Hainan Qionghai newly renovated office wants to be a in addition to formaldehyde. How to find a professional in addition to formaldehyde institution? Give some advice with experience. Thank you!

It is suggested that you can arrange professional CMA formaldehyde detection before or after formaldehyde treatment, so that the CMA detection data obtained is fair and objective.

It is recommended to find a professional CMA company to test and test the data fairly and authoritatively. It is best not to find a testing company without CMA qualification for testing. Such test data is uncontrollable and can be adjusted artificially.

According to the number of points you test, the price is different depending on the test items; Routine detection items include: formaldehyde, benzene, toluene, xylene, TVOC, ammonia, radon, etc. , you can choose according to your own situation.

Let me give you an overview of the test.

It is suggested to adopt GB/T 18883-2002 indoor air quality standard for home testing or strict requirements (close doors and windows 12 hours in advance).

Focus 1. Formaldehyde testing should be carried out by institutions with CMA qualifications that only test and do not manage. CMA test report can be used as a formal occasion and legal reference fairly and objectively. The fairness and objectivity of unqualified test are questionable, and the report has no effect.

Second, focus on the detection of formaldehyde. Never look for a company for testing and treatment. Because China's laws prohibit the same company from testing and governance. For details, please refer to 4. 1.5 of the National Criteria for Accreditation of Laboratory Qualification: the laboratory and its personnel may have an interest in the testing and/or calibration activities and the data and results issued by it.

Focus 3. The common pollutants in newly renovated places are: formaldehyde, benzene, toluene, xylene, TVOC, ammonia, radon and so on. It is suggested that more substances can be detected.

Focus 4. The setting of detection points generally takes an independent space as a point. If it's a family, such as two rooms and one living room, it's generally recommended to get three points in two rooms and one living room. The suggestion that the kitchen toilet won't stay in it for a long time is unexpected. If it is a large space, according to the standard, set a detection point of 30-50 square meters. Of course, time detection can be planned according to the customer's budget and demand.

Choose to identify whether CMA formaldehyde testing company is formal, mainly pay attention to the following points:

1. Is the qualification complete?

Check whether the company has a business license and CMA qualification certificate, the registered address of the business license and CMA qualification certificate, and the address of the testing laboratory is in the same place. (It is suggested that you can make a field trip if you have the conditions. )

2. Is it a local CMA testing organization?

It is recommended that customers who do CMA testing directly look for local formaldehyde testing institutions. If it is a foreign testing organization, especially ordinary family customers, testing companies in other provinces are prone to many problems in the testing process (for example, formaldehyde needs to be sampled and analyzed within 24 hours, which is generally impossible in other provinces), and loopholes are prone to occur. If it is used in formal occasions, it will be questioned that the report is invalid.
