A given respiratory protective device can only be approved when the individual components satisfy the
requirements of the test specification which may be a complete standard or part of a standard, and practical
performance tests have been carried out successfully on complete apparatus where specified in the
appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is
permitted provided the respiratory characteristics and weight distribution are similar to those of the complete
apparatus.
