19、corrosion test specimens WARNING Safety rules for personnel: handling of the solutions used for removal of corrosionproducts must be left to skilled personnel or conducted under their control. The equipment mustbeused and maintained by skilled personnel, not only so that the procedures can be perfor
20、med correctly, but also because of the hazards to health and safety that are involved. 1 Scope This International Standard specifies procedures for the removal of corrosion products formed on metal andalloy corrosion test speci mens during their exposure in corros ive environments. For the purpos e
21、of thisInternational Standard, the term “metals” refers to pure metals and alloys. The specified proceduresare designed to remove all corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal, which occurred during exposure toth
22、e corrosive environment.These procedures may, in some cases, also be applied to metal coatings. However, possible effectsfrom the substrate must be considered. 2 Procedures2.1 General 2.1.1 A light mechanical cleaning treatment by brushingwith a soft bristle brush under running water should first be
23、 applied to remove lightlyadherent or bulky corrosion products. 2.1.2 If the treatment described in 2.1.1 does not remove all corrosion products, it willbe necessary to use other procedures. These are of three types:a) chemical; b) electrolytic; c) more vigorous mechanical treatments.NOTE These trea
24、tments will also remove some base metal. Whichever method is used, it might be necessary to repeat the cleaning treatment to ensure completeremoval of the corrosion products. Removal shall be confirmed by visual examination. The use of a low-powermicroscope (i.e. 7 to 30) is particularly helpful wit
