Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing

Targets #

Testing Targets 2019
Non-pharmaceutical consumer goods (trade descriptions) within reporting time averaging 35 working days (%) 92 98 97 92

For targets where reporting time is mentioned, different samples require different analytical procedures, hence different reporting time. The quoted number of working days required represents an average of reporting time for the different types of samples and test requests within the category, while the target (in percentage) is the total compliance rate of the concerned samples and test requests within a particular category against their respective targets.
