GB/T 34626.1-2017 in English

This document specifies the methods for cleaning and preparing metal surfaces, particularly those of steel and its alloys, prior to the application of metallic and other inorganic coatings. It covers various cleaning processes, including mechanical, chemical, and electrochemical methods, as well as the preparation of surfaces to ensure proper adhesion of coatings. The scope includes the evaluation of surface cleanliness and the determination of surface condition after preparation. The document provides guidelines for selecting appropriate cleaning and preparation techniques based on the type of coating to be applied and the specific requirements of the application. It also outlines procedures for testing and inspecting cleaned and prepared surfaces to verify compliance with specified standards. This part of the standard is applicable to a wide range of industries where surface preparation is a critical step in the coating process.
