Full title and description

Live working — Electrical insulating matting. International standard that specifies requirements, tests and classification for elastomer-based insulating matting used as floor coverings to provide electrical protection for workers performing live working on electrical installations.

Abstract

IEC 61111:2009 is the second edition of the standard and replaces the 1992 edition and its 2002 amendment. It contains a technical revision of requirements and test provisions (including revised slip-resistance tests, dielectric proof/withstand test provisions and a new normative annex on classification of defects) and provides guidance for selection and use of insulating matting for a.c. and d.c. applications. The text has been adopted as EN 61111:2009 in the European system.

General information

• Status: Current international standard (adopted as EN 61111:2009; national adoptions in multiple countries).
• Publication date: 7 April 2009 (IEC publication date).
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 13.260 (Protection against electric shock); 29.240.20; 29.260.99 (Other electrical equipment for working in special conditions).
• Edition / version: 2nd edition (2009).
• Number of pages: 66 pages (IEC webstore listing for IEC 61111:2009).

Scope

Applies to electrical insulating matting manufactured from elastomer and intended as floor coverings to protect personnel working on electrical installations. The standard covers classification by electrical class (classes 0–4, with suffixes for special categories), physical and dimensional requirements, mechanical, climatic and environmental tests, dielectric tests (proof and withstanding), slip resistance, marking, packaging and instructions for use. It also includes normative and informative annexes giving guidance on class selection, temperature ranges and defect classification.

Key topics and requirements

• Classification of matting by electrical class (class 0, 1, 2, 3, 4 and category C for extremely low temperature).
• Material and construction: matting shall be manufactured of elastomer and be slip resistant on both sides; inserts must not impair dielectric properties.
• Dimensional and workmanship requirements (minimum dimensions, tolerances and thicknesses for different classes).
• Mechanical, climatic and environmental tests (folding at low temperature, abrasion, acid and oil resistance, and related conditioning times).
• Dielectric requirements: specified proof and withstand tests including proof testing practices and test electrode specifications.
• Slip-resistance test procedure and surface finish requirements.
• Marking, packaging and instructions for safe use, storage and inspection (including provisions for batch/proof testing and defect evaluation).

Typical use and users

Used by manufacturers of insulating matting, testing laboratories, electrical utilities, contractors and maintenance teams working on live electrical equipment, procurement/specification engineers, safety officers and regulators to select, test and verify insulating matting for worker protection during live working. The standard is frequently referenced in national adoptions and procurement specifications.

Related standards

References and related documents include IEC 61318 (evaluation of defects and related guidance used in the standard), the earlier CLC/TS 61111:2006 (superseded), and the European adoption EN 61111:2009. Work to revise/adopt the text under IEC/EN procedures has been tracked in subsequent national confirmation and maintenance records.

FAQ

Q: What is this standard?

A: IEC 61111:2009 is an international standard titled "Live working — Electrical insulating matting" that specifies requirements and test methods for elastomer insulating matting used to protect workers from electric shock when working live.

Q: What does it cover?

A: It covers classification, material and physical requirements, dimensional tolerances, mechanical and climatic tests, dielectric proof and withstand testing, slip resistance, marking, packaging and instructions for use, plus annex guidance and defect classification.

Q: Who typically uses it?

A: Manufacturers, test houses, electrical utilities, contractors, safety officers, procurement/specification teams and standards bodies use the standard to design, test, specify and approve insulating matting for live working environments.

Q: Is it current or superseded?

A: IEC 61111:2009 is the 2nd edition (published April 7, 2009) and is listed as a current IEC publication; it has been adopted as EN 61111:2009. National records show confirmation activity and work items for later maintenance or revision, so users should verify national adoption status for compliance updates.
