3.0 GENERAL REQUIREMENTS3.1 Calibration Laboratory

The vendor employed shall be an approved calibration laboratory listedon the Vendor Approval List, Form WA-5 (Electronic) and shall becapable of meeting all requirements of QP 7.4 (Purchasing Procedures).

3.2 MEASUREMENT STANDARDS AND EQUIPMENT3.2.1 The Light Meter (DSE-100X or equivalent) used as a reference

standard shall be calibrated and traceable to the National Instituteof Standards and Technology (NIST).

3.2.2 The Black Light Source utilized for device calibration shall providea minimum intensity of 2000 w/cm2 of ultraviolet light at the

shortest distance used for calibration.3.2.3 The White Light Source utilized for device calibration shall

provide a minimum intensity of 150 fc of visible light at theshortest distance used for calibration.

3.2.4 The Fixtures(s) used for sensor and/or light mounting shall becapable of providing three (3) fixed distances.

3.3 PROCEDURAL REQUIREMENTSThe calibration laboratory shall have a written procedure ensuringconsistency of the calibration method employed and capable of meetingthe calibration requirements below.

4.0 CALIBRATION REQUIREMENTS4.1 ENVIRONMENTAL CONTROLS

The calibration laboratory environment shall be controlled to the extentnecessary to ensure valid results. Temperature and relative humidityshall be monitored and recorded for future reference.

4.2 MEASUREMENT STANDARD ACCURACYThe reference standard shall demonstrate an accuracy within +/-2% of apreviously established baseline at all recorded ranges. Accuracy shall

be established and recorded prior to calibration of WeatherfordAerospace owned devices.

4.3 BLACK ;LIGHT METER4.3.1 Black Light Meter calibration shall consist of taking three (3)readings to establish linearity of accuracy of the standard reading.

4.3.1.1 Calibrate the black light meter to its range of use:

1000 microwatts w/cm2.

2000 microwatts w/cm2. 3000 microwatts w/cm2.

4.4 WHITE LIGHT METER4.4.1 White Light Meter calibration shall consist of taking three (3)

readings to establish linearity of accuracy of the standardreading.4.4.1.1 Calibrate the white light meter to its range of use:
