This Standard specifies the requirements for vulcanized compounds and rubber hoses and tubing for use in pressurized and unpressurized cooling circuits containing 1, 2-ethanediol-based anti-freeze in internal combustion engines for private vehicles and commercial vehicles with an unladen weight (as defined in ISO 1176) of 3.5 t or less. For the purposes of this Standard, three different types related to design working temperatures are specified: Type 1: Tubing and hoses for operating temperatures up to 100 degree C Type 2: Tubing and hoses for operating temperatures up to 125 degree C Type 3: Tubing and hoses for operating temperatures up to 150 degree C Two classes for each type related to the operating environment are also specified: Class A: Tubing and hoses for use in positions where they are not likely to be subjected to outside surface contamination by fuel and lubricating oils. Class B: Tubing and hoses for use in positions where they are likely to be subjected to outside surface contamination by fuel and lubricating oils. This Standard covers tubing and hoses whether supplied pre-formed or in straight lengths. It does not cover tubing and hoses made from staple fibre reinforced compounds.
