T/ZSFX 017-2024 Technical Specifications for the Quality of School Uniforms for Primary and Middle Schools and Kindergartens

Scope

Scope: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage of school uniforms for primary and secondary schools and kindergartens. This document applies to clothing and accessories mass-produced with textile fabrics as the main material, which are worn by students in kindergartens (aged 3 and above), primary schools, junior high schools, and high schools (including technical schools and vocational schools) on a daily basis at school. Other student clothing and accessories provided by schools for activities such as military training and ceremonial occasions may be referenced for implementation. Main technical content: The key terms involved in this standard are the classification of school uniforms, which are mainly divided into three categories: knitted school uniforms, woven school uniforms, and wool-knitted school uniforms. The general requirements of this standard stipulate the fiber content, formaldehyde, pH, odor, decomposable carcinogenic aromatic amine dyes, combustion performance, sharpness of accessories, ropes and belts, residual metal needles, heavy metals, phthalates, and post-washing appearance quality. Separately, it stipulates the washing size change rate, twisting rate after washing, color fastness (water resistance, sweat resistance, dry friction resistance, wet friction resistance, soap washing resistance, light resistance, sweat resistance, splicing cross-dye, and degree of dye transfer from washing solution) of the three types of school uniforms, as well as their performance such as pilling, bursting strength, seam strength, yarn density deviation rate, and square meter dry weight deviation rate.
