CHAPTER IV

HARMONISED TECHNICAL SPECIFICATIONS

Levels or classes of performance
Article 27
1
The Secretary of State may make regulations, in accordance with Article 60, to establish classes of performance in relation to the essential characteristics of construction products.
2
Where the Secretary of State has established classes of performance in relation to the essential characteristics of construction products, a recognised standardisation body must use those classes in a standard prepared under Article 18A. A responsible TAB must where relevant use those classes in UK Assessment Documents.
Where classes of performance in relation to the essential characteristics of construction products are not established by the Secretary of State, they may be established by a recognised standardisation body in a standard prepared under Article 18A, on the basis of a revised standardisation mandate.
3
When provided for in the relevant standardisation mandate, a recognised standardisation body must establish in a standard prepared under Article 18A threshold levels in relation to essential characteristics and, when appropriate, for intended uses, to be fulfilled by construction products in Great Britain.
4
Where a recognised standardisation body has established classes of performance in a designated standard or a European standardisation body has established such classes in a harmonised standard which is a designated standard, a responsible TAB must use those classes in the UK Assessment Documents where they are relevant for the construction product.
When deemed appropriate, a responsible TAB may, with the agreement of the Secretary of State and after consulting such persons as it considers appropriate, establish in the UK Assessment Document classes of performance and threshold levels in relation to the essential characteristics of a construction product within its intended use as foreseen by the manufacturer.
5
The Secretary of State may make regulations, in accordance with Article 60, to establish conditions under which a construction product is to be deemed to satisfy a certain level or class of performance without testing or without further testing.
Where such conditions are not established by the Secretary of State, they may be established by a recognised standardisation body in a standard prepared under Article 18A, on the basis of a revised standardisation mandate.
6
When the Secretary of State has established classification systems in accordance with paragraph 1, any person may determine the levels or classes of performance to be respected by construction products in relation to their essential characteristics only in accordance with those classification systems.
7
A recognised standardisation body and a responsible TAB must respect the regulatory needs of Great Britain when determining threshold levels or classes of performance.
