25、ard specifies the terminology, requirements and test methods for metal coil, strip, and flat sheets and factory made pieces intended for fully supported applications in roofing and wall cladding or lining. It does not apply to products manufactured on site. This European Standard covers fully-suppor
26、ted aluminium, copper, lead, steel, stainless steel and zinc products with or without coatings, e.g. metallic, organic, inorganic or multi-layer (see Annex A). This European Standard also includes rules for marking, labelling and evaluation of conformity. Requirements concerning acoustical and insul
27、ation properties are not considered in this European Standard. This European Standard does not include calculation or design requirements with regards to the works, installation techniques or the performance of the installed products. 2 Normative references The following documents, in whole or in pa
