測(cè)試方法：
方法A： 針對(duì)揮發(fā)性化學(xué)試劑。采用預(yù)浸過(guò)化學(xué)試劑的棉球，放置于容積為1盎司的瓶中（10mm x 75mm的試管或類(lèi)似的容器）。 該瓶倒置于所測(cè)試的材料表面持續(xù)24小時(shí)。測(cè)試溫度為：23o +/- 2oC (73o +/- 4oF)。這種方法適用于有機(jī)試劑。
Method A – for volatile chemicals. A cotton ball, saturated with the test chemical, was placed in a one ounce bottle (10mm x 75mm test tube or similar container). The container was inverted on the test material surface for a period of 24 hours. Temperature of test: 23o +/- 2oC (73o +/- 4oF). This method was used for the organic solvents.
方法 B： 針對(duì)不揮發(fā)的化學(xué)試劑。將5滴（1/4cc）化學(xué)試劑置于所測(cè)試材料的表面。然后用25mm的表面皿覆蓋于化學(xué)試劑上持續(xù)24小時(shí)。測(cè)試溫度為：23o +/- 2oC (73o +/- 4oF)。這種方法適用于所列示的除溶劑外的其他試劑。
Method B – for non-volatile chemicals. Five drops (1/4cc) of the test chemical were placed on the test material surface. The chemical was covered with a watch glass (25mm) for a period of 24 hours. Temperature of test: 23o +/- 2oC (73o +/- 4oF). This method was used for all chemicals listed below other than the solvents.
評(píng)估：在持續(xù)放置24小時(shí)后，測(cè)試的區(qū)域先用水清洗，再用清潔劑清洗，然后使用異丙醇清洗。最后用蒸餾水漂洗，用布擦干。
Evaluation – After 24 hour exposure, exposed areas were washed with water , then a detergent solution and finally with isopropyl alcohol, rinsed with distilled water and dried with a cloth.
測(cè)試評(píng)分
1 – 無(wú)影響：在材料表面無(wú)可察覺(jué)的改變。
2 – 優(yōu) 秀： 在顏色與光澤方面有輕微可察覺(jué)的改變，但對(duì)材料表面的功能與壽命無(wú)影響。
3 – 較 好： 顏色與光澤有清晰可辨的改變，但對(duì)材料表面的功能與壽命無(wú)重要影響。
4 – 一 般： 由于變色或腐蝕，外觀有不雅改變。如果延長(zhǎng)測(cè)試時(shí)間，有可能造成功能的損毀。
5 – 失 敗： 表面出現(xiàn)斑痕、坑凹或侵蝕，明顯且重要的材料損毀。
1 – No Effect: No detectable change in the material surface.
2 – Excellent: Slight detectable change in color or gloss but no change in function or life of the surface.
3 – Good: A clearly discernable change in color or gloss but no significant impairment of surface life or function.
4 – Fair: Objectionable change in appearance due to discoloration or etch, possibly resulting in deterioration of function over an extended period of time.
5 – Failure: Pitting, cratering, or erosion of the surface. Obvious and significant deterioration.

抗高溫性能測(cè)試
測(cè)試A：陶瓷坩堝。將置于所測(cè)試材料表面的陶瓷坩堝，加熱至暗紅色然后讓其冷卻，溫度降至室溫。
Test A: porcelain Crucible – A porcelain crucible was heated to a dull red color, placed on the test material, and allowed to cool to ambient temperature.
觀測(cè)結(jié)果：無(wú)起泡，裂縫或任何表面變形。
Observation: No blisters, no cracks nor any surface deformations were observed on the work surface.
測(cè)試B：煤氣噴燈。將一個(gè)3/8〞 的煤氣噴燈調(diào)到穩(wěn)定的火焰使其藍(lán)色錐形內(nèi)焰為1-1/2〞，然后，將煤氣噴燈翻轉(zhuǎn)，是火焰接觸所測(cè)試的材料5分鐘。
Test B: Bunsen Burner A 3/8〞Bunsen burner was adjusted to a quiet flame with a 1-1/2〞inner blue cone and then overturned on the test material, exposing material to the flame for 5 minutes.
觀測(cè)結(jié)果：無(wú)起泡或裂縫。
Observation: No blisters nor cracks were detected on the exposed work surface.
