Full title and description

Insulating materials - Industrial, rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section, based on thermosetting resins for electrical purposes — Part 2: Methods of test. This document specifies test methods used to assess the dimensional, mechanical, electrical and other properties (water absorption, density, etc.) of industrial rigid moulded laminated tubes and rods made from thermosetting resins for electrical applications.

Abstract

IEC 62011-2:2004 defines standardized test procedures for industrial rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section manufactured from thermosetting resins (phenolic, epoxy binders with paper, cotton or glass reinforcements). The standard covers conditioning, dimensional checks, mechanical strength tests specific to rods and tubes, electrical tests including insulation resistance after water immersion, and additional measurements such as water absorption and density. It is intended to support consistent quality assessment and material specification in design, manufacture and procurement of electrical insulating components.

Scope

This part of IEC 62011 specifies test methods applicable to industrial, rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section intended for electrical purposes and based on thermosetting resins. Tests and procedures in the scope include conditioning of specimens, measurement of external and internal dimensions and wall thickness, assessment of departure from straightness, mechanical tests (flexural strength perpendicular to laminations for rods; axial compressive strength for tubes), electrical tests (general provisions and insulation resistance after immersion in water) and other determinations such as water absorption and density. The standard applies to materials conforming to the IEC 62011 series and is intended to be used alongside the relevant material specification parts of the series.

Key topics and requirements

• Conditioning of test specimens (preparation and environmental conditioning before testing).
• Dimensional checks: external and internal dimensions, wall thickness and tolerances, departure from straightness.
• Mechanical tests: flexural strength perpendicular to laminations (for rods) and axial compressive strength (for tubes).
• Electrical tests: general test procedures and insulation resistance measurement after immersion in water.
• Other tests: determination of water absorption and material density.
• Test reporting: standardised presentation of results to support material specification, quality control and comparison between batches/suppliers.

Typical use and users

IEC 62011-2 is typically used by manufacturers of laminated thermosetting insulating tubes and rods, independent and in-house test laboratories, quality assurance and inspection teams, product engineers and designers of electrical equipment, procurement/specification engineers, and conformity assessment bodies. It supports material acceptance testing, supplier verification, product development and compliance checking where consistent test methods are required.
