Common use of General test conditions Clause in Contracts

General test conditions. E. 2.1 The general conditions of test are described in IEC 62301 (Household electrical appliances – Measurement of standby power). The main requirements are summarised briefly below. Ambient temperature 23 ± 5 0C Air speed close to the unit ≤ 0.5 m/s Supply voltage 230V ± 1% 50 Hz ± 1% Supply voltage waveform Total harmonic content ≤ 2% Crest factor between 1.34 and 1.49 Power level ≥ 0.5W Power level ≤ 0.5W Power ≤10 W Power 10 ≤ 100 W Uncertainty ≤ 2% at the 95% confidence level Uncertainty ≤ 0.01 W at the 95% confidence level Resolution ≥ 0.01 W Resolution ≥ 0.1 W
