21、ity systemand its implementation. The quality manager ensures thatactivities are being conducted by agency staff in the mannerspecified in the agencys quality system manual and hasresponsibility for maintaining and revising it. This individu-al(s) shall have direct access to top management (see Note

22、 2).NOTE 2This individual(s) may have other responsibilities (for ex-ample, laboratory manager).7.1.3 Laboratory Procedure ManualA written laboratoryprocedure manual outlining the method or inspection proce-dure for each test or service performed by the laboratory.NOTE 3Inspection and testing proced

23、ures may reference publishedstandards.7.1.4 Equipment Calibration and VerificationThe agencyshall calibrate or verify all significant testing equipmentassociated with tests covered by the scope of this standardwhich the agency performs. As a minimum, the equipmentlisted in Table 1 shall be included

24、if it is associated with testsperformed by the agency. Applicable equipment shall becalibrated or verified at the intervals specified in the agencysQSM. The intervals specified in the QSM shall be no greaterthan those indicated in Table 1 (see Note 4). Newly acquiredequipment without manufacturers c

25、ertification and equipmentthat has not been calibrated or verified because it has beenremoved from service shall be calibrated or verified beforebeing placed in service. The agency shall have detailed writtenprocedures for all in-house calibration and verification activi-ties not addressed in standa

26、rds. These procedures shall indicatethe equipment required to perform the calibration or verifica-tion.NOTE 4When a maximum calibration or verification interval for aspecific piece of test equipment is specified in a standard, the maximuminterval specified by this practice is intended to be the same

27、 as themaximum interval specified by the standard.7.1.5 Inspection of FacilitiesThe agency shall have itslaboratory procedures and equipment evaluated at intervals ofapproximately two years by an evaluation authority (see Note5) as evidence of its competence to perform the required test.Within 30 da

28、ys of the receipt of the evaluation authorityswritten report, the agency shall address or correct any deficien-cies cited in the report.
