This International Standard specifies uniform methods for the testing and performance evaluation of metallic tube connections, stud ends for ports and flange connections for use in hydraulic fluid power applications. This International Standard does not apply to the testing of hydraulic quick-action couplings, which is covered by ISO 18869.

Tests outlined in this International Standard are independent of each other and document the method to follow for each test. See the appropriate component International Standard for which tests to conduct and for performance criteria.

For qualification of the connector, the minimum number of samples specified in this International Standard is tested, unless otherwise specified in the relevant connector standard or as agreed upon by the manufacturer and the user.

This document specifies requirements for five types of textile-reinforced hydraulic hose and hose assembly of nominal size from 5 to 100.

They are suitable for use with:

— oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from −40 °C to +100 °C;

— water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from −40 °C to +70 °C;

— water at temperatures ranging from 0 °C to +70 °C.

This document does not include requirements for end fittings. It is limited to requirements for hoses and hose assemblies.

NOTE It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.

This part of ISO 12176 specifies an encoding system for data of components, assembly methods and jointing operations for polyethylene (PE) piping systems for gas, water and other industrial uses. These data may be used in a traceability system and/or used to perform the fusion of components by using equipment as specified in ISO 12176-1 and in ISO 12176-2.

This encoding system is elaborated under the, ISO/IEC 16022, ISO/IEC 18004, ISO/IEC 24778[1] to which it refer for establish code type (e.g.: QR code) and its coding characteristics.

Examples of data to be encoded are: fusion cycle(s), traceability of manufactured product, other manufacturer information that may also be given on web-sites (1) eg.: web site, voluntary certificate(s) of quality, approval(s), etc.

NOTE 1 E.g. readable also by applications on mobile devices.

This standard specifies the export of data (type, format and sequence) from a data retrieval system.

Provisions of this standard are applicable to polyethylene components conform to ISO 4427-2[2], ISO 4427-3[3], ISO 4437-2[4], ISO 4437-3[5], ISO 4437-4[6] and ISO 15494,[7] and it may be applicable also to other components used in PE systems.

NOTE 2 ISO 13950 and ISO 12176-4, which partly are covering the fields of application of this Part 5 of the ISO 12176, may be used in parallel.

This International Standard establishes general principles regarding the procedure used in the construction and quality assessment of butt fusion jointing of polyethylene (PE) piping system components specified in accordance with relevant ISO standards. These components are installed in accordance with the relevant codes of practice, national regulations or industry guidance. Specifically, this International Standard specifies three butt fusion jointing procedures for PE pipes and fittings. These are:

 single low-pressure fusion jointing procedure;

 dual low-pressure fusion jointing procedure;

 single high-pressure fusion jointing procedure.

This International Standard takes into consideration the materials and components used, the fusion jointing procedure and equipment and the quality assessment of the completed joint. It may be applied in conjunction with appropriate national regulations and standards.

NOTE 1 The references for these procedures are given in the bibliography[1][2][3][4]. Single low-pressure fusion jointing procedure is derived from multiple procedures and agreed by experts, given in the bibliography [1][2].

NOTE 2 The three procedures detailed in this standard are based on those most commonly used. It is not the intention that one or more of these procedures should be used to replace well established and verified industry based procedures.

This part of prEN 13476, together with prEN 13476-1, specifies the definitions and requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are intended to be used for non-pressure underground drainage and sewerage systems.

This part is applicable to pipes and fittings with smooth internal and external surfaces, designated as Type A.

It specifies test methods and test parameters as well as requirements.

This part is applicable to:

a) structured-wall pipes and fittings, which are intended to be used buried underground outside the building structure; reflected in the marking of products by "U";

b) structured-wall pipes and fittings, which are intended to be used buried underground both outside (application area code "U") and within the building structure (application area code "D"); reflected in the marking of products by "UD".

This part is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.

This part covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes, application classes, and tolerance classes and gives recommendations concerning colours.

NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This part of ISO 21809 specifies requirements for field joint coating of seamless or welded steel pipes for buried and submerged sections of pipeline transportation systems used in the petroleum, petrochemical and natural gas industries as defined in ISO 13623. This part of ISO 21809 specifies the qualification, application and testing of the corrosion protection coatings applied to steel surfaces left bare after the joining of pipes and fittings (components) by welding.

This part of ISO 21809 defines and codifies in Table 1 the different types of field joint coatings for pipelines.

This part of ISO 21809 does not address requirements for additional mechanical protection, for thermal insulation or for joint infills of concrete weight-coated pipes.

NOTE Field joints of pipes and fittings coated in accordance with this part of ISO 21809 are considered suitable for further protection by means of cathodic protection.
