3.0 SAFETY PRECAUTIONS 安全防范

This procedure may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.0 CONDITIONING 条件

The test surface shall be a panel or part as specified in the applicable Material Standard and aged for 72 hours prior to testing.

测试的表面应该是在适用材料标准中指定的测试板或零件并且在进行实验前老化72小时。

5.0 SAMPLING 取样

Refer to the applicable material. 参考适用材料

6.0 PROCEDURE*** 步骤

After testing the material with any of the following methods, the paint film shall exhibit no detrimental effects such as appreciable softening, swelling, loss of adhesion.

在用下面方法对材料进行测试后，漆膜不应该出现有害的外观如可察觉的软化，膨胀黏附性丢失。Method A - Hot Immersion Test方法一 -热浸渍测试

A. Immerse the painted test panel so that 75% of the panel is submerged in the test fluid. Test should be run at 180 degrees F (82 degrees C).在样板上刻划， 75% 的部份浸入测试液体中。测试应该在 180 度 F(82 度 C) 被进行。

B. This should be done in a sealed container if the test fluid is highly volatile. CAUTION: Do not heat flammable materials with an open flame.如果测试液体高度挥发性，这应该在一个密封的容器中被做。小心: 不要用开着的火焰加热易燃的材料。

C. Length of submersion time is as specified in the applicable Material Standard. If no immersion

time is specified, use 2 hours.淹没时间的长度按标准的要求。如果浸渍时间没有指定,使用 2 小时。

D. Inspect panels after 4 hours of recovery.样板恢复后4 小时进行检查。

Method B - Spot Test

方法B - 点滴实验

A. Prepare 3 pair of scribed panels labeled 5, 18, and 24 hours. Each scribe consists of a one inch X through all coatings and into the substrate of the sample.

准备3对用划线器划过的测试板标记5，18和24小时。每个划线由一个一英寸X穿过所有的涂层并且进入样本的底材。

B. Apply the test fluid by drop to the center of each X until a spot diameter of one inch is reached without run-off.

在每个X的中心滴入实验液体直到液滴的直径达到一英寸并且无流失现象。

C. Immediately, after the appropriate time interval (5, 18, and 24 hours), wipe off any remaining fluid and inspect panels.

在适当的时间间隔（5，18和24小时）后，立刻擦去留存的任何液体并观察测试板。

D. Rewipe any residue from the panel, with a dry or wet cloth, prior to storage.

在进行储藏前用一块干燥或湿布再次擦拭实验板的残留物。

Method C - Dip Test

This method should be used only with volatile liquids. For water test only - use water at 100 degrees C (212 F).

A. Scribe the center of a painted panel. The scribe consists of a one inch X through all coatings, into substrate.

B. Immerse the test panel so that 75% of the panel is submerged in the test fluid for 15 seconds.

C. Remove and allow to dry for 2 minutes.

D. Repeat the dip cycle 10 times.

E. Inspect the test samples after 30 minute recovery time.

Method D - Suntan Lotion Test

方法D - 太阳油测试

Three samples should be run per condition.

事先预备三个样本

A. Place a crock cloth on the painted panel.

在喷图板上放一块脱色布

B. Place one drop (0.07 to 0.13 g) of Suntan Lotion (Coppertone Waterbabies 30 SPF) on the crock cloth.

在脱色布上滴一滴（0.07至0.13克）的太阳油（Coppertone牌水宝宝30SPF）

C. Cover the drop and crock cloth with an aluminum panel.
