标准编号：ISO 11424:2023

中文名称：内燃机的空气与真空系统用橡胶软管和管件 规范

英文名称：Rubber hoses and tubing for air and vacuum systems for internal-combustion engines — Specification

发布日期：2023-07

标准范围

本文件规定了用于内燃机上各种空气和真空系统的橡胶软管和管道的要求。本文件不包括用于卡车和拖车直接动力制动驱动的软管，也不包括用于乘客舱内的进气口和管道的软管。最高温度的软管通常用于涡轮增压器应用。所有软管和管道都可以使用，直到？40？°C。笔记？虽然通常使用术语真空，但实际上应用是用于致动或监测各种发动机系统部件的目的的降低的空气压力之一。由管道或软管携带的空气可以是清洁的并且没有污染物，但是由于特定的安装和应用，也可以包含油、燃料及其蒸汽作为污染物。

This document 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 can be clean and free of contaminants but can also contain oil, fuel and their vapours as contamination, due to the particular installation and application.
