32、hickness of at least 0,2 mm which is uniform over their full cross- section 4 Materials The semi-finished products shall be made of thermoplastic materials (see Table 1). These materials may contain additives such as processing aids, reinforcing agents, fillers, stabilizers or colorants, in which ca
33、se, they are further referred to in this standard as “modified materials“. The nature and the quantity of these additives can influence the mechanical, thermal and electrical properties of the semi-finished products. The choice and the quantities of additives used are left to the discretion of the m

39、her defects which make the product unfit for the intended use. Specific requirements in this respect shall be agreed upon between supplier and customer. The semi-finished products shall be manufactured in such a way that their internal stress level is minimal (see 5.6.2). Natural coloured materials:
40、 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 materials during their manufacture and processing into semi-finished products for the purpose of obtaining another colour. Colora
41、tion: this shall be uniform and shall be agreed upon between supplier and customer. 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 6.4. NOTE Semi-finished products made from P
42、A are dry after manufacture, but absorb moisture during storage. The moisture content in the as-delivered condition is a function of the type of moulding material, the cross-section (plate thickness, rod diameter or hollow bar wall thickness) of the semi-finished product concerned, as well as the ty
43、pe 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-H and PP. The largest diameter or the widest part of
44、the microporosity line(s) shall, however, 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 and/or dielectric strength, they sha
45、ll be agreed upon between supplier and customer. 5.2 Surface appearance Semi-finished products shall essentially have smooth surfaces. Shallow marks, grooves and irregularities resulting from the manufacturing process are allowed provided that the product meets the dimensional requirements according
46、 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 supplier and customer. 5.3 Dimensions and tolerances for rods 5.3.1 Diameter The diameters commonly available are gi
47、ven in the delivery programmes of the suppliers. The tolerances on the diameters are given in Table 2 for different diameter ranges.
