5、detergent solution with tap water. 用去離子水配備適度濃度的 洗滌劑溶液。(5) PROCEDURE 程序5.1. Wash the test specimens in dish detergent solution用. 洗滌劑清洗測試樣品。Rinse in cold water. 冷水淋洗測試樣品。Dry thoroughly. 完全干燥。Visually inspect coating surface for surface defects用. 肉眼檢查涂料表面缺陷。 Draw a diagram of the test specimen surface.

6、用 圓規(guī)畫出測試面積表面草圖。 Record all surface imperfections on the reference diagram. 在草圖上標(biāo)出所有的表 面缺陷。5.2 Pour the 10% salt solution into the clean test specimen to a level past the midway point of the side wall of the vessel. 倒入 10%的食鹽水溶液于測試樣品中， 至少要達(dá)到 其內(nèi)壁一半的高度Mark the water level on the side wall of the test s

7、pecimen. 在測試樣品內(nèi)壁標(biāo)注水 面高度Cover the test specimen with a lid. 蓋上蓋子。5.3. Place the test specimen on the heat source. Boil the solution for 24 hours.將 測試樣 品放在熱源上，加熱溶液 24hrs。Boil the solution for 24 hours. Add de-ionized water to maintain the water level within 15mm (6.6 inches) at all times.煮沸溶液 24hrs。每隔

8、一定時間(半小時左右) 添加去離子水，以保持水面高度偏差在 15mm(6.6 inches)以內(nèi)。The 24 hour period may be continuous or, alternately, may comprise If the 8 hour interval is used, remove for the heat source safely. 2小4 時可以是連續(xù)， 也可以間斷 進(jìn)行。比如可以選用 8 小時一個循環(huán)，總共三個循環(huán)。煮完后安全地從熱源上 移開樣品。Pour the remaining liquid from the test specimen at the e

9、nd of each cycle.在 最后的 循環(huán)后傾倒樣品中殘留的鹽水。5.4 Wash the test specimen in warm water using the mild dish detergent solution until adhering salt deposits are completely removed.使用溫和的洗滌劑在溫水中清洗樣品，直至殘留的鹽分完全洗掉。5.5 Visually examine the test specimens after each cycle for defects (blisters) not Present in the ini

10、tial mapping. Record new defects on the reference diagram. 每一循環(huán)結(jié)束后用肉眼檢查樣品表面新的缺陷(水泡) ，并在參考草圖上標(biāo)注。5.6 Store the test specimens without liquid, dry, overnight. 放置無鹽水的樣品，干燥，過夜。5.7 Repeat the process until a complete 24 hours is completed. 重復(fù)程序，直到完成 24hrs 的測試時間。5.8 Visually examine test specimen for defec

11、ts and record on reference diagram. 用肉眼檢查樣品表面的缺陷并記錄在參考草圖上。(6) EVALUATION 評價6.1.
