• The management must authorize personnel to per to perform specific tasks in the organization.
• The management authorization data for this process should be recorded.

Accommodation and Environmental Conditions

This chapter of ISO/IEC 17025:2005 will define the calibration and test area environment the effects the measurement accuracy.

The key points are as following:

• Environment conditions should not adversely affect the necessary quality of tests.
• The laboratory should thoroughly monitor control and record environmental conditions. For biological sterility, special attention should be paid.
• Laboratory areas with incompatible activities should be separated.
• Authorize personnel should only get access to the test and calibration area.
