【正文】 ations used for optical microscope observation is described in Appendix II.建議使用倍率光學(xué)顯微鏡進(jìn)行檢驗(yàn)，見附錄二描述。The examination and records are applied to the critical area of individual contact. The definition of critical area of contacts is decribed in Appendix I.檢查和記錄，是適用于臨界區(qū)域的個(gè)別接觸。電鍍條片的接觸，也可用于及最低數(shù)額的接觸是 6 倍的數(shù)量每引腳連接器。 Optical gauge 光學(xué)測量儀This optical gauge is imaged with a Hirox KH3000 stereo microscope.這個(gè)光學(xué)測量儀與 Hirox KH3000 立體顯微鏡很相似。2. ANALYSIS OF TESTED SAMPLES 樣品分析The dryed and cooled samples are analyzed using optical (stereo microscope/metallurgical microscope) microscopes or scanning electron microscope (SEM). Images of the tested connector springs are imaged and the images are saved. These images are pared with respective gauge and are given a score according to the gauge scale.風(fēng)干/冷卻后的樣品使用光學(xué)顯微鏡或掃描電子顯微鏡進(jìn)行分析。Figure 5. The tested samples are removed from the chamber and put on a glass plate圖 5 將被試驗(yàn)的樣品從試驗(yàn)區(qū)移出放置在玻璃器皿中。In the figure the tested samples are hanging on the sample holder.圖中被試驗(yàn)的樣品掛在樣品固定器上。2%) HNO3,相對密度(20176。2%) HNO3, relative density (20176。 在整個(gè)試驗(yàn)過程中，尤其要注意樣品處理時(shí)與地面接觸區(qū)域的警示，避免接觸及劃傷。 這項(xiàng)試驗(yàn)在一個(gè)通風(fēng)櫥中進(jìn)行。硝酸蒸汽測試方法1. TEST METHOD 試驗(yàn)方法The nitric acid used in this test is a strong acid and special caution should be taken. Read Material Safety Data Sheet before starting the test.The test is done in a fume hood. Suitable protective cloths, gloves and eye protection must be used.During the whole test process, particular caution is required for contact areas in sample handling, avoiding any touching/scratching by hands and tools.用在該項(xiàng)試驗(yàn)中的硝酸是一種強(qiáng)酸性,應(yīng)特別警示。試驗(yàn)前閱讀 MSDS。必須穿防護(hù)衣服/手套/ 保護(hù)眼睛器具。 Test Equipment and Chemicals 試驗(yàn)設(shè)備/藥品Below is a list of equipment needed to perform the test: 清單? 2 x vacuum desiccators with ground joint and tap (. Model Novus, Schott NS24/ id. 250 mm)? 2 個(gè)帶磨口連接和活栓的干燥器? Dessiccant, Blue Silica Gel ? 干的/ 藍(lán)硅膠? Sample holder made of inert material (. PTFE / Teflon)? Nitric acid, reagent grade, concentrated (69177。C) to ? 硝酸,試劑等級,濃縮(69177。C) to ? g/cm3. Read Material Safety Data Sheet before starting the test!? 試驗(yàn)前閱讀 MSDS? Density hydrometer (. Widder, scale )? 密度液體比重計(jì)(如,方,刻度 )? Graduated glass (cylinder) 500 ml ? 有
