GMP Calibration requirements.

All applicable GMP calibration requirements should be encapsulated within a company approved Calibration Management Practices and Procedures manual.  Routine and snap quality audits must be used to confirm past, present and  anticipate future compliance.  The historic records establish with a calibration manager program are essential in facilitating accurate predictive forecasting of any instrument error propagation.

GMP regulated companies often use contract laboratories to satisfy their cGMP calibration reference their measurement and test equipment. If this is the case, FDA views the contract laboratory as an extension of the manufacturer's GMP program or quality system.

Normally FDA does not inspect contract laboratory facilities, but it does expect the manufacturer to audit the contract lab to verify that proper procedures are being used. Generally, the manufacturer of the finished device is responsible for assuring that all GMP calibration requirements are being complied with.  This puts the onus on any auditor to ask about validation and calibration methodologies, techniques and standards used.



Calibration of Sensors

21 CFR Part 820 and 210 mandates that where the accuracy of instruments and or instrument sensors is judged as critical to the final efficacy, quality and or safety of a regulated product or could prove injurious to the integrity of any associated predicated data or data records; the individual instrument must be considered as a, “Critical Instrument”. Critical instruments must be entered into a planned calibration program and subjected to routine calibration against master instruments traceable to national standards, at a periodicity that has a written justification. They must be placarded with a “Calibrated Label”. This SOP lists, details and defines each of the 11 essential elements of cGMP compliant calibration and calibration management. It includes sample document formats, calibration labels layouts and details the importance of the post calibration report. The SOP concludes with a fully detailed; ready to use, Calibration Manager Auditor document. This is your complete calibration SOP to purchase and use.

International Measuring Instruments Calibration.

ISO 9001:2000, requirements must be incorporated into each manufacturer's measuring instruments manager program and form the basis of its quality controlling activities and used to ensure that all calibration delinquencies are removed from existing procedures. A good program can do more than reduce scrap rates. It can reduce expenditures for measurement instruments and related services, add to the confidence and expertise of the company’s staff, and increase the customer's perception of company performance. A good program can protect the company from both routine and more subtle calibration delinquencies and provide records of internationally standardized metrology that would be hard to dispute.


Measuring Instruments Calibration Procedures.

Measurement instruments and tools differ greatly in construction and intent, and the specific activities necessary to calibrate these tools are just as varied. An understanding of the operation of each tool allows problems to be detected, adjustments to be made properly, and condition of tools to be assessed. These technical details are found in all good metrology procedures.

These procedures, to be effective, have to be valid to the tool that will be calibrated. It is very important for a manufacturer to design its metrology procedures around the specific tools and how they will be used to ensure calibration delinquencies do not arise.

There are many sources of historically validated metrology procedures for dimensional metrology tools.

The manufacturers of dimensional metrology tools can also be a great source of valid, proven measuring instruments. Metrology laboratories used for these services may be willing to share their procedures.

Staff experience can also be an excellent source of data on measuring instruments calibration manager procedures.

Traceability


Traceability of a measurement unit is really maintained by a dual chain of metrology that goes back to the international standard. Each comparison is accompanied by an estimation of measurement uncertainty. Measurement uncertainty is calculated through an internationally standardized discipline.

The requirements for measuring instruments calibration manager documented procedures for the control of measurement tools can be found in section 7.6 of ISO 9001:2000. For insight into this section, it is useful to refer to the manufacturing centered 1994 version of ISO 9000. Section 4.11, Control of Inspection, Measuring, and Test Equipment states that measuring equipment is used in a manner that ensures that the measurement uncertainty is known and is consistent with the required measurement capability. The intent of the requirements in both versions is the same. In-house calibrations that are not accompanied by calibration delinquencies have broken the chain of traceability.

Management

An GMP calibration requirements management system strives to attain customer satisfaction through maintaining all sensory systems used in the manufacturing and testing of a regulatory controlled product operating within their design specification.

The management of GMP calibration requirements management system is accomplished in the same way as management of the other processes identified in the manufacturer’s management system.  This manager program must also log calibration delinquencies that arise to allow predictive analysis of any instrumentation errors.

Some manufacturers may choose to develop a system manual which contains the process description, planned quality objectives, key indicators of process performance and references to the standards and procedures in use. This can become a very valuable document that serves as the road-map to a dynamic and  effective, GMP calibration requirements solution.

Validation Risk Assessment (Issue11.) -- $125.00

The Risk and Part 11 Validation Risk Assessment (VRA) protocol is becoming the most important document in the validation train. The VRA reassures the regulators that you have looked at specific equipment functionality and considered the appropriate level of validation that is required. You have also considered various aspects of its use and the implications of any malfunctions. From the results of this exercise the scope of all validation activity can and must be justified. This is a robust and simple to execute document, one that will lead you through the process and deliver a result that can be used as the foundation for your validation activities.
This VRA now includes the assessment table for categorizing and documenting the new 21 CFR Part 11 guidance ruling on what predicate data must be stored in a Part compliant system, along with the new broadsheet to establish your new database of part 11 records. (now mandatory).

Equipment combined IQ/OQ/PQ Protocol.

This combination protocol has been produced in response to several hundred reader suggestions we received in our ‘Suggestions Section’. It has been carefully designed to make it the preferred choice for Process and Laboratory stand alone equipment. It is interactive, easy to use and suitable for all mixes of equipment with and without software.
The IQ section establishes documented verification that key aspects of the equipment adhere to approved design intentions and that the recommendations of the manufacturer have been suitably considered. The OQ section establishes that there is documented verification that the installed system functions as specified and that there is sufficient documentary evidence to demonstrate this. The PQ section gives documented verification that the equipment performance in its normal operating environment is consistently exactly as specified in the URS.
