Floor products repeatedly exposed to quality problems

At present, with the repeated exposure of flooring products to quality problems, some consumers are also worried about the quality of flooring products, especially the issue of floor formaldehyde emission, so many homes will be invited to the relevant testing department for indoor air after renovation. Quality testing, but there are numerous checkpoints on the air detection.

Numerous certification bodies in the certification process

Faced with the choice of “rich and diverse” testing organizations, who should be believed by professionals who are not professionals? In this regard, indoor environment management expert Qu Lingbo suggested that consumers pay attention to two things. First, it is not uncommon to see whether the relevant agencies are the authoritative inspection agencies authorised by the state. Of course, non-authority inspection units with the word "authority" are not uncommon, and the state's licenses are indispensable, and often such certificates have deadlines. Expired is inevitably invalid.

Secondly, as a comprehensive certification and evaluation of the testing agency's testing capability and reliability by the measurement administrative department, the CMA qualification certification (by the provincial administrative authorities of the people's government above the provincial level for their capacity for measurement verification and testing and reliability Appraisal pass is the most important and trustworthy testing organization. Its report should have the CMA certification mark.

In addition, Qu Lingbo said that too cheap testing costs and relatively high detection costs will certainly reflect the difference in the test results, but this does not mean that there is no basis for the testing agencies are all over the sky are trustworthy. If you want to not be deceived, consumers are indispensable for learning related knowledge and processes.

Detection method is ambiguous

After understanding the different quotations from the three agencies, a big question mark arises. How will each of them explain the difference in price several times? Calling the China Indoor Climate Testing Center, the most expensive of the three organizations, once again asked the reason for the phone, the other party explained: “Now there are some testing organizations that charge relatively cheaply, but from what I understand, it may be that different detection methods are used. We are atmospheric samples that meet national standards. Some of them use direct-reading instruments (portable testing instruments, which can directly read formaldehyde content data in the field), and the data obtained will be rough, and we will be very precise. With this cost, the price may be higher."

However, the same problem was found in the lower-priced XX authoritative indoor environmental monitoring center: "The detection unit of the national prefix, the service targets are all major projects, not for the average consumer, and the charging standards are According to the engineering fees, when asked about the detection method, the other party sums up the sentence in a sentence: “It is a test method that conforms to the standard.” “Is it a direct-reading instrument or an atmospheric sampling experiment?” Still said, "This is the standard sampling method."

The Beijing Institute of Product Quality Supervision and Inspection, which has its price in the middle, gave another argument. “We don’t know what the reason for the relatively high price of the test is that it is too expensive and unnecessary. This industry is chaotic and many organizations are detecting fees. Low, but they are likely to give a relatively high data on the test results, and then asked to help you do the indoor air environment governance, this treatment, the charges will go up.Frankly, they are doing a kind of bundled sales. ”
