Amendment A11:2021 to EN 60825-1 was published and offered to the European Commission to be listed as harmonized standard under the Low Voltage Directive. This is a “Europe” only
amendment, i.e. there is no equivalent amendment at the IEC level. With the exception of the wavelength range between 1250 nm and 1400 nm, the requirements of A11 will affect only a
relatively small number of products.
Dr. Karl Schulmeister was project leader for A11 and has written a White Paper discussing the content of A11, which is available for free download.
