The RAL colour fan decks (RAL Classic and RAL Effect) are not provided with certification but on the inside cover is a hologram which proves that it is a genuine RAL product. These should be used for colour selection and inspiration but are not the official colour standards.
If official standards are required then the registers RAL 840-HR (matte) and RAL 841-GL (glossy) or their individual standard cards should be purchased for RAL Classic standards and the RAL E1 for RAL Effect standards. The Primary standard cards are binding colour standards for colour matching and quality control and include reflectance curves and XYZ values.
