verification standards of equivalent requirement(s).
Test Consideration
For optimum performance, all procedures should comply
with the following recommendations.
• Ensure that the ambient temperature is stable and
between 22 °C and 28 °C. The ideal temperature for
performing performance verification should be 25 °C ± 1 °C.
• Make sure that the ambient relative humidity is less than
80%.
• Allow a three- hour warm-up period before performance
verification.
• Keep the test connection cables as short as possible.
