36、 of the test method,the apparatus shall be recalibrated.7.2.12 Water-retention apparatus and related equipmentshall be checked for conformance to Test Method C 1506 atleast every 212 years.8. Subcontracting8.1 Subcontracting for the performance of part or all of atest method is permitted. When subco

37、ntracting is used thequality of the work provided must be ensured. The require-ments for evaluation differ depending on the permanence of thesubcontracting.8.2 Permanent SubcontractingWhen all or a portion of atest method is subcontracted on a permanent basis then thesubcontracted organization must

38、be subjected to separateevaluation according to this practice for the methods subcon-tracted. The laboratory shall retain a copy of this evaluation forreview by the evaluation authority.8.3 Temporary SubcontractingWhen all or a portion of atest method is subcontracted on a temporary basis then thela

39、boratory shall ensure the quality of the subcontracted work.The level and type of assurance will depend on the extent of thesubcontracting (see Note 3). The laboratory shall retain recordsof this assurance for review by the evaluation authority.NOTE 3Some examples of assurance for different levels o

40、f temporarysubcontracting are: (1) a review of calibrations records when the use of apiece of equipment is subcontracted; and (2) a satisfactory rating on aproficiency sample when a method is subcontracted. Other means ofassurance are test results from a standard reference material or, in the caseof
