Overview
IEC 60811-507:2012 is part of the IEC 60811 family - "Electric and optical fibre cables - Test methods for non‑metallic materials" - and defines the hot set test procedure for cross‑linked materials. It specifically covers test methods that apply to cross‑linkable compounds used as insulating and sheathing materials in electrical and optical fibre cables. This part cancels and replaces Clause 9 of the withdrawn IEC 60811-2-1:1998 and is intended to be read together with IEC 60811-100:2012 (see Annex A for replacement details). There are no substantive technical changes from the previous edition.
Key topics and requirements
- Scope of test: Procedure for the hot set test applicable to cross‑linkable polymer compounds used in cable insulation and sheathing.
- Mechanical testing focus: Evaluates the behaviour of materials after cross‑linking when exposed to elevated temperature and mechanical stress (i.e., the hot set phenomenon for cross‑linked materials).
- Normative relationships: Intended to be used in conjunction with IEC 60811-100:2012; it replaces the earlier clause in IEC 60811-2-1:1998.
- Standard continuity: No specific technical changes versus the prior edition are reported in the foreword to IEC 60811-100:2012 - the document maintains continuity within the IEC 60811 test series.
- Useable for compliance and testing: Provides an agreed international procedure for laboratories and manufacturers to assess hot set performance of cable materials.
Practical applications
- Quality control and batch acceptance testing of insulating and sheathing compounds for power, control and fibre-optic cables.
- Type testing during product development and material qualification to ensure long‑term mechanical stability after cross‑linking.
- Comparative evaluation of formulations for material suppliers and polymer compounders.
- Reference procedure for test laboratories, certification bodies and procurement specifications where hot‑set behavior of cross‑linked cable materials must be demonstrated.
- Useful in failure analysis and R&D when assessing how cross‑linked materials perform under elevated temperature and tensile load.
