5.1 sampling standards
Inspectors in accordance with in accordance with the "GB / T 2828.1-2003 / ISO 259-1: 1999 Sampling procedures for inspection of the first part" of incoming for sampling. Sampling level is generally Ⅱ grade, AQL = 1.5. Passing inspection, inspection records really write and sign the acceptance form; unqualified, fill out the "fill unqualified notice", pay determination in charge.
5.2 test content:
5.2.1 The test incoming packaging meets the requirements. Factory logo is clear and complete.
5.2.2 Control of incoming material inspection and acceptance of a single, model, the code is in line with requirements.
5.2.3 Compliance is checked according to the size of the drawing test, the table did not note dimensional tolerances GB / T 1804-92-M class accuracy test:

5.2.4 Surface appearance test: surface if required drawing lines require uniform thickness, surface cleaning, no obvious scratches, bump hurt, spots and dirt defects and other defects; require the film uniform, continuous, complete, and does not allow film layer loose; the surface may not have hanging gray; the surface is not allowed due to the uneven surface of the alloy, re-oxidation caused by long streak after sanding with fine sandpaper.
5.2.6 test film thickness gage allowed no oxide thin film or an oxide film. General requirements for the oxide film of not less than 4μm.
5.2.7 chemical conductive oxide required to measure its conductivity using a multimeter
5.2.8 electrochemical oxidation (General requirements for sulfuric acid anodizing color) test
The film does not allow visual inspection requirements loose powder, hand rub off the end; do not allow parts of the surface with red spots, or the entire surface or local redness; do not allow partial surface oxide film is etched; Do not allow the part surface easy to stick on fingerprints, watermarks, whitish film
