It is true that you can’t make you can deliver 100% qualified products to customers even you have the best technology, best production equipment and best process control. A serial of testing machines and testing methods are critical to support you to find, analyze and solve the problems. The laboratory capability sometimes represents a company’s attitude and capability for quality control and new technology development.
WeeTect has two world class laboratories in China. Both of them align with CE certificate laboratory. One of the laboratories is located in our Foshan factory which focuses on eye and face protection. This laboratory aligns with ECE324/22.05. The testing equipment list as following: Anti-fog Testing; Hardness Testing; Spectral Transmittance Testing; Scattering Testing; Refractive Power Test; Impact Resistance; Abrasion Testing; UV Aging; etc.
Another laboratory is located in our Wuxi factory which focuses on Auto Darkening Welding Helmet. This laboratory aligns with CE EN379/ ANSI Z87.1/ CSA Z94.3. The testing equipment list as following: ADF Measurement Device for Shade; Cary 4000 Spectrophotometer; Measurement Device for Homogeneity and Angle Dependence; Measurement Device for Switching Time; On-line Automatic Testing Device; Measurement Device for Light Scattered; etc.
Check Testing Details Below
Refractive Power Testing
Refractive power testing is an optical clarity test with spherical and astigmatic reflective powers to check the diopter of the visors which complaint with ECE324.
Impact Resistance Testing
Impact resistance testing measures the visor which cover the lower part the face and intended to protect the chin of the user against impacts which complaint with ECE324.
UV Aging Testing
UV aging testing measures the longevity of our polycarbonate visors when expose to ultraviolet, extreme temperature and moisture which is an additional test beyond ECE324 by our company.
Hardness testing measures the hardness of our polycarbonate visors inside and outside to make sure the helmet visors will not easy to be scratched which complaint with ECE324.
Abrasion testing measures the light diffusion rate before and after abrasion to secure our helmet visors abrasion resistant coatings are good enough whilse complaint with ECE324.
Anti-fog testing also names mist-retardant testing to check if the square of the specular transmittance has not fallen below 80 per cent of the initial value without misting within 20 sec. Our testing result is 24 sec complaint with ECE324 testing method.
Viscosity testing measures our helmet visors graffiti resistant rate when they are splashed by liquid which is critical to secure the riders on emergency.
Spectral transmittance measures the value between 380nm and 780nm of our helmet visors to make sure they fit with the spectral visibility function of the average human eyes for daylight vision.
The requirements on scattered light shall be measured and assessed over an area 5 mm in diameter which includes the presumed error.
