Noise test method for household and similar electrical appliances Special requirements for fan heaters1 Scope and measurement volumeThis chapter of GB/T 4214.1-2017 is applicable except for the following contents. 1.1 Scope 1.1.1 Overview replace. This document is applicable to fan heaters installed on the floor, countertop, cabinet or wall. This document does not apply to. ---Heat storage indoor heater; ---Room humidifier; ---Room dehumidifier; ---air purifier; ---Industrial dedicated heater. 1.1.2 Types of noise replace. The methods in GB/T 6881.2, GB/T 6881.3-2002 and GB/T 3767 are suitable for measuring the emission of fan heaters noise. 1.1.3 The size of the sound source replace. The method specified in GB/T 3767 is applicable to sound sources of any size. When adopting GB/T 6881.2 and GB/T 6881.3-2002 At this time, it should be noted that the maximum size of the device under test should meet the requirements specified in GB/T 6881.2 and GB/T 6881.3-2002 in 1.3. 1.2 Measured amount Increase. The measurement frequency range of the sound power of the fan heater includes at least the octave band of the center frequency of 63 Hz to 8000 Hz. Note 1.In many cases, the 63Hz octave band contributes little to the A-weighted sound pressure level. Note 2.When measuring the 63Hz octave band, special attention should be paid to the influence of the test room. The explicit requirements for noise emission values are outside the scope of this document. Note 3.For the measurement and verification of the noise emission value indicated in the product specification, see IEC 60704-3. 1.3 Measurement uncertainty replace. According to the estimated standard deviation of the sound power level determined in this document, see Table 101. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4214.12-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 4214.12-2021_English as soon as possible, and keep you informed of the progress.
