Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. The object of this standard is to qualify thermoplastic tubing for use for brake booster applications.

Applicability. 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 Polyamide (nylon) 12 (PA12) tube.

Remarks.

Type. Two (2) material classifications are defined based on the range of operating temperatures tolerated (see Table 1).
