Abstract
Overview
EN ISO 8654:2018 (ISO 8654:2018) - "Jewellery - Colours of gold alloys - Definition, range of colours and designation" standardizes how the colour of gold alloys is defined, measured and designated for jewellery and related products. It applies to objects made of, or coated with, gold alloys and provides both quantitative and qualitative methods to determine and communicate colour. This European adoption supersedes EN 28654:1992 and references CIE Publication No. 15 for colourimetry.
