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.

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 International Standard specifies the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use, with repeated opening and closure. It does not specify the ability of valves to withstand adverse conditions, in particular those of chemically aggressive fluid media and/or environments, or excessive fluid velocities and cavitation.

NOTE For what concern the chemical aggression of the materials, a classification table is reported in ISO TR 10358[1].

This International Standard includes values of the parameters necessary for the proper performance of the endurance test, with the reservation that parameters may be different in particular product standards (see 5.1).

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.

This document specifies six test methods for the determination of the initial circumferential tensile wall strength per unit of length of glass-reinforced thermosetting plastics (GRP) pipes.

NOTE Another commonly used term for "circumferential tensile strength" is "hoop tensile strength" and the two expressions can be used interchangeably.

The burst test (method A) is suitable for all types and sizes of pipes. It is considered the reference method. However, all the methods in document have equal validity. If correlation of any of the methods B to F can be established by a comparative test programme, then that method can be considered as the reference method.

The split disc test (method B) might not be suitable for pipes with helically wound reinforcing layers.

The strip test (method C), the modified strip test (method D) and the restrained strip test (method E) are suitable for pipes with a nominal size of DN 500 and greater.

The notched plate test (method F) is primarily intended for use with helically wound pipes of nominal size greater than DN 500 with a winding angle other than approximately 90°.

Results from one method are not necessarily equal to the results derived from any of the alternative methods.

If required, the initial circumferential tensile modulus can be determined by method A.

This document, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of water supply networks which transport water intended for human consumption, including raw water intake pipelines.

It applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline. It applies to the use of various thermosetting resin systems, in combination with compatible fibrous carrier materials, reinforcement, and other process-related plastics components (see 5.1).

It does not include requirements or test methods for resistance to cyclic loading or the pressure rating of CIPP liners where passing through bends, which are outside the scope of this document.

It is applicable to cured-in-place pipe lining systems intended to be used at a service temperature of up to 25 °C.

NOTE For applications operating at service temperatures greater than 25 °C guidance on re-rating factors can be supplied by the system supplier.
