IEC 60811-504:2012 gives the procedure for performing bending tests at low temperature on extruded insulations and sheaths. IEC 60811-504:2012 cancels and replaces 8.1 and 8.2 of IEC 60811-1-4:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100: 2012.   This publication is to be read in conjunction with IEC 60811-100:2012.

Overview

EN 60811-504:2012 (identical to IEC 60811-504:2012) defines a standardized procedure for bending tests at low temperature on extruded insulations and sheaths used in electric and optical fibre cables. It is part of the IEC 60811 series of test methods for non-metallic materials and is intended to be read in conjunction with EN/IEC 60811-100 (general provisions). The part replaces selected clauses of earlier editions without technical change and provides reproducible requirements for cold-bend performance assessment of cable materials.

Key topics and technical requirements

• Scope and applicability
  • Applies to extruded insulation and sheathing materials for cables (electric and optical fibre).
  • Intended primarily for insulated conductors and cables with dimensions up to 12.5 mm (external or major axis), unless a cable standard requires larger sizes.
• Sampling and test pieces
  • Each core is represented by two test samples after removal of coverings where applicable.
• Apparatus
  • Test uses a revolving mandrel and guiding devices (cold-bend apparatus); alternative single-mandrel equipment of equivalent performance is permitted.
  • Apparatus and specimens are placed in a low-temperature cabinet during conditioning and test.
• Temperature conditioning and timing
  • Tests are carried out at the temperature specified in the relevant cable standard.
  • Standard cooling period: not less than 16 hours (includes time to cool the apparatus). If apparatus is pre-cooled, minimums of 4 hours at test temperature, or 1 hour after mounting pre-cooled specimens, are permitted.
• Procedure and evaluation
  • The mandrel is rotated according to specified conditions (see normative table in the standard); results are evaluated against criteria in the relevant cable standard.
• Limitations
  • For larger cables, IEC 60811-505 (elongation at low temperature) may be used or equipment adapted per the cable standard.

Applications and users

EN 60811-504:2012 is essential for:

• Cable manufacturers validating low-temperature flexibility and brittleness resistance of insulation and sheathing compounds.
• Independent testing laboratories performing standardized cold-bend tests for product qualification and compliance.
• Material suppliers developing formulations for cold environments (energy, telecom, ship, offshore).
• Standards committees and quality engineers specifying cable performance in cold climates.

Related standards

• EN/IEC 60811-100:2012 - General requirements for test methods for non-metallic cable materials.
• EN/IEC 60811-505 - Elongation at low temperature for insulations and sheaths (complementary mechanical test).

Keywords: EN 60811-504:2012, IEC 60811-504, bending tests at low temperature, insulation and sheaths, cable testing, non-metallic materials, cold-bend test.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects
