Specifications of technical requirements for reflective vests

1. Style requirements

In the style requirements, the requirements for the size, material area and design style of the reflective vest are proposed.

2. Safety requirements

In order to standardize the safety of the use of reflective vests, referring to the requirements of clothing materials and related safety technical standards, the PH value range of reflective vests is proposed, and the requirements of "free formaldehyde content of reflective vests are less than or equal to 75mg/kg".

3. Fluorescent material

The properties of fluorescent materials include: color, color after accelerated sun exposure, wash shrinkage, mechanical properties and color fastness requirements.

4. Retroreflective material

In order to ensure the visibility of the reflective vest, the performance requirements of retroreflective materials are put forward in terms of retroreflection coefficient, sweat resistance, solvent resistance, etc.

5. Garment performance

In order to adapt to the temperature storage environment on the car, the standard puts forward the requirements for the temperature-resistant storage performance of the reflective vest. The test temperature selects the actual high and low temperature storage temperature of the car: low temperature -40 °C and high temperature 70 °C, and the test conditions are alternated in the storage temperature cycle. The fabric of the reflective vest should have no adhesion and no peculiar smell, and the fluorescent material and the retroreflective material should have no color-crossing phenomenon, and the retroreflection coefficient should be greater than or equal to 300cd•lx-1 under the conditions of an irradiation angle of 5° and an observation angle of 12'. • m-2.
