This standard is intended to be used for rubber and plastic hose assemblies of the types: 1ST, 1SN, 2ST and 2SN according to DIN EN 853, 1TE, 2TE and 3TE according to DIN EN 854, 4SP, 4SH, R13 according to DIN EN 856, R15 according to ISO 3862 and 1SC and 2SC according to DIN EN 857 as well as plastic hoses assemblies of the types R7, R8 and R18 according to ISO 3949, appropriate for temperatures of -40° C up to + 100° C (hose types R13 and R 15 to 120°C) and hose connectors of the light and heavy duty series according to DIN ISO 12151-2 and DIN ISO 12151-3. This standard contains information about the most important criteria for selection and reference of hoses and connectors, the installation and connection dimensions as well as the requirements for the installation of hose assemblies. The comparative presentation of respective hoses types in Table 1 and Table 2 gives designers guidelines for the selection of hoses (nominal diameter and design) and their appropriate connectors, in case the piping of a system has already been determined. Further, guidelines are given in this standard for storage, life cycle and necessary inspections to ensure the full functionality of those assemblies.
