9、 on the competence of the personnel performing the procedureand the capability,calibration,and maintenance of the equipment used.Agencies that meet the criteria of Standard Practice D3666 are generallyconsidered capable of competent and objective testing/sampling/inspection/etc.Users of this standar
10、d are cautioned that compliance withD3666 alone does not completely assure reliable results.Reliable resultsdepend on many factors;following the suggestions of D3666 or somesimilar acceptable guideline provides a means of evaluating and control-ling some of those factors.4.Apparatus4.1 One or more a
