ICS 43.040.60; 83.160                          TED 7

Revised Standard from Last Update.

1. Scope

This standard specifies the dimensions, materials, tests and acceptance standards for valves and valve accessories for tyre tubes as supplied for application with inner tubes, and valves for use with automotive vehicles including two wheeled vehicles, off-the-road vehicles and animal drawn vehicles. This standard gives those dimensions of commonly used valves which are important for fitment and interchangeability. Although the tests for valve cores have been included, the dimensions for valve core chambers have not been included since the same is covered in IS/ISO 20562 : 2004 ‘Tyre Valves - ISO Core Chambers No. 1, No. 2 and No. 3’. Valve caps are also not covered in this standard since these are covered by IS 9453 : 2014 ‘Specification for valve caps for tyre tube valves for automotive vehicles.’
