ISO 13363:2016规定了三种类型和两类软管的要求。软管拟用于船用发动机湿式排气系统（排气与冷却水排放混合）。它不适用于舷外发动机/个人水上航行器。 这三种类型如下: -类型1:软壁软管，由耐油材料制成，带有合成纤维增强材料； -类型2:硬壁软管，由耐油材料制成，带有嵌入螺旋线的合成纤维增强材料； -类型3:软管或管（柔性接头），由耐油材料制成，带或不带加强件或盖，用于在接头受到机械损伤保护的位置短距离使用。 这两个类别如下: -A类:用于柴油发动机； -B类:用于汽油发动机和排气温度非常高的柴油发动机。

ISO 13363:2016 specifies requirements for three types and two classes of hose. The hoses are intended for use in marine-engine wet-exhaust systems (where the exhaust gases are mixed with the discharge of cooling water). It does not apply to outboard motor/personal water craft. The three types are the following: - type 1: a softwall hose, made of oil-resistant material, with a synthetic-fabric reinforcement; - type 2: a hardwall hose, made of oil-resistant material, with a synthetic-fabric reinforcement with a helical wire embedded in it; - type 3: a hose or tube (flexible connector), made of oil-resistant material, with or without a reinforcement or cover, intended for use in short lengths in locations where the connector is protected from mechanical damage. The two classes are the following: - class A: intended for diesel engines; - class B: intended for petrol engines and for diesel engines with a very high exhaust temperature.
