At present, there are many indoor environment detection institutions in the society, and the indoor environment detection is highly professional, which often makes consumers dazzle when choosing. Then how to select a regular indoor environment detection organization? Ordinary detection users must pay attention to the following points: "CMA authoritative test report sample", please visit: http://www.in-air.com/CMA_Demo.htm Hyperlink! Google and Baidu can search the CMA certificate number of the testing agency to identify the authenticity of the testing agency! 1: Is the selected testing organization qualified for CMA testing? CMA is the abbreviation of "China Metrology Accreditation", which means "China Metrology Accreditation" in Chinese. CMA testing institutions must have the following qualifications: according to the regulations on metrological accreditation management, the data issued by testing institutions that have passed the metrological accreditation can be used for trade certification, product quality evaluation, and achievement signing as notarized data, which has legal effect* It is illegal for technical institutions without CMA measurement certification to provide notarized data for the society! Violation of laws must be prosecuted Therefore, under the pretext that it is unnecessary to issue CMA test reports without litigation, the institutions that do not issue CMA test reports ask consumers to consider. 2: Does the selected testing agency read the testing data on site? At present, in addition to allowing radon and formaldehyde to be detected by on-site portable instruments, the national standard allows that benzene, toluene, xylene, TVOC and other indicators to be sampled on site and returned to the laboratory for precise measurement, parameter analysis, report writing, quality audit and other procedures. Generally, it takes more than 3 working days to get the test results, which is impossible to get the results on site. Therefore, the testing agency that claims to be able to produce the test results on site immediately asks consumers to consider. 3: Does the selected testing organization provide governance products? The truly authoritative CMA detection agency will not sell any pollution control products and provide pollution control services to users. It can tell you what methods can be used to avoid indoor air pollution at most. Otherwise, when it is both a referee and an athlete, the authenticity and authority of the detection data will be greatly reduced. Therefore, the testing institutions responsible for both testing and governance invite consumers to consider. 4: Does the selected testing agency charge fees strictly according to international testing projects? The Indoor Air Quality Standard (GB/T 18883-2002) stipulates that there are 19 international testing items, and the Indoor Air Quality Standard stipulates that in South China, there are 6 mandatory testing items related to "indoor decoration and furniture": formaldehyde, benzene, toluene, xylene, radioactive radon, TVOC. The testing instruments and methods for each pollutant have different requirements! Therefore, the inspection institution that claims that one instrument can measure one household and multiple items asks consumers to consider.
