Standard Calibration Procedure

Test Subject: Hole Mike Set

Procedure #: QSCP-105

Revision #: 1.0

Date: 12-11-2012

Approval: James Cagle

1.0Purpose

1.1To establish a standard procedure for calibration of Hole Mike Sets.

2.0Requirements

2.1The calibration laboratory shall be furnished with all items of equipment (including reference materials) required for the correct performance of calibrations and tests. In those cases where the laboratory needs to use equipment outside its permanent control, it shall ensure that the relevant requirements of this section are met.

2.2All measuring and testing equipment having an effect on the accuracy or validity of calibrations or tests shall be calibrated and/or verified before being put into service. The laboratory shall have an established program for the calibration and verification of its measuring and test equipment. The program will ensure the recall or removal from service of any standard or equipment that has exceeded its calibration interval or is otherwise judged to be unreliable.

2.3The laboratory shall use appropriate methods and procedures for all calibrations and tests and related activities within its responsibility (including sampling, handling, transport and storage, preparation of items, estimation of uncertainty of measurement and analysis of calibration and/or test data). They shall be consistent with the accuracy required and with any standard specifications relevant to the calibrations or tests concerned.

2.4The laboratory shall have documented instructions on the use and operation of all relevant equipment, on the handling and preparation of items, and for calibration and/or testing, where the absence of such instructions could jeopardize the calibrations or tests. All instructions, standards, manuals and reference data relevant to the work of the laboratory shall be maintained up-to-date and be readily available to the staff.

3.0Referenced Documents

3.1ISO 17025

3.2NIST Handbook 150

3.3NIST Technical Note 1297

3.4ANSI/NCSL Z540-1

4.0Materials Required

4.1Cleaning solution

4.2Lint free cloth

4.3Cylindrical Ring Gage (Suitable Size)

4.4Certifi Software

5.0Special Precautions

6.0Accuracy / Required Range / Measurement Uncertainties

6.1Accuracy – 0.00025” (as per SPI)

6.2Required range shall be within manufacturer specifications.

6.3If the tolerance is specified by the manufacturer or if customers require tolerances other than specified above, these considerations should govern the acceptability of the test results.

NOTE: Measurement uncertainties are budgeted and calculated using the ISO Guide to the Expression of Uncertainty Management (GUM). Reported uncertainties expressed at approximately the 95% confidence level using a coverage factor of K=2. Unless otherwise stated, a Test Uncertainty Ratio of 4:1 or greater was used. Measurement uncertainty is not taken into account when determining if the instrument under test is within the tolerance limits.

Standards used are traceable to NIST. Calibrationsare in accordance with ISO/IEC 17025, ISO 9000, ANSI/NCSL Z540-1.

.

7.0Procedure

7.1Visually examine the device for any obvious defects that would affect its accuracy or function. Record the “as found” condition of the device onto the Job Log. If discrepancies are noted, discontinue calibration and refer to paragraph 9.1 (Out of Tolerance Conditions).

7.2Verify that identification markings of the gage is distinct and in agreement with the Calibration Work Order.

7.3Determine which size Cylindrical Ring Gage will be suitable to use Hole Mike on.

7.4Select one Certifi Template that represents values within the range of the Hole Mikes.

7.5Clean both the ring gage and hole mike using a cloth and ZEP I.D. Red Cleaner..

7.6Insert the hole mike into the ring gage and open with enough force until ratchet clicks.

7.7Enter findings into Certifi software to produce certificates.

7.8Enter the gage measurements in the measured column and send to table, until all measurements are recorded.

8.0Out of Tolerance Conditions

8.1If any results are found to be significantly out of tolerance during the calibration/verification process, notification shall be made to the customer . If appropriate, state the out of tolerance condition with the associated measurement data so that appropriate action can be taken.

10.0Records

10.1The records for instrument requiring calibration shall include an individual record of calibration. This record shall provide a description or identification of the item, calibration interval, date calibrated, identification of the calibration source, calibration results (data and/or condition status) and calibration action taken (adjusted, repaired, new value assigned, de-rated, etc.).

11.0Calibration Status

11.1Instruments shall be labeled to indicate calibration or verification status. The label shall identify specific date calibrated (date, month, year, Julian date, or equivalent) and the specific calibration due date or usage equivalent. Items not calibrated to their full capability or which have other limitations of use, shall be labeled or otherwise identified as to the limitations. When it is impractical to apply a label directly to an item, the label may be affixed to the instrument container or some other suitable means may be used to reflect calibration status. Tamper resistant seals are affixed to operator accessible controls or adjustments, which if moved will invalidate the calibration. The quality system shall provide instructions for disposition of equipment with broken tamper resistant seals.

12.0Storage and Handling

12.1Instrument shall be handled, stored, and transported in a manner which shall not adversely affect the calibration or condition of the equipment.
