19、(E) 4 Introduction In this European Standard, the performance of the product has been defined as far as possible in terms of a number of type tests. The performance of a building element made with these products depends not only on the properties of the product as it is required by this European sta
20、ndard, but also on the design and quality of the fabrication of the building element and on the design, construction and behaviour of the part of the building concerned in relation to the environment and conditions of use. The lead sheet supplied shall be specified and used according to the National
21、 Code of Practice, depending on service conditions such as exposure to direct sunlight and the area of the piece of lead to be fixed.
