BS IEC 61942:1997 pdf download – Live working一 Gloves and mitts with mechanical protection.
BS IEC 61942 is applicable to insulating gloves and mitts made of plastic or elastomer with appropriate mechanical protection for use without over-gloves. Unless otherwise stated, the use of the term glove only includes gloves and mitts.
The gloves are intended to be used for working live or close to live parts at nominal voltages up to 7 500 V a.c. or 11 250 V d.c.
For other voltages information is not yet available.
1.1 Classes of gloves
Three classes of gloves, differing in electrical characteristics, are provided and are designated class 00, class 0, class 1 (see annex 0).
For other classes such as class 2, class 3 and class 4 additional data will be necessary.
1.2 Categories of gloves
Five categories of gloves, differing in properties related to acid, oil, ozone and a combination of all are provided and designated categories A, H, Z and P respectively, and also extreme low temperature designated as category C.
