Escopo e aplicabilidade

This standard applies to children umbrellas designed for use by children aged 3 years and above. It covers specific safety technical requirements for both manual and automatic opening umbrellas where the length from the umbrella cap to the bead tail is 50cm or less. Manufacturers must ensure compliance if their products target the Chinese children's market. It does not apply to standard adult umbrellas.

Requisitos técnicos

The standard specifies strict safety requirements for use, ensuring that accessible parts do not have sharp edges or exposed wire ends. It mandates that no pinch points are generated during normal operation. Additionally, automatic umbrellas must have a specific button force range, and the umbrella must withstand 400 consecutive open and close cycles without parts falling off. Physical dimension and structural integrity requirements are defined for critical components such as the umbrella cap, bead tail, and handle. These components must feature spherical or rounded shapes to prevent injury, with specific minimum diameter and height limits. The standard also sets fastness requirements for component connections, including the joint between the shaft and handle, to withstand designated pulling forces. To protect children's health, the standard enforces harmful substance limits. This includes restricting the migration of soluble elements like lead, cadmium, and mercury in the handle, as well as limiting formaldehyde and decomposable harmful aromatic amine dyes in the umbrella canopy, referencing GB 6675-2003 and GB/T 2912.1. Furthermore, the standard outlines requirements for impact strength and the pull force resistance of strap buckles and decorations. If decorations detach after a pull test, specific warning labels must be provided.

Métodos de ensaio

The testing methods involve visual and tactile inspections to identify sharp edges and pinch points. Dimensional measurements are conducted using vernier calipers for the umbrella cap, bead tail, and handle. Mechanical tests include pull tests for component fastness and strap buckles, a drop test for impact strength, and endurance testing through 400 open/close cycles. Chemical analyses are performed to test for harmful substances according to GB 6675-2003, GB/T 2912.1, and GB/T 17592.
