ZB 57001-1986 "General Technical Conditions for Painting Toy Metal Surfaces" is a toy industry standard that specifies the technical requirements for painting toy metal surfaces. The content covers film performance indicators (adhesion, hardness, impact resistance, etc.), limits of harmful substances (such as heavy metals content), Appearance mass (color uniformity, sag, particles, etc.), test methods (such as cross-cut adhesion, chemical analysis of heavy metals) and inspection rules. The standard is applicable to the painting process of all kinds of toy metal parts, which aims to ensure the safety and durability of coatings, prevent children from contact with harmful substances, and ensure that the paint surface is anti-abrasion and anti-corrosion, providing technical basis for the production and inspection of toy metal paint, helping to standardize the industry and protect the safety of children.
