Full title and description

ISO 10147:2011 — Pipes and fittings made of crosslinked polyethylene (PE‑X) — Estimation of the degree of crosslinking by determination of the gel content. This International Standard specifies a solvent‑extraction method to estimate the degree of crosslinking (gel content) in PE‑X pipes and fittings for use in conformity assessment and quality control.

Abstract

ISO 10147:2011 provides a test method based on solvent extraction to determine the gel content of crosslinked polyethylene (PE‑X) pipe and fitting materials; the measured gel content is used as an estimate of the degree of crosslinking. The procedure covers sample preparation, extraction and calculation/reporting of gel content.

Scope

This standard specifies a method for the assessment of the degree of crosslinking in crosslinked polyethylene (PE‑X) pipes and fittings by determination of the gel content by solvent extraction. It is intended for use in production testing, type testing and quality control where gel content is an appropriate indicator of crosslinking. The method estimates crosslinking but does not itself define product acceptance criteria.

Key topics and requirements

• Definition and purpose: gel content as an indicator of the degree of crosslinking in PE‑X materials.
• Sample preparation requirements for pipe and fitting specimens prior to extraction.
• Solvent‑extraction procedure to remove soluble polymer fraction and determine insoluble (gel) fraction.
• Calculation and reporting of gel content (% insoluble material) and associated test conditions.
• Applicability: method specifically for PE‑X pipes and fittings; it is a comparative/estimation method, not a performance specification.

These topics summarize the method elements described in the standard’s abstract and scope.

Typical use and users

Primary users are manufacturers of PE‑X pipes and fittings, independent testing laboratories, product certification bodies and quality assurance teams who need to estimate the degree of crosslinking for process control, material verification and conformity assessment. Standards committees and regulators may also reference the method when specifying test procedures.

Related standards

ISO 10147:2011 supersedes ISO 10147:2004 (and its amendment ISO 10147:2004/Amd 1:2008). Related test methods and product standards for plastics pipes and fittings (PE‑X) include other ISO, EN and national standards covering materials, mechanical testing and long‑term performance of PE‑X piping systems; users should consult product‑specific and regional standards for full conformity requirements.

FAQ

Q: What is this standard?

A: ISO 10147:2011 is an International Standard that specifies a solvent‑extraction test method to estimate the degree of crosslinking in crosslinked polyethylene (PE‑X) pipes and fittings by determining gel content.

Q: What does it cover?

A: It covers sample preparation, solvent extraction to remove soluble fractions, calculation of gel (insoluble) content and reporting of results; it is an estimation method for crosslinking in PE‑X materials, not a product performance specification.

Q: Who typically uses it?

A: Manufacturers, testing laboratories, certification bodies, QA/QC personnel, standards committees and regulators involved with PE‑X pipe and fitting materials.

Q: Is it current or superseded?

A: ISO 10147:2011 is the current published edition (edition 3, 2011). ISO’s record shows the document was reviewed and confirmed (remained current) during its periodic review in 2022. Users should check the national standards body or ISO catalogue for any subsequent revisions after 2022.

Q: Is it part of a series?

A: It is a single‑method standard specific to gel‑content estimation for PE‑X; it relates to a family of standards addressing plastics pipes and fittings (ICS 23.040.20 and 23.040.45) and to earlier editions/amendments (ISO 10147:2004 and ISO 10147:2004/Amd 1:2008).

Q: What are the key keywords?

A: PE‑X, crosslinked polyethylene, gel content, solvent extraction, degree of crosslinking, pipes, fittings, ISO 10147.
