Overview
EN ISO 1167-4:2007 - "Thermoplastics pipes, fittings and assemblies for the conveyance of fluids - Determination of the resistance to internal pressure - Part 4: Preparation of assemblies" specifies how to prepare assemblies for hydrostatic pressure testing under ISO 1167-1. The standard covers the preparation of end‑load‑bearing and non‑end‑load‑bearing assemblies made from thermoplastic pipes, fittings, valves and joints (fusion or adhesive) so that their resistance to internal pressure can be assessed consistently and reproducibly.
Key Topics and Requirements
- Scope and principle
- Defines the procedure for assembling test pieces that will be conditioned and subjected to internal hydrostatic pressure testing according to ISO 1167-1.
- Sampling and timing
- Sampling is done as required by the relevant product standard; the interval between production and testing follows material or general specifications.
- Types of assemblies
- Fused assemblies: butt fusion, electrofusion, and multi-component “test tree” configurations; requirements for pipe ends, cleanliness and fusion per manufacturer/product standards.
- Mechanical end-load-bearing assemblies: assembled at ambient temperature unless specified, using manufacturer’s torque/assembly instructions, with torque measurement and no re‑tightening before leakage testing.
- Adhesively bonded assemblies: surface preparation and adhesive application per adhesive manufacturer; specified diametrical clearance, setting time and curing conditions (temperature and humidity).
- Preparation details
- Pipes and components must be cut square, free from impurities, clean, grease‑free and dry.
- Conditioning and bonding often specified at (23 ± 2) °C and (50 ± 5) % RH (when stated); removal of excess adhesive and storage in ventilated area during setting.
- Measurement and tolerance
- Procedures for measuring dimensions and, where necessary, simulating assembly tolerance variations (machining sockets, free pipe length requirements).
Applications and Who Uses It
- Manufacturers of thermoplastic pipes, fittings, and valves - for product development, quality control and type testing.
- Independent test laboratories - to prepare standardised test pieces for hydrostatic pressure testing.
- Certification bodies and regulators - to verify compliance with pressure resistance requirements.
- R&D and materials engineers - to evaluate joint methods (fusion, adhesive, mechanical) and long‑term performance under internal pressure.
- Specifiers and procurement - to ensure test evidence and consistent assembly preparation for acceptance testing.
Related Standards
- ISO 1167-1 (General method for resistance to internal pressure)
- ISO 1167-2, ISO 1167-3 (related parts for pipes and components)
- ISO 11413 / ISO 11414 (electrofusion and butt fusion preparation)
- ISO 3126 (dimensions), EN 1066 / EN 1067 (adhesives)
- ISO 12176‑1 / ISO 12176‑2 (fusion equipment)
This standard is essential when preparing test assemblies for reliable hydrostatic pressure testing of thermoplastic piping systems, ensuring consistent, repeatable results across manufacturers and test houses.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1167-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and
their accessories — Test methods and basic specifications.
