scope:
This standard covers the requirements for low pressure tubes for brake boosters.
The thermoplastic tube with an inner layer made of Polyamide (nylon) 6, (PA6) shall not be used in combination with zinc-plated metal fittings (risk of stress cracking).
Direct contact between the thermoplastic tube and materials containing chlorine, as for example adhesive tapes made of Polyvinyl Chloride (PVC) is not allowed, because nascent chlorine resulting from high temperature decomposition may cause cracks in the PA12 tube.
