Coiled Tubing Assemblies for Heavy Duty Air Brake Applications

2013-04-30
WIP
J3041
This SAE Standard establishes the minimum performance and endurance requirements for coiled air brake tubing assemblies used for hookup between tractors, trailers and converter dollies. The Standards SAE J844 and SAE J246 along with J1131 must be consulted to determine the complete performance and endurance requirements of individual components of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation and inspection of these assemblies. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.

Performance Requirements for Nonmetallic Air Brake System Tubing

2014-08-26
WIP
J2547
This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in air brake systems which tubing is different from that described in SAE J844. It is not intended to cover tubing for any portion of the system which operates continuously below - 40 degrees C or above +93 degrees C, above a maximum working gage pressure of 1.0 MPa, or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections, which maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this document, SAE J1131 and SAE J2494-3, to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections which are used in the construction of such assemblies.
