Cleaning procedures shall be consistent with Practice G1. Typically, this may include degreasing with a suitable solvent, followed by vigorous brush scrubbing with pumice powder, followed by water rinse, clean solvent rinse, and air drying. (Warning—Solvent safety and compatibility with the test material should be investigated and safe practices followed). 7.1.2 For the most part, commercially produced stainless alloys and surface ground materials do not require a preexposure pickling treatment. The use of acid cleaning or pretreatments shall be considered only when the crevicecorrosion test is designed to provide guidance for a specific application. |

清潔操作應(yīng)和Practice G1的一致。通常,首先用合適的溶劑去油,然后用刷子完全刷去浮石粉末,后依次用水和溶劑沖洗,最后風(fēng)干。(警告:請(qǐng)先研究清楚所選溶劑的安全性和與所試材料的可相容性,之后進(jìn)行安全操作。) 7.1.2 多數(shù)而言,商業(yè)化生產(chǎn)的不銹合金和表面拋光材料不需要提前進(jìn)行酸浸處理,僅當(dāng)隙間腐蝕試驗(yàn)對(duì)特定用途有指導(dǎo)作用時(shí),才需要考慮酸清潔或預(yù)處理。 |
