This is common, there are lots of laws that  refer to previous versions of things.

It is not a mistake that the law references a particular version, out of date or not.  This is to ensure that the legally binding conditions are those set by the law makers when the law was written, not some unelected committee at the IET or BSI.

If the legislation had said 'latest version' then every time there is a new book of regs, the law changes, without parliamentary oversight Such 'ambulatory legislation' - you have to love legal English,  - is not normally accepted as it usurps the parliamentary process and would mean that the actions can be criminalised on the whim of a document review.

  Consider also  what might happen in principle if the regs writers were lobbied to change the rules to mandate some new and expensive ADS part only made by one or two vendors - Parliament may want the option to rule that in or out.

Test in the modern way, but read the results against what would have been permitted 2018.
