It does, actually, assuming you want the legislation to work.Wittering on about whether there should first be a standard for socket covers in place, or whether the minister and/or officials are competent to make a regulation serves no honourable purpose.
Because that's the way that legislation has to work, there really is no viable alternative.
If you want something new in addition to the existing legislation which can deal with products not fit for purpose then you have to have it defined before you can enforce it.
If you want it compulsory for socket covers etc to conform to the dimensional requirements of BS 1363, then who is going to test products for compliance?
What tests will they do?
You could have something with the right sized pins but too flexible, so who is going to define what degree of flexibility is acceptable in each direction/plane?
How would the tests for that be developed?
Who would design the test rigs required for the tests?
How would the existing BS 1363 standard be altered to incorporate these devices?
And ones which are not socket covers but items of test equipment?
Or any plug-in devices such as adapters, power supplies, air fresheners, night lights, ethernet adapters.....?
What would be marked on something which was just a socket cover, since it clearly could not be BS 1363, as not all of the tests could be done?
Just saying to makers "it's got to be dimensionally correct" (a) isn't enough (flexibility for instance, heat resistance would be another) and (b) doesn't put into place any framework in which makers can have their assertion of compliance verified and by which products can be labelled so that a law prohibiting non-compliant products has something to refer to, so that Trading Standards bodies can identify non-compliant ones and buyers can identify compliant ones.
You are either going to need a whole new standard, or several new sections in BS 1363, BS 1363-6, -7 etc.
If you say "We urge the government to extend regulation to include all plug in devices intended for use in BS1363 sockets." it's no use not being able to answer, with sufficient detail and precision that a law could be drafted, the question "OK, how?"
