JB/T 15431-2026Earth-moving machinery - Remanufacture of components - General technical requirements of post treatment for thermal spraying coating (English PDF)

JB/T 15431-2026 is the English-translated version of 土方机械零部件再制造热喷涂涂层后处理通用技术要求.

JB/T 15431-2026 gives the general technical requirements for the post treatment of thermal spraying coatings applied when components of earth-moving machinery are remanufactured. Remanufacturing restores worn parts, and thermal spraying is one way of rebuilding their surfaces. The standard concerns the treatment carried out on the coating after spraying. It is a basic standard.

Remanufacturers of earth-moving machinery parts, machine makers, coating service companies, test laboratories and buyers of remanufactured components use it. It is a voluntary industry standard, shown by the /T in its code. The Ministry of Industry and Information Technology issued it on 28 April 2026, and it takes effect on 2 November 2026. It is a new standard.
