BS ISO 30021:2013 pdf download.Plastics — Burning behaviour — Intermediate-scale fire- resistance testing of fibre- reinforced polymer composites
This International Standard specifies a method of determining the fire resistance of non-load-bearing separating elements made of fibre reinforced plastics (FRP) when exposed to heating on one lace.
It Is applicable to FRP products for which the end-use application is smaller than the full-scale fire test specimen specified In ISO 834-1. Fire barriers In transportation applications are a common example. since the end-use dimensions of the barrier products are often smaller than those specified in ISO 834-1
This test is, in general, applicable to FRP products which have an essentially tlat surtace and can have stiffening members. This includes sandwich-panel-type structures in which the skins consist of FRP.
CAUTION — The atteiition of all persons concerned with managing and carrying out this lire- resistance test Is drawn to the fact that lire testing Is hazardous and there is a possibility of toxic and/or harmful smoke and gases being evolved during the test. Mechanical and operational hazards can also arise during the construction of the test elements or structures, their testing and disposal of test residues.
It Is essential that an assessment of all potential hazards and risks to health is made and safety precautions are identified and provided. It is also essential that written safety instructions are issued, that appropriate training Is given to relevant personnel and that laboratory personnel ensure that they follow written safety instructions at all times.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 472, ISO 834-12 and ISO 13943 apply.
4 Principle
The fire resistance of a vertically or horizontally oriented intermediate-scale specimen is determined by exposing one of its surfaces to the conditions specified in ISO 834-12. Alternatively, time-temperature curves as specified in EN 1363-2 can he used when their use is relevant to the end-use condition of the product to be tested.
Vertically oriented FRP specimens will be typically 1,5 in high and 1,5 in wide. Horizontally oriented FRP specimens will be typically 1,5 m long and 1,5 m wide. Test speclmen shall be mounted In such a manner as to reflect the end-use condition, Including stiffening members and/or insulation system. If any.
5 Test equipment
5.1 General
The test equipment shall comprise a furnace, restraint and support frames and instrumentation as specified in ISO 834-1 or ISO 834-12, together with a specimen mounting system as specified in 12.
5.2 Specimen mounting frame
The specimen mounting frame shall be made of non-combustible material. i.e. steel or concrete. The structure of the frame shall he strong enough to support the specimen at elevated temperature during the test. Any distortion of the mounting frame shall not affect the specimen.
NOTE Loading of the specimen will not be required in this test.
The linings of the specimen mounting frame, which has direct contact with the test specimen, shall consist of non-combustible materials, e.g. calcium silicate board, having an oven-dry density of (950 ± 100) kg rn-3 and have a minimum thickness of 50 mm. The specimen mounting frame shall be robust enough to support the specimen during the test period in the elevated test temperature condition specified in ISO 834-12.
6 Test specimen
6.1 Number of specimen
For symmetrical constructions or constructions required to resist fire from one specified side only, one specimen shall be tested. For asymmetrical constructions required to resist lire from either side, two specimens shall be tested to permit a lire exposure onto each side of the construction.
6.2 Dimensions
The vertical and horizontal dimensions of the test specimen should each be at least (1000 ± 30) mm.
The construction of the specimen shall represent the end-use condition, and thus, the dimension will be
Increased to that of the end-use condition.
6.3 Structure of specimen
The specimen should include any stiffening members, which are the part of the construction system of the FRP product in end-use.
NOTE ISO 10295-1 covers lire-resistance testing of penetration seals in building elements.
6.4 Insulation of specImen
Thermal insulation is usuallyattached to FRP constructions at the end-use when such a FRP construction is required to have fire-resistance performance. The insulation system, if used in the end-use condition. shall be mounted and fixed to the test specimen as closely as possible to the end-use condition,
Insulation system Is normally attached to the side which has higher fire risk. The specimen should be tested Irma way that tht Insulated side of the specimen is exposed to the test furnace.
The test specimen shall be provided with one vertical joint and/or one horizontal joint in the insulation representative of the end-use condition.BS ISO 30021 pdf download.ISO 30021-2013 pdf download
