Guidance is available in G-085.

This issue of the standard supersedes 1-085 A1.

Purpose

The purpose of this standard is to define the requirements for the fire safety of materials, in terms of flammability, smoke emission and toxic fume emission, installed on the London Underground (LU) network:

The business objective of this standard is to ensure that the risk to which the public and employees are exposed is controlled to a level that is as low as reasonably practicable.
