IS 15935 : 2021 Composite Cylinders for On-Board Storage of Compressed Natural Gas ( CNG ) as a Fuel for Automotive Vehicle - Specification

ICS 23.020;43.060.40                         MED 16

Revised Standard from Last Update.

1 SCOPE

This standard specifies minimum requirements for serially produced light-weight, refillable gas cylinder intended for the on-board storage of high pressure compressed natural gas as a fuel for automotive vehicles to which the cylinders are to be fixed. The service conditions do not cover external loadings which may arise from vehicle collisions, etc. This standard covers metal and non-metal lined composite cylinders of the following types:

a) Type 2 Metal lined hoop wrapped composite cylinders;

b) Type 3 Metal lined full wrapped composite cylinders; and

c) Type 4 Non-metal lined full wrapped composite cylinders.
