GB/T 18801-2015《空气净化器》国家标准修订若干关键技术研究

Research on several key technologies for revision of GB/T 18801—2015 “Air Cleaner”

近几年,随着我国大气环境中颗粒污染物浓度的持续降低以及新冠疫情的暴发,消费者对居室空气环境质量及空气净化器的使用提出了新的更高要求,GB/T 18801—2015《空气净化器》国家标准亟需在指标的规范性、气态污染物去除评价、病毒去除评价、二次异味评价等方面进行修订。在开展了大量的数据分析和多轮比对试验验证工作的基础上,重点在关联指标建立、气态污染物混合加载试验方法、病毒去除评价及试验方法、模拟二次异味评价及试验方法和动态平衡试验方法等方面开展了深入研究工作,并结合研究结果对GB/T 18801—2015标准进行了补充和完善。修订后的GB/T 18801—2015评价指标更加规范,试验方法的针对性更强,对行业的引领作用更加显著。

In recent years, with the decrease of particle concentration in the China’s atmospheric and the outbreak of COVID-19, consumers have higher requirements for the indoor air quality and the use of air cleaners. Therefore, GB/T 18801—2015 "Air Cleaner" national standard needs to be modified, especially modifications on requirements, gaseous pollutants removal evaluation, virus removal evaluation, and secondary odor evaluation, etc. Based on large amount of data analysis and several round robin tests, research work has been carried out on the establishment of correlation index, mixed loading test method of gaseous pollutants, virus removal evaluation method, simulated secondary odor evaluation and test method of dynamic balance test method. Based on this research results, the standard GB/T 18801—2015 is modified.These modifications makes the evaluation indexes of air cleaners are more standardized and the test methods are more suitable. The revised standard will play a significant leading role in the industry.
