Visão geral de conformidade

Esta visão geral está disponível por enquanto apenas em inglês.

Escopo e aplicabilidade

This standard applies to child restraint systems (CRS) designed for installation in power-driven vehicles. It covers various types including integral universal ISOFIX CRS (i-Size), integral specific vehicle ISOFIX CRS, and non-integral booster seats. Manufacturers of any child restraint products intended for the Chinese automotive market must comply with these specifications. It does not apply to non-integral CRS without backrests designed for specific vehicles unless they fall under the defined categories.

Requisitos técnicos

The standard specifies comprehensive general and performance requirements for child restraint systems. It details the structural integrity, material properties, and dimensional constraints for both integral and non-integral systems. Products must meet strict guidelines regarding ISOFIX attachment dimensions and support leg configurations. It also outlines the necessary labeling and instructional documentation to ensure proper usage. Regarding dynamic performance, the standard mandates specific injury criteria limits for crash test dummies during frontal, rear, and side impact collisions. Systems must effectively limit head excursion and chest acceleration to protect child occupants. It also sets requirements for buckle strength, webbing durability, and energy absorption capabilities. Additionally, the standard defines the environmental resistance of components, requiring them to withstand temperature cycling and corrosion without degradation. All materials accessible to children must comply with chemical migration limits referenced in GB 6675.4. Flammability characteristics are also strictly regulated to ensure safety in case of vehicle fire.

Métodos de ensaio

The standard outlines a rigorous suite of testing methods to verify compliance. This includes dynamic sled tests using standard seats and specific crash pulses for frontal, rear, and side impacts. It also mandates rollover tests, corrosion tests, and temperature resistance tests for critical components like buckles and retractors. Furthermore, specific procedures for webbing strength evaluation, microslip tests, and energy absorption tests using a defined headform are detailed.

Perguntas frequentes

What products are regulated under GB 27887-2024?
