hen rotating standard test samples, the minimum surface should be facing you, if one end of the package obviously lay particular stress on, then the heavier the face toward you, microwave oven transformer this surface is 5 surface, as the chart:
3. Danger block: material for hardwood or metal, height of 20 ~ 25 mm, width of 150 mm, block length shall package than the time short edge length 200 mm, block the top long edge smoothing, radius for block altitude + / - 0.02 mm.
4. 17th drop test, the test sample impact danger in the geometric center position and danger to the long side parallel to package the short side impact, drop height is packing a distance the height of the base. As below: let me help him solve
