Initial Accreditation Readiness Review for a Calibration Laboratory
TorqueCal is a 12-person calibration laboratory covering torque, pressure and temperature. It intends to apply for initial accreditation in 10 weeks. The management system was documented five months ago. One internal audit has been performed, covering documentation only, and one management review has been held. The proposed scope lists 14 parameters; three of them have no validated procedure, the laboratory saying it follows the manufacturer's manual. Two of the four technicians have no recorded evidence of competence for the newest torque method, which is in the proposed scope. The master torque transducer was calibrated by an accredited laboratory, but the certificate does not state measurement uncertainty for the range actually used. The laboratory plans to put the accreditation symbol on reports from next month. The application form lists both sites of the legal entity, although only one site operates under the management system.
1. Rank the gaps by the risk they pose to a successful initial assessment in 10 weeks. Distinguish what must be closed before the application is submitted from what can be closed before the assessment, and justify.

Must be closed before submission, because the application declares them.
- Scope lines without validated procedures: either validate them or remove them. Declaring a capability that cannot be demonstrated invites a major finding at the first scope item the assessor opens.
- Competence evidence for the two technicians: authorization must exist before the assessment witnesses them work, and the application states they perform the method.
- Two-site listing: either bring both sites fully under the management system, including internal audit and management review, or list only the site that is covered.
- Traceability for the master torque transducer: the calibration chain is the core of a calibration scope.
Can be closed before the assessment. 5. A full internal audit covering all clauses, with vertical traces. 6. A second and properly minuted management review with decisions and owners. 7. Corrective action closure with evidence of effectiveness. 8. Proficiency testing or interlaboratory comparison per parameter where available. 9. Uncertainty budgets covering all 14 parameters.
Justification. An accreditation body assesses against the scope applied for and expects at least one complete cycle of internal audit and management review before the assessment. Ten weeks is realistic for items 5 to 9 if started now; it is not realistic to compensate for undeclared capability gaps on the day. If the readiness review cannot close items 1 to 4, the correct decision is to delay the application, which is cheaper than a failed assessment.
2. For the three unvalidated parameters, the two technicians without competence records and the master torque transducer certificate, state the specific evidence an assessor will expect and the clause basis.

Unvalidated parameters (7.2.1, 7.2.2). The assessor will expect a method description, acceptance criteria and a validation record covering range, accuracy, repeatability and measurement uncertainty, approved by an authorized person. A manufacturer's manual is a method, but using it does not constitute validation unless it is a recognized published method applied without deviation; any deviation needs validation. Expect the assessor to witness the calibration and compare the procedure with the record.
Two technicians without competence records (6.2). The assessor will ask for the defined competence requirements for that method, evidence of training and supervised work, the authorization signed and dated by the responsible person, and evidence of ongoing monitoring of competence. Expect a witnessed calibration and questions to the technician about the procedure and the handling of out-of-tolerance results.
Master torque transducer certificate (6.5.2). The calibration certificate must state metrological traceability and the measurement uncertainty. If it does not, the laboratory must obtain a certificate covering the range used with uncertainty stated, or change provider. The assessor will also ask how the calibration interval was justified and how intermediate checks between calibrations are performed under 6.4.
In each case, the evidence must exist before the assessment. Producing it afterwards in response to a finding converts a manageable gap into a nonconformity.
3. The laboratory plans to put the accreditation symbol on reports from next month and has listed both legal-entity sites in the application. Advise on both points and on how the laboratory should handle a nonconforming calibration discovered during the assessment.

Symbol use. Accreditation is granted only when the accreditation body confirms it, and only for the parameters and ranges listed in the granted scope. Until then, no symbol and no claim of accreditation may appear on any report. Even after the grant, the symbol may not be used for parameters outside the scope or for work performed at an uncovered site. The laboratory should prepare report templates with a controlled accreditation statement that the system switches on only after the grant, and should correct any draft already issued.
Two sites. An assessor will assess what is applied for. If only one site operates under the management system, listing both means the second site will be assessed, or the application will be rejected or reduced. Either extend the management system, internal audit, management review and competence records to the second site before the assessment, or amend the application to one site now. Deciding during the assessment is too late.
A nonconforming calibration found on the day. Handle it openly under 7.10: stop the affected activity, evaluate the significance, determine which certificates may be affected, notify the customers concerned, and initiate correction and corrective action. Do not re-run a calibration to produce a conforming result before reporting it, and do not remove records. Assessors are evaluating whether the system detects and corrects problems; a well-handled nonconformity demonstrates the system works, whereas concealment is treated as a data-integrity failure and can end the assessment.
