BS EN 12115 specifies requirements for two types of hose assemblies (Types D and SD) and four grades based on electrical properties with hoses made of rubber or thermoplastics and hose fittings made of metal designed to convey liquid or gaseous chemical substances, hereinafter termed the “chemicals conveyed”.
Note: This BS EN 12115 does not apply to:
NOTE 1 This document sets out requirements for these hose assemblies to ensure that users are not exposed to danger from fire or explosion and that the environment is protected against contamination or damage.
NOTE 2 Other temperatures and working pressures than those given above can be agreed with the manufacturer, provided that the marking on the hose (see 14.1) states this and the requirements of Table 5 and all the other requirements are met.
NOTE 3 Other diameters than those given in this document can be agreed with the manufacturer.
NOTE 4 This document also provides guidance on the storage of hose assemblies (Clause 15).
NOTE 5 The attention of users is drawn to Annex F concerning the selection of lining material related to the chemical(s) to be conveyed by the hoses and/or hose assemblies.
BS EN 12115 on Rubber and thermoplastics hoses and hose assemblies for liquid or gaseous chemical Specification is applicable to:
Prolonged exposure to gases and hazardous chemicals can corrode metals over time. BS EN 12115 provide guidance to ensure longevity of hoses and helps to reduce defects in the lining. This BS EN 12115 helps to resist the damages which are caused by the weather, also helps in resisting the mechanical damages. BS EN 12115 helps to examine the harmful effects caused on the cover of rubber and thermoplastic hoses and provides a baseline.
This hydrostatic test is conducted to maintain electrical continuity from end-to-end of each hose, and each hose assembly shall be maintained from one fitting to the other. Some tests are conducted for electrical resistance. BS EN 12115 helps in conducting frequent testing of rubber and thermoplastic hoses in order to confirm that all the material, construction and test requirements of this document have been met by the method of manufacture and hose design.
BS EN 12115 provides the acceptable requirements for the satisfactory performance of flexible rubber and thermoplastics hoses. The requirements set by BS EN 12115 helps to resist the chemical, with unspecified reinforcement and linings of different types of synthetic rubbers and thermoplastics.
