Anatomy of a standard 1-085/section 12 compliant fitting

  1. Low smoke/zero halogen cables– all LUL Standard 1-085 (regulation governing standards for sub-surface rail equipment, also known as section 12) fittings have to use low smoke and zero halogen emitting cabling, to prevent air becoming toxic in the case of a fire.
  2. High IP65 rating– they also have to have a high IP rating to prevent ingress of particulates commonly found in the sub-surface rail environment (brake dust particulates for example).
  3. Glass diffuser– diffusers must be glass and at least 6mm thick, again to prevent harm to passengers and staff during a fire.
