Table 1. Calibration and verification of equipment or systems

Equipment /System

Action

Frequency

Microscopes used for measuring

Calibrate stage micrometer

At installation or initial use

pH meters ion selective, and related conductivity equipment

Calibrate against reference buffer E or reference solution at level of use or bracketing range of use

Each day of use

Temperature controlled chambers used for storage (e.g., refrigerators and freezers)

Verify temperature

Frequency is dependent upon mechanism of monitoring F . At installation (or initial use) and after non-routine maintenance G Minimum twice daily on each day of use with at least 4 hours between verifications At installation (or initial use) and after non-routine maintenance G

Uniformity of temperature by mapping the chamber

Temperature controlled chambers used for testing (e.g., ovens, furnaces, incubators, water baths, and autoclaves)

Verify temperature

Uniformity of temperature A by mapping the chamber Calibrate temperature to the appropriate traceable standard

Temperature sensing devices/systems, reference (e.g., thermometers, thermocouples, data loggers, data tracers, thermistors, digital displays, continuous monitors, etc.) Temperature sensing devices/systems, working (e.g., thermometers, thermocouples, data loggers, data tracers, thermistors, digital displays, continuous monitors, etc.)

Every 2 years

Verify temperature against reference device

Annually

Verify working device annually against reference or against NIST time clock I

Timers and Internal Timing Devices H

Time

UV/Vis Spectrophotometer

Verify blank reading

Daily when in use

Verify wavelength

At installation and annually
