Formaldehyde emission test chamber technical requirements of the new standard LY/T1612-2023
1. To meet the standard: LY/T 1612-2023 "formaldehyde emission testing with 1 m3 climatic chamber technical requirements" standard will be formally implemented in 2023 November 1st.
2. The main performance indicators of Formaldehyde emission test chamber in the new standard
2.1 Effective volume: 1.0 ± 0.01 m3.
2.2 Temperature: adjustable range (18~30)℃.
Deviation: ±1℃.
Uniformity: 1.0℃.
Fluctuation degree: ±0.3℃;
2.3 Relative humidity:Adjustment range(40~60)%RH.
Deviation: ±3%RH.
Uniformity: 3%RH.
Fluctuation ±2%RH.
2.4 Flow rate: adjustable range (0.1~0.5)m/s.
2.5 Air replacement rate: Adjustable range (0.2~2.0)h, deviation ±3%.
2.6 Background concentration:Formaldehyde content in the air of the climatic chamber shall not exceed 0.006 mg/ m3 when empty.
2.7 Volume: no sample load when the total volume of the box is about 1 m3, after deducting the heat exchanger, piping, air circulation devices and other auxiliary facilities after the effective material
2.8 Formaldehyde emission test chamber with the inner wall of the climate chamber and its piping and sample racks should not react with formaldehyde, do not adsorb and release formaldehyde, easy to clean inert materials. For example, stainless steel, aluminium plate (sandblasted or polished), glass, et
2.9 Gas tightness: under the over-pressure condition of 1000 Pa, the gas leakage rate is not more than 0.005 m3/min.
