ACM cladding

Why has there not been any discussion on the relevancy of the compliance requirements for manufacturers/importers responsibilities under Construction Products Enforcement Regulations 2013 by MCHLG or the construction industry in regards to the cladding?

You mean the Construction Products Regulations.

The cladding had been tested, the question is whether the tests were appropriate / carried out on the correct product / applied correctly. The supplied test results restricted the use of the cladding to the exact configuration that had been tested and required that further tests be carried out if a different configuration was used.

In February 2018, BRE issued a statement revealing that the original tests they had carried out on the cladding system in 2014 were carried out on a test system that was not constructed according to Celotex’s design specification. See https://www.designingbuildings.co.uk/wiki/ACM_cladding_testing_by_BRE#Original_testing

'This article states that ‘The external envelope of a building should not provide a medium for fire spread if it is likely to be a risk to health and safety. The use of combustible materials in the cladding system and extensive cavities may present such a risk in tall buildings.’ As a result, materials with limited combustibility must be used in buildings with storeys more than 18 m above the ground.'

Does this follow? 12.5 says that combustible materials may present a risk. Then follows specific instructions, with 2 alternative routes to compliance. The Linear Route only specifies that insulation materials and filler materials etc should be of limited combustibility. Why then do you say in effect that the AD B2 requires that all materials be of limited combustibility?
