标准范围

ISO 11424:2017规定了内燃机上各种空气和真空系统中使用的橡胶软管和管的要求。本文件不包括卡车和拖车中用于直接动力制动器驱动的软管，也不包括用于乘客舱内进气口和管道的软管。最高温度软管通常用于涡轮增压器应用。所有软管和管道在40°C以下仍可使用。注:尽管通常使用真空一词，但实际上，该应用是一种降低空气压力的应用，用于驱动或监测各种发动机系统部件。由于特殊的安装和应用，管道或软管携带的空气可能是清洁的，没有污染物，但也可能含有油、燃料及其蒸汽作为污染物。

ISO 11424:2017 specifies requirements for rubber hoses and tubing for use in the various air and vacuum systems found on internal combustion engines. This document does not cover hoses used for direct power-brake actuation in trucks and trailers, nor for air intakes and ducting within the passenger compartment. The highest-temperature hoses are generally used for turbocharger applications. All hoses and tubing remain serviceable down to？40°C.NOTE Although the term vacuum is generally used, in reality the application is one of reduced air pressure used for the purposes of actuation or monitoring of the various engine-system components. The air carried by the tubing or hoses may be clean and free of contaminants but may also contain oil, fuel and their vapours as contamination, due to the particular installation and application.
