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. Coloration: 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 PA 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 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-H and PP. The largest diameter or the widest part of 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 shall 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 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 given in the delivery programmes of the suppliers. The tolerances on the diameters are given in Table 2 for different diameter ranges. SIST EN 15860:2010

These limit values refer to a reference length of 1 000 mm (see Figure 2). To allow proper measuring, the hollow bar is laid unconstrained on its side on a flat surface so that the weight of the product does not influence the results. The measured value f is the greatest distance between the straight, 1 000 mm long, measuring ruler and the concave point of the hollow bar. See Annex B for the conversion of the deflection as a function of the length.

5.6 Properties 5.6.1 Physical properties The property values below apply only to semi-finished products made from non-modified materials in natural colour (measured on test specimens machined from the semi-finished products). The property values or special requirements for modified materials are to be agreed upon between supplier and customer. The property values of semi-finished products made from thermoplastic materials depend mainly on their thermal history and morphology, and, therefore, on the respective shape (rod, hollow bar, panel/plate) and dimension (diameter or thickness). This makes it very difficult to give limit values that apply to all shapes and dimensions. As a consequence, the values given in the Tables 9 and 10 for density, tensile stress at yield, elongation at break, tensile modulus of elasticity, melting temperature/glass transition temperature and Vicat softening temperature VST/B/50 are not minimum values but guideline values (in italics). They are typical average values from tests on rods of diameter 40 mm to 60 mm, mainly to be used for comparative purposes when selecting a material for a given application. Although these values fall within the normal range of product properties, they are, however, not assured and should not be used to establish material specification limits.
Property values to be used for establishing material specification limits shall be agreed upon between supplier and customer as a function of the shape and dimension(s) concerned. In the case of melt volume flow rate and viscosity number, these are minimum values.

FEN 15860:2010 (E) 24 5.6.2 Dimensional stability after heat treatment The dimensional stability after heat treatment is determined by means of the test described in 6.14.
The relative changes in length, thickness and diameter of semi-finished products made from non-modified materials such as polyamide (PA), polybutylene terephthalate (PBT), polycarbonate (PC), polyetheretherketone (PEEK), polyethylene terephthalate (PET), polyoxymethylene (POM), polystyrene modified polyphenylene ether (PPE+PS) and polyvinylidenfluoride (PVDF) shall not exceed the guideline values given in Table 11 derived from measurements from panels 20 mm high and rods with a diameter of
50 mm to 60 mm.
NOTE There are no values available yet for the other materials listed in Table 1. SIST EN 15860:2010

6 Test methods 6.1 Test conditions Unless otherwise stated in 6.7 to 6.15 or otherwise agreed between supplier and customer, the tests are carried out in a standard atmosphere at (23 ± 2) °C according to EN ISO 291:2008 on dry test specimens. In the case of polyamides, the test specimens shall be dried prior to testing in a vacuum oven at 80 °C until constant weight is achieved followed by storage of at least 16 hours in a desiccator at (23 ± 2) °C. After removal from the desiccator, the tests shall be carried out immediately. 6.2 Sampling size The type and number of semi-finished products belonging to a delivery that have to be tested shall be derived from the respective standards or be agreed between supplier and customer. 6.3 Test specimen preparation 6.3.1 Mechanical properties The test specimens shall be taken as shown in Figures 5, 6 and 7 by means of machining from the semi-finished product in the extrusion direction/longitudinal direction according to the requirements of EN ISO 2818. Deviating procedures, e. g. taking the test specimens perpendicular to instead of parallel with the extrusion direction, shall be agreed between supplier and customer. SIST EN 15860:2010

Figures 5, 6 and 7. During this operation, the material shall not be deformed, overheated or melted. 6.3.3 Melt volume-flow rate, viscosity number, melting temperature/glass transition temperature The test specimens, in the form of granules or chips, shall be taken from the semi-finished products at the positions shown in Figures 5, 6 and 7. Care shall be taken that the material is not overheated or melted during this operation. If moisture-sensitive materials are not tested directly after sampling, the test specimens shall be stored in a desiccator with a drying agent. The testing itself shall be carried out on dry test specimens. 6.3.4 Dimensional stability after heat treatment 6.3.4.1 Rods/hollow bars Three test specimens having a length (l) of (25 ± 0,1) mm shall be tak
