ISO 4630:2015 specifies a method for estimating the colour of optically clear, yellow/brownish coloured liquid products by means of the Gardner colour scale using colour-measuring instruments. The method uses the Gardner colour scale described in Annex A. It is applicable to drying oils, varnishes and solutions of fatty acids, polymerized fatty acids, resins, tall oil, tall oil fatty acids, rosin and related products. The results might be invalid if other products are tested. The method described provides a more precise way of measuring Gardner colour than a visual sample comparison using human eyes. It is applicable to products having colours from Gardner 1 to Gardner 18. The Gardner scale is not applicable to products with colours darker than 18. For products with colours lighter than Gardner 1 the method specified in ISO 6271 applies.
Abstract
Overview
EN ISO 4630:2015 - Clear liquids: Estimation of colour by the Gardner colour scale (ISO 4630:2015) defines an instrumental method to estimate the colour of optically clear, yellow/brownish liquids using the Gardner colour scale. Issued by CEN/ISO, this consolidated third edition replaces earlier visual-comparison procedures and standardizes a spectrophotometric approach for more precise, reproducible colour measurement of products such as drying oils, varnishes, resins, tall oil and rosin solutions.
Key Topics
- Scope: Applicable to optically clear, yellow/brown liquids with colours from Gardner 1 to Gardner 18. Not suitable for darker (>18) or extremely light (
