Summary: This standard specifies the requirements for three types and two categories of hoses. These hoses are intended for use in the wet exhaust system of marine engines (where the exhaust gas is mixed with discharged cooling water). The three types are as follows: Type 1: Soft-walled hose, made of oil-resistant materials, reinforced with synthetic fibers; Type 2: Hard-walled hose, made of oil-resistant materials, reinforced with synthetic fibers and embedded with spiral steel wire; Type 3: Hose or non-reinforced hose (soft connection), made of oil-resistant material, with or without reinforcement or outer coating, designed to be used in short lengths to prevent mechanical damage to the connector. The two categories are as follows: Class A, used for diesel engines; Class B, used for gasoline engines and diesel engines with very high exhaust temperatures. This standard does not apply to outboard engines and (or) personal watercraft.
