The oxygen index test is the most economical, repeatable, and precise test to evaluate the reaction to fire behavior of the material, widely used for plastic, textile, and building material industries.

This fire test has been developed for use by those responsible for the selection of construction products which, whilst not completely inert, produce only a very limited amount of heat and flame when exposed to temperatures of approximately 750 °C.

This guideline is only used to guide testing personnel in installing SBI specimens. Users need to comply with the requirements specified in the standard when using this guide.

EN 13823 Single burning item testing can be considered as a pillar of the European grading system for building products. B-D class (combined with test results from EN ISO 11925-2), A2 class (combined with test results from EN ISO 1716 or EN ISO 1182), and sometimes A1 class all require test results.

EN 13823:2020 Single burning item testing can be considered as a pillar of the European grading system for building products. B-D classl (combined with test results from EN ISO 11925-2), A2 class (combined with test results from EN ISO 1716 or EN ISO 1182), and sometimes A1 class all require test results.

This Part of BS 476 specifies a method of test for measuring the lateral spread of flame along the surface of a specimen of a product orientated in the vertical position under opposed flow conditions, and a classification system based on the rate and extent of the spread of flame. It provides data suitable for comparing the end-use performances of essentially flat materials, composites or assemblies, which are used primarily as the exposed surfaces of walls or ceilings.

Dynamic graphics make it easier for you to understand these testing methods.

Test method for EN 13501-1 A1: Test Method: 1. EN ISO 1182: Reaction to fire tests for products — Non combustibility test 2. EN ISO 1716: Reaction to fire tests for products — Determination of the gross heat of combustion (calorific value)

The old standard EN 45545-2:2013+A1:2015 divides materials into 26 categories, R1-R26, based on their ultimate use. The latest standard EN 45545-2:2020 divides materials into 28 categories, R1-R28, based on their ultimate use. The R1-R26 categories are basically consistent with the old standards, with the addition of R27 light diffusers and display screen covers, and R28 floor composite materials (including floor substrates and floor coverings).
