Note: The presence of equipment alone does not indicate a satisfactory situation. Assessors must evaluate the equipment design, calibration,
uncertainty and documentation to ensure compliance with the directions of the standard. The requirements of ISO/IEC 17025 regarding validation are
applicable, as the tests of this standard are not standardised tests.
