41、cks, foreign matter and other defects which make the product unfit for the intended use. Specific requirements in this respect shall be agreed upon between manufacturer and customer.The semi-finished products shall be manufactured in such a way that their internal stress level is minimal (see 5.6.2)
42、.Natural coloured materials: slight variations in hue originating from raw materials and/or manufacturing process are allowed.Natural colour means that no additives (colorants) are added to the raw material during their manufacture and processing into semi-finished products for the purpose of obtain
43、ing another colour.Colorations: These shall be agreed upon between manufacturer and customer. The coloration shall be uniform. Slight variations in hue originating from raw materials and/or manufacturing process are allowed.The testing of the as-delivered condition shall be performed according to 6.
44、4.NOTE Semi-finished products made from PA are dry after manufacture, but absorb moisture during storage. The moisture content in the as-delivered condition depends on the type of moulding material, the cross-section (plate thickness, rod diameter or hollow bar wall thickness) of the semi-finished p
45、roducts, as well as the type and period of storage.Semi-finished products made from POM, PEEK and PP are permitted to have light patches in the centre of the cross-section.Microporosity in the centre of the cross-section may occur in semi-finished products made from POM and PP. The largest diameter
46、or the widest part of the microporosity line(s) shall not exceed 4 %. The procedure for the determination and measurement of microporosity is described in Annex A.When semi-finished products made from POM and PP are subject to specific requirements, e.g. pressure tightness (microporosity) and/or die
47、lectric strength, they shall be agreed upon between manufacturer and customer.7BS EN 15860:2018EN 15860:2018 (E)5.2 Surface appearanceSemi-finished products shall essentially have smooth surfaces. Shallow marks, grooves and irregularities resulting from the manufacturing process are allowed provided
48、 that the product meets the dimensional requirements according to 5.3, 5.4 and 5.5.Testing of the surface appearance shall be performed according to 6.5.Specific requirements with respect to the surface appearance are to be agreed upon between manufacturer and customer.5.3 Dimensions and tolerances
