Typical examples of cross-sections are as shown in Figures 1 and 2. 4.2 Marking and examples The product marking is expressed in the order of product name, this part number, material code, size specification (product code x length x cross-section height), and product category (non-type I is not marked). Examples of markings are as follows. 4.5 Microstructure Under the observation by metallographic microscope, the glass fibers of the polyamide profiles shall be evenly distributed, the typical distribution is shown in Figure 4.There shall be no defects such as air bubbles (as shown in Figure A.3) and obvious inclusions (as shown in Figure A.4). 4.7 Dimensional deviation 4.9 Appearance quality The appearance of the polyamide profile shall be smooth, flat and uniform in color, the surface shall not have any appearance defects that affect the use.5 Test methods5.1 Test environment The laboratory temperature is 23 °C ± 2 °C and the relative humidity is 50% ± 10%. 5.2 Specimen pretreatment All specimens are placed in a common drying oven at 140 °C ± 2 °C for 6 h and then taken out and placed in a desiccator at 23 °C ± 2 °C for at least 2 h. 5.5 Ash 5.6 Microstructure The microstructure is tested in accordance with the method as specified in Appendix B. 5.7 Fracture morphology The fracture that has been transversely stretched at room temperature is placed under a scanning electron microscope equipped with a camera. The magnification shall be selected at 100× ~ 500×, a representative field of view is selected for photo recording. 5.9 Performance 5.9.1 Density The density test is carried out in accordance with the impregnation method as specified in GB/T 1033.1-2008. 5.10 Appearance quality Under natural scattered light, visually inspect it with normal vision. 5.11 Aluminum alloy profile composite adaptability The composite adaptability of aluminum alloy profiles is tested in accordance with the method as specified in Appendix F.6 Inspection rules6.1 Inspection and acceptance 6.1.1 The product shall be inspected by the supplier to ensure that the product quality complies with the provisions of this part or the order form (or contract), and it shall fill in the quality certificate. 6.2 Batching Products shall be submitted for acceptance in batches. Each batch consists of the polyamide profiles of the same equipment, the same component, and the same size specifications for every 24 h during continuous production; it is also considered as a batch during interrupted production for less than 24 h. 6.3 Inspection classification Product inspection is divided into exit-factory inspection and regular inspection. 6.4 Inspection items and process assurance item 6.6.2 If the ash of any specimen is unqualified, the batch is judged to be unqualified. 6.6.3 If the microstructure of any specimen is unqualified, the batch is judged to be unqualified. 6.6.7 When the DSC melting peak temperature of any specimen is unqualified, another double number of specimens shall be taken from the batch for repeated test. If the repeated test results are all qualified, the batch of products is judged to be qualified. If the DSC melting peak temperature of any one specimen is still unqualified in the repeated test results, the batch is judged to be unqualified. 6.6.20 When the composite suitability of the aluminum alloy profile of any one group of specimens is unqualified, another double number of specimens shall be taken from the batch for repeated test.7 Marking, packaging, transportation, storage andquality certificate 7.1 Marking 7.2 Packaging The rolled strip polyamide profile should be packaged into a roll of 300 m ~ 1000 m, the straight strip shaped polyamide profile should be packaged into a bundle of 50 ~ 100 pieces. 7.3 Transportation and storage 7.3.1 In transportation and storage, it shall avoid contact with acids, alkalis, salts and organic solvents. Avoid sun exposure, rain, impact or extrusion. 7.4 Quality certificate Each batch of polyamide profile shall be accompanied by a product quality certificate, indicating the information below.8 Order (or contract) contentOrder forms (or contracts) for ordering the polyamide profiles listed in this part shall include the following. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
