DIN EN ISO 10650:2017-05

This amendment adds an upper limit to the radiant exitance (irradiance) for the 385-515 nm wavelength region, radiant exposure (dose), a measurement for LED lamps with emission in the 385-400nm range and an alternative test method (Method B) to measure the radiant exitance (irradiance) of powered polymerization activators. There is a risk of tissue damage caused by heat development during photo-polymerization. There is also a risk of inadequate polymerization of resin-based materials when irradiated by very high irradiance and very short irradiation time such as 1 s. The amendment therefore incorporate limits on radiant exitance (irradiance) and radiant exposure (dose).
