31、 given in Table 5. In order to be able to achieve compliance with the maximum error limits specified in Table 5, a VMF of a given class can have its maximum error at reference temperature constrained to a value lower than the maximum allowed by the accuracy class as specified in Table 4. If this is

32、the case, the supplier shall declare this lower maximum error limit at reference temperature and give evidence to demonstrate this lower limit will ensure the maximum limits given in Table 5 are not exceeded.
