DIN 45669-2 specifies test methods for evaluating the performance, accuracy, and reliability of vibration measuring instruments used in environmental and occupational monitoring. These tests verify that vibration meters meet metrological requirements and provide consistent, traceable measurements across different operating conditions. The standard covers calibration procedures, frequency response testing, and signal handling verification. Accreditation for this test method ensures that laboratories can validate vibration measurement equipment used in workplace assessments, structural monitoring, and machinery diagnostics. Proper instrument verification is critical for occupational health and safety compliance across industrial sectors.
