Full title and description

BS EN IEC 62677-2:2018 — Heat shrinkable low and medium voltage moulded shapes. Part 2: Methods of test. This document specifies test methods for heat‑shrinkable moulded shapes used for insulation, environmental sealing, mechanical protection and strain relief in low and medium voltage cable accessories and connector/cable terminations.

Abstract

This standard (the British adoption of EN IEC 62677-2:2018) defines the procedures, conditions and acceptance criteria for laboratory tests used to assess the physical, thermal and environmental performance of heat‑shrinkable low and medium voltage moulded shapes. The tests are intended to control material and product quality; electrical performance in assembled accessories is verified by related assembly standards. The document is equivalent to IEC 62677-2:2017 and is intended for manufacturers, test houses and specifiers of cable accessories and insulating components.

Scope

Specifies methods of test for heat‑shrinkable low and medium voltage moulded shapes in a range of configurations and materials used for insulation, environmental sealing, mechanical protection and strain relief for connector/cable terminations and multi‑way transitions. The tests are aimed at controlling the quality of the moulded shapes (mechanical, thermal and environmental properties). Electrical performance of assembled accessories is confirmed in the appropriate assembly standards (for example EN 50393, HD 629.1 and IEC 60502-4).

Key topics and requirements

• Definition of specimens and sampling for test.
• Dimensional and shrinkage measurements (recovery and shrink characteristics after heating).
• Mechanical tests: tensile strength, elongation at break, hardness and compression set.
• Thermal tests: thermal ageing (endurance), heat resistance and required oven/conditioning procedures.
• Environmental tests: water immersion, humidity, salt spray and resistance to environmental degradation.
• Flammability and tracking resistance where applicable to the material/objectives.
• Reference to relevant conditioning, test atmospheres and pre‑test procedures (aligned with IEC test practice standards).
• Procedures for reporting results and criteria to demonstrate conformity of materials or moulded shapes.

Typical use and users

Used by manufacturers of heat‑shrinkable moulded shapes and materials, third‑party testing laboratories, cable accessory designers, utilities and specification writers who require established laboratory methods to verify material and product performance. Also used by purchasing and quality departments for incoming inspection and by national standards bodies for adoption and harmonization.

Q: What does it cover?

A: The standard covers specimen preparation, conditioning and a range of mechanical, thermal and environmental test methods (shrinkage, tensile/elongation, hardness, thermal ageing, water resistance, etc.) used to assess the performance and quality of heat‑shrinkable moulded shapes.

Q: Who typically uses it?

A: Manufacturers, test laboratories, utilities, cable accessory designers, procurement and quality assurance teams, and standards committees involved with insulating materials and cable accessories.

Q: Is it current or superseded?
