This International Standard specifies a method of measuring the total reflectivity of flat surfaces of anodized aluminium using a photoelectric reflectometer.
The .Tiethod is applicable to achromatic (non-coloured) surfaces of any texture or lightness. It is regarded as an approxi-mate method and is most suitable for production control purposes. For more accurate measurement, reference should be made to ISO 6719, Anodizing of aluminium and its alloys — Measurement and calculation of reflectance charactenstics using integrating sphere instruments
