适用范围：1.1 This standard specifies test methods for the assessment of the service performance of enamels used for colour coding and colour marking of laboratory glassware. It does not purport to classify enamels by their degree of resistance; it provides standard procedures for determining whether an enamel resists the specified treatment without a change such that the colour can no longer be identified, or might be confused with any other colour used in colour coding.1.1.1 The procedures involve treatment for specified periods with an alkaline detergent solution at 80°C and a dilute acid solution at room temperature.
