4、oper application, drying and baking of the specified Teflon. system.體系4.2 Prepare 10% by weight, salt solution by combining 8 tablespoons (106 gr) Table Saltand 4 cups (960 gr) de-ionized water.將 8 湯匙(106 gr)食鹽溶解于 4 杯去離 子水中以得到重量百分比 10%的食鹽溶液。4.3 Prepare a mild dish detergent solution with tap water 用

5、去離子水配備適度濃度 的洗按照產(chǎn)品技術(shù)說明書的程序要求正確準(zhǔn)備測試樣品，干燥并烘烤指定的特富龍涂料滌劑溶液。(5) PROCEDURE 程序(9) Wash the test specimens in dish detergent solutio 用洗滌劑清洗測試樣品。 Rinse incold water.冷水淋洗測試樣品。Dry thoroughly.完全干燥。Visually inspect coating surface for surface defects 肉 眼檢查涂料表面缺陷。 Draw adiagram of the test specimen surface 用 圓規(guī)畫出測

6、試面積表面草圖。 Record allsurface imperfections on the reference diagram.在草圖上標(biāo)出所有 的表面缺陷。Pour the 10% salt solution into the clean test specimen to a level past the midwaypoint of the side wall of the vesse 倒入 10%的食鹽水溶液于測試樣品中， 至少要達 到其內(nèi)壁一半的高度Mark the water level on the side wall of the test specimen 在 測試樣品內(nèi)壁

7、標(biāo)注 水面高度Cover the test specimen with a lid 蓋上蓋子。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 levelwithin 15mm (6.6 inches) at all times 煮沸溶液 24hrs。每隔一定時間(半小時左 右)添加去離子水，以保持水面

8、高度偏差在15mm(6.6 inches 以內(nèi)。The 24 hour period may be continuousor, alternately, may comprise If the 8 hourinterval is used, remove for the heat source safely. 2 小 時可以是連續(xù)，也 可以間斷進行。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 end of each cycle 在 最 后的循環(huán)后傾倒

9、樣品中殘留的鹽水。Wash the test specimenin warm water using the mild dish detergent solution untiladhering 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。Visually examine the test specimensafter each cycle for defects (blisters) notPresent in the initial mapping. Record new defects on the

10、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。Store the test specimens without liquid, dry, overnight.放置無鹽水的樣品，干燥，過夜。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。Visually examine test specimen for defects and record on reference diagram. 用肉眼檢查樣品表面的缺陷并記錄在參考草

11、圖上。(6) EVALUATION 評價Using the supplied Blister Rating Guide, compare the mapping diagram to thefigures for the appropriate rating assessment. Record.使用水泡評級指南來比較草圖上的缺陷，得出合適的評級數(shù)。(7) REPORTING 報告Report the blister rating including 報告水泡級別。bcedf-Numbered_0368c6b7-b104-4c83-9aff-1a631dafddRecord the follo

The test method and the ratingsystem are subjective. Therefore it is rec

13、ommended that for each set of experiments,the reproducibility is measured by including at least one reference (also called“ standard” or control specimen) and data is gathered for each set separately 精 度無法得到，測試方法和評級體系是主觀的。因此，對于每組測試，建議使用參照 品(稱之為標(biāo)準(zhǔn)樣或受控樣品)來衡量測試的重現(xiàn)性，并且分開紀(jì)錄每組測試的數(shù) 據(jù)。e699e7980-Numbered_5ce044e3-c9e5-486f-b540-8293d31562 DOCUMENTS 文檔British Standard BS 7
