Color measurement of high-visibility clothing according to DIN EN ISO 20471

Reflective high-visibility clothing must meet certain criteria in terms of color and luminosity in order to be certified in accordance with DIN EN ISO 20471. In particular, the properties of the material must withstand certain stress tests during production. But it must also be checked during use, after each cleaning, whether the color and luminous qualities of the clothing comply with DIN EN ISO 20471.

HunterLab’s MiniScan EZ and ColorFlex EZ devices provide straightforward yet highly accurate measurements to ensure that the color quality of high visibility garments meets the standard before they leave the factory or dry cleaners, providing the wearer with adequate protection in hazardous areas.

Application example:

Color measurement of high-visibility clothing according to DIN EN ISO 20471

The DIN EN ISO 20471 standard for high-visibility clothing specifies not only the size and shape of the clothing and the position of the retroreflective stripes, but also the requirements for the color and luminosity of the material. These must be fulfilled in particular after various test procedures with regard to stress and ageing, as well as in use after each cleaning, before delivery. Both the portable MiniScan EZ (4500L) handheld device and the ColorFlex EZ laboratory device from HunterLab are ideal for measuring the color of high-visibility clothing. These double-beam spectrophotometers have a 45°/0° measuring geometry in accordance with the standard and can output the measured...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
