Radiation protective clothing market rebound fabric shielding effectiveness using national standards

As a pregnant mom standard radiation protection clothing sales recently warmed up. Previously, the radiation protection service market that was once caused by misinformation entered the repair period. For the public concerned about the radiation protection service, the reporter visited the relevant industry associations and testing organizations.

Radiation Protection Industry Association: Radiation shielding fabrics use national standards for shielding effectiveness

Regarding the national standards for radiation protection suits that are the most concerned for pregnant mothers, Huang Jianhua, member of the National Electromagnetic Shielding Materials Standardization Technical Committee and spokesman of the Shanghai Anti-electromagnetic Radiation Association, said: Although there are no national standards for radiation protection suits, radiation protection fabrics are available. According to national standards, the shielding effectiveness of fabrics used by enterprises in the production of radiation protective clothing is a national standard.

Huang Jianhua said that in recent years, the relevant national departments have done a lot of work in the standardization of radiation protection textiles, and many related standards have been worked out on yarns, fabrics, test methods, occupational radiation protection garments and so on. These standards have become the main specifications of enterprises in the radiation protection industry in product design, R&D, and production.

Why do radiation suits and national standards cause controversy? Huang Jianhua said that it is mainly due to the public’s poor understanding of national standards that can lead to misunderstandings.

It is reported that in December 2009, China only introduced a "microwave shielding protective clothing" recommended standards, there is no mandatory national standards for the entire radiation protection products.

Huang Jianhua said that the radiation protection industry is an emerging industry. The national standards of any industry are the same as the growth of an industry and will take a long time to complete. The development of each industry is first developed, followed by national standards. National standards are not easy to come by.

It is understood that there are nearly 500 standardization technical committees under the jurisdiction of the National Standards Committee. To formulate national standards for radiation protection suits for pregnant women, some basic standards, method standards, and safety standards must be used, and these standards belong to different standardized technologies. The committee is responsible for the formulation.

In other words, when all these standards are put together, the national standards for radiation protection for pregnant women can be formulated. According to industry sources, it may take three years if these standards are to be collected.

According to the standard grades, China's standards are divided into national standards, industry standards, local standards and corporate standards. The National Product Quality Law states that any product produced by a company must have standards. If a company produces a product that does not currently have a national or industry standard or a local standard, the company must establish a corporate standard and go to the quality inspection department of the place of registration for the record. If the products produced have national, industry or local standards, companies can also set corporate standards and produce them according to corporate standards. However, the quality standards of products in corporate standards are higher than national standards. In other words, national standards are the highest level but require the lowest standards.

Huang Jianhua said that pregnant mothers can rest assured that because in the anti-radiation maternity dress industry, companies have their own corporate standards, and the current national and industry standards are used in the testing of key indicators. If the indicators such as PH value and formaldehyde content are tested according to GB18401-2010 "National Basic Safety Technical Specifications for Textile Products", the shielding effectiveness of fabrics shall be tested in accordance with SJ20524-1995 "Measurement Method of Material Shielding Effectiveness", and the industry requires the manufacturer to conduct quality inspections. Department for the record.

According to Gu Hongyu, a member of the National Garment Standardization Technical Committee, at present, the national standards for the detection of radiation suits are still being worked out. The relevant departments have not yet quantified relevant data and indicators. However, some people on the Internet say that radiation protection suits are not useful, and they must show themselves. The basis for the coming.

In Gu Hongxuan's opinion, radiation protection clothing has a certain role, but in the end how many effects can be achieved, how much radiation can be prevented, 100% radiation protection is absolutely impossible, just like UV protection, this protection is relative Of course, counterfeit pregnant women radiation suits are certainly not protective.

However, to make clear the differences between these standards, it is indeed difficult for consumers. All parties call for: Can special handling agencies accelerate the introduction of radiation-proof national standards?

The State Authority Inspection Department spoke: Usefulness is positive, but only how much is attenuated

Shanghai Metrology and Measurement Institute is one of the authoritative agencies in the current radiation protection fabric testing institute. As the Secretary-General of the National Electromagnetic Shielding Materials Standardization Technical Committee and Chief Engineer of the Shanghai Institute of Metrology and Measurement Technology, Lu Fumin said: “Pregnant women have a certain role in radiation protection service”.

According to Lu Fumin, they had previously conducted anti-electromagnetic radiation tests on many brands of pregnant women's anti-radiation suits on the market, including straps, vests and other styles, and found that radiation protection suits on the market can block most of the electromagnetic radiation.” “Of course, It is difficult to achieve 100% radiation protection. Even if the attenuation reaches 99%, 1% cannot be blocked. During the trials, we found that pregnant women's radiation protection suits are mainly to protect the mother's heart and belly parts (ie, where babies are located), and the effect on the rims is weak. Moreover, the protective effect is closely related to the fabric and style of the clothing. ”

Maternity market quietly warmer

Although the anti-radiation clothing industry suffered heavy losses in the early misinformation, even at the early stage of the incident, some shopping malls considered withdrawing the counters. However, because no country department has issued a directive, it is known that the market misinformed. At present, the market situation has been quiet. Warmer.

Zhao Pu, chairman of October Mommy said that product quality is our greatest concern, as early as two years ago, October Mommy maternity dress and radiation suits passed the national IS09000 and ISO14000 international quality management system certification, and we It is the only maternity dress and radiation protection clothing franchise manufacturer designated by the World Expo. We haven't been affected much by this argument. Our brands are mostly high-end consumers and they have their own judgment.

It is reported that in October Mommy’s radiation protection suits use traditional wire fabrics, silver fabrics and silver ion fabrics. The selected radiation protection fabric fabrics have national implementation standards, and October Mommy will batch The fabrics were sent for inspection and tested by the testing center in the General Administration of Quality Supervision and filed with the relevant national authorities.

Xu Rugen, chairman of Shanghai Tianxiang Industrial Co., Ltd., also stated that as a company, we should regard this matter as a driving force for the development of the enterprise. First of all, for the product, as the company, the product must be more stringent, only to the consumer. Responsible and responsible to society, your product can survive for a long time.

Tim Xiang CEO Xu Taofang: At present, after the market has been turbulent for half a month, it has stabilized and the pregnant mothers are back at the counter. However, some people will bring some problems and we will report on quality inspections and industries. The expert’s statement came out and everyone had no doubts, and as a brand enterprise, in fact, after our clothing enters the mall, the national quality inspection department also conducts regular spot checks.

The reporter met several consumers who were buying radiation suits in stores such as Mommy, Tian Xiang and Qi Ni in October. Their answers showed the consumer's attitude toward radiation protection clothing.

Zhang **: I wore anti-radiation clothes when I was pregnant with the first child. I feel safer for me and my baby.

Wang **: The current working environment has a lot of computers and the radiation is relatively large, so wearing radiation protection clothes is still necessary.

Song **: When colleagues were pregnant, they bought radiation-protective clothing. Now that they have only one child, they hope to have a healthy child in the future.

Radiation incidents continued to subside for several days, and people in the industry appealed that Chinese consumers are extremely sensitive to consumer safety. We need scientific and rational consumption, and the state authorities must promptly clear up relevant issues and clarify relevant matters in a timely manner. After all, Consumers are not professionals. We must try to prevent consumers from being plagued by incidents of consumer safety.
