In the Netherlands veal carcasses are classified according to colour with the aid of a colour scale. The colour scale, existing of five coloured chips, and the results of its application in the classification system were evaluated both theoretically and practically. The result was that theoretically 75% of the samples were assigned to the same and 25% to a different colour class when assessed by two people. In practice the standardized colour classification of veal in the Netherlands is carried out 45 min post mortem by an independent organization, the 'Centraal Bureau voor Slachtveediensten' (CBS). The correlation coefficient of the results of parallel classifications of 12,659 carcasses between CBS employees and inspectors was 0.88. The CBS employees assigned 80.1% of the carcasses to the same colour class, 10.5% to a colour that was one class lighter and 9.4% to a colour that was one class darker than the inspectors did. It is concluded that high reproducibility and comparability can be achieved uniform implementation of a visual colour classification system.
在荷兰，小牛肉胴体借助色标按颜色进行分类。该色标由五个彩色筹码组成，对其在分类系统中的应用结果从理论和实践两方面进行了评估。结果表明，理论上由两人评估时，75%的样本被归入同一颜色类别，25%被归入不同颜色类别。在实践中，荷兰小牛肉的标准化颜色分类由独立机构“中央屠宰服务局”（CBS）在宰后45分钟进行。CBS员工与检查员对12659具胴体进行平行分类的结果，其相关系数为0.88。CBS员工将80.1%的胴体归入同一颜色类别，10.5%的胴体归入比检查员所归类别浅一级的颜色，9.4%的胴体归入比检查员所归类别深一级的颜色。得出的结论是，通过视觉颜色分类系统的统一实施，可以实现高再现性和可比性。
