of providing 60 min integrity and thermal insulation performance from the inside only, whereas a classification El 60 (o«->i) indicates a wall with the ability to provide the same level of performance from both inside and outside.

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 shall include for example:

1. the sides to be tested: ceilings may be tested from below or from above only or from both sides in consecutive tests depending upon the intended classification;

2. the orientation of the ceiling:

if the longitudinal and transversal direction are constructed differently, and the most onerous condition cannot be identified, two separate tests shall be carried out with the components arranged both parallel and perpendicular to the longitudinal axis;

3. constructional variations required, such as support conditions, and the presence or absence of cables and pipes, giving additional load to the ceiling during fire;

4. light fittings which can create openings in the ceiling.

When tested from below, the assessment of integrity shall be made on the basis of the following three aspects:

1. cracks or opening in excess of given dimensions;

2. ignition of a cotton pad;

3. sustained flaming on the unexposed side.

Classification of integrity shall be according to whether or not the element is also classified for insulation. Where an element is classified both for integrity E and thermal insulation I, the integrity value shall be that determined by whichever of the three criteria fails first. Where an element is classified E but without an I classification, the integrity value shall be defined as the time to failure of only the cracks/openings or sustained flaming criteria, whichever fails first.

When tested from above, gap gauges shall not be used for the evaluation of the occurrence of cracks or openings in excess of given dimensions. The ceiling shall be deemed to fail the criterion for integrity when visible openings or flames are observed along the unexposed surface of the ceiling. Such openings or deterioration shall be judged as:

4. being when a component of the ceiling has fallen down or where an edge of a component has left its supporting profile element;

5. the formation of gaps visually assessed as being equivalent to those measured by the gap gauges.

The performance level, used to define thermal 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.

The following classes are defined:

El 15, El 30, El 45, El 60, El 90, El 120, El 180, El 240.

Where classification is expressed from above, the addition of “a-»b” (“a” referring to above and ”b” to below the membrane) shall be used; similarly the addition of “a<-b” shall be used for classification from below, and “a<->b” shall be used for classification from both above and below.

For example, a classification El 30 (a«-b) indicates a ceiling membrane which is capable of providing 30 min integrity and thermal insulation performance from the underside only, whereas a classification

El 30 (a<->b) indicates a ceiling membrane with the ability to provide the same level of performance from both the underside and from above the ceiling.
