Introduction

Hose is connected to a connection point for a rigid or rigid connection between the two points can not place or need Flexing place to Transport all kinds of media. For example. to attract hose and pressure hose, Suction hose, and connected to the mobile device and vibrations between the two parts tube. Hose is used to transport all kinds of media, and generally work under pressure given system. In addition, the hose is also used frequently even those Rigid tube connected at one end or both ends of the local problems. Users often require hoses suppliers, can create some special hoses for their applications.

A hose supplier or manufacturer only if he fully understood the specified operating environment, it may put forward the best proposals. That is to say, in in practice due to lack of understanding may give the wrong advice, resulting in the supply and installation of the hose can not meet the intended purpose. So users and Hose close communication between manufacturers is necessary. The main effect of this standard is to provide information resources for help in making decisions.

1 Scope

This standard provides comprehensive information on the performance of its practical application of rubber and plastic hoses. Comprising a hose used in the performance of the material, the reservoir Precautions should be taken to keep the hose, the hose assembly and installation as well as matters should pay attention to their joints. Also provides a hose during the test when security measures. This standard is scheduled to provide system designers, buyers, assemblers, installers and operators to improve the use of hose and hose assemblies of operational safety.

Note. metal hose is not included in this standard. The circumstances of the metal hose can be found in the following standards. GB/T 18615, GB/T 18616, ISO 8444, ISO 8445, ISO 8446, ISO 8447, ISO 8448, ISO 8449, ISO 8450 and ISO 10380.

In practice, this standard can not cover all situations, so most of its content with examples. And hoped that these examples will on a range of different actual provide sufficient information.
