Respiratory protective devices for use against chemical, biological, radiological and nuclear (CBRN) agents - Test methods1 Scope This British Standard specifies the test methods in support of the chemical, biological, radiological and nuclear (CBRN) standards BS 8468, Part 1 to Part 7. These tests are conducted in laboratories using specific test agents under specific test conditions and therefore do not specify the performance of the products in actual use.

BS 476-6 is primarily intended for the assessment of the performance of internal wall and ceiling linings

the conditions in which they are produced

The exposure is carried out in a test chamber with a filtered xenon-arc light source simulating solar spectral irradiance according to CIE 85:1989

BS 8313 also covers ducts attached to the outside of buildings

Note1: BS EN 16845-1 does not apply to photocatalytic glass

BS EN 61158-5-8 is part of a series produced to facilitate the interconnection of automation system components

BS 5421-2 on methods of test for polyurethane thread is useful for:

What is BS EN 13727 – Quantitative suspension test for the evaluation of bactericidal activity

Weld appearance — Surface condition

Cutting and machining

BS IEC 62679‑2 specifies the essential ratings and characteristics of EPD modules for the evaluation of optical and electro-optical performances

Mechanical plant cutting
