3、8The UK participation in its preparation was entrusted to Technical Committee PEL/78, Tools for live working, which has the responsibility to:The UK technical committee, PEL/78, actively participated in the development of EN 62237 but consistently opposed some of its provisions. In particular, the c
4、ommittee is concerned that the electrical test severely restricts the availability of non-conductive hoses used for live working. It is expected that the tests will be reviewed as part of the maintenance process for EN 62237.The view of the committee is that this standard imposes more onerous test r
5、equirements than have previously been necessary for these applications, e.g. in SAE J343 and SAE J517, with the consequence that users will have a more limited choice of non-conductive hoses without any real increase in safety and those that meet the requirements attract an increase in cost.A list o
