1 Scope
This international standard is applicable to insulating sleeves for the protection of workers fromaccidental contact with live electrical conductors, apparatus or circuits.
1.1Five classes of sleeve, differing in electrical characteristics,are provided and designatedas: Class o,Class 1,Class 2,Class 3 and Class 4.
1.2 Five categories of sleeve with different properties are provided, related to the following:resistance to acid, resistance to oil, resistance to ozone,combined resistance to oil and ozone,and also resistance to extreme low temperature.These are designated as Categories A,H, Z,s and C respectively.
1.3Two styles of sleeve，differing in configuration，are provided and designated as straighttaper and curved elbow.
2 Definitions
For the purpose of this standard, the terms hereafter have the following meanings:
elastomer
a generic term that includes rubbers, latex and elastomeric compounds that may be natural orsynthetic, or a mixture, or a combination of both
type test
a test of one or more devices made to a certain design to show that the design meets certainspecifications
[IEV 151-04-15]”
routine test
a test to which each individual device is subjected during or after manufacture to ascertainwhether it complies with certain criteria
[IEV 151-04-16]
sampling test
a test on a number of devices taken at random from a batch[lEV 151-04-17]
acceptance test

flashover
an arc by-passing an insulating body[IEV 121-03-14]
nominal voltage
a suitable approximate value of voltage used to designate or identify a system[IEV 601-01-21]
composition
The sleeves shall be manufactured of elastomers and produced by a seamless process.The holes provided in sleeves, for the purposes of strap or harness attachments, shall havenon-metallic reinforced edges,and shall be nominally 8 mm in diameter.
4classification
The sleeves covered under this standard shall be designated as follows:- by class as Class o, Class 1,Class 2,Class 3 and Class 4;
– by special properties, by the addition of a suffix as shown in table l;- by style as described in 4.1.1.
