It's not the standard for applying a mask, just an analogy.
Let's talk about "CN95" first. When Huacheng Certification first introduced this concept, the certified products were divided into five grades, with the highest grade being "CN95". Where C stands for British car, and N95 stands for the filtration efficiency grade of air conditioning filter element, that is, the filtration efficiency of 0.3μm non-oily particles exceeds 95%. In addition to CN95, there are different grades such as CN90 and CN80, but because this is voluntary certification, enterprises generally choose the highest CN95 standard for certification.
Tian Cheng, a senior engineer and doctor certified by Huacheng, said in an interview: "The air conditioning filter element certified by CN95 is not directly equivalent to the N95 mask, but judging from the filtering effect of particles with aerodynamic diameter of 0.3μm, the requirements of CN95 for vehicle regulations are indeed close to those of N95 for masks. Therefore, we compare the air-conditioning filter element to the mask of a car, and put quotation marks on N95 class' to distinguish it. It's not the standard for applying a mask, just an analogy. "
As a third-party certification body focusing on automobile and its related industries, Huacheng Certification launched CN95 certification, which is considered as a hot spot by many people. In this regard, Dr. Tian Cheng said that this statement is not denied, but there are also difficulties. In fact, the certification of air-conditioning filter elements has been planned for a long time, not on a whim. However, the air-conditioning filter element is a relatively unpopular component, which is rarely concerned at ordinary times, but it is closely related to people's life and health. In order to catch up with the epidemic, both manufacturers and consumers have paid unprecedented attention to the health in the car. On the one hand, the introduction of this certification is to respond to the social demand for in-vehicle health, on the other hand, it is also promoting the standardization and high-level development of the air-conditioning filter market.
Vehicle "antivirus level" itself is a false proposition.
Regarding the question of whether vehicles can be "anti-virus", Dr. Tian Cheng said that when considering the formulation of vehicle protection indicators, it mainly targets harmful substances such as PM2.5, PM 10, droplets (the main carriers of viruses) and bacteria. Among them, the aerodynamic diameter of the droplets is 1- 10μ m > 0.3μ m, which can "for smaller particles such as aerosols and virosomes (about 0. 1μm) less than 0.3μ m, it is not within our defined vehicle-level protection range, but even so, the certified products can still be filtered to some extent.
The virus does not spread in a single way, but more from person to person in the form of droplets, which is why the N95 mask is not used to prevent the virus. Qipai Media's comments on this incident-From the perspective of epidemic prevention, we don't need "N95" class cars. At present, most cars on the road have been able to meet the needs of isolating viruses. The so-called N95 air purification system is not aimed at viruses. There is no virus in every link of life, so as to ensure that it will not be infected, and the car is only one link-and the risk of this link is the least.
It can be said that paying attention to the "anti-virus" of vehicles is a false proposition. Except for the filtration and protection level of air conditioning filter element, the use of vehicles is completely different from the so-called mask protection. For example, daily opening and closing of doors and windows will change the tightness of the car, and it will also have an impact when the car stops or the air conditioning system of the car has not started. Therefore, we should pay more attention to the air quality inside the car.
It is an improvement from the endless stream of "N95 protection" to the standardized "CN95 certification".
As of March 24th, CN95 certification project has completed a total of 40 certification units 100, of which 80 meet the requirements of CN95, with a coincidence rate of about 57%, involving more than100 models. From the trend of statistical results in each week, the overall performance level of the tested samples is gradually improving, but it has not been improving all the time, but has remained at around 60%, and many samples still cannot meet the highest standards.
The first batch of 9 certified enterprises are all vehicle manufacturers, mainly independent brands, including Geely, FAW, BAIC and BYD. And joint venture car companies such as Beijing Hyundai; In the second batch, more joint venture car companies appeared, and at the same time, air conditioning filter manufacturers joined; In addition, Huacheng Certification recently issued a product certification certificate to the automotive air conditioning filter produced by Volvo car supplier MANN+HUMMEL, which is also the first international certificate of CN95 series. Dr. Tian Cheng said that due to the impact of the epidemic, it is difficult for many international enterprises to carry out this certification, but the certification project has gradually been accepted and recognized by them.
According to incomplete statistics, there are nearly 1,000 domestic automobile air conditioning filter manufacturers. Because there is no national compulsory inspection, the quality of products circulating in the market is uneven, and the filtration efficiency is also very different. After this certification, CN95 certification has been regarded as a necessary condition to support the existing vehicle enterprises to supply air conditioning filter products. At the same time, many car owners are also consulting to replace CN95 air conditioning filter. Dr. Tian Cheng said that although this is voluntary certification, through such market selection, the survival of the fittest will be gradually realized. "As a consumable part, the air-conditioning filter element actually belongs to the automotive aftermarket product. We are also promoting cooperation with some e-commerce platforms, and adding some special logos to certified products to facilitate consumers' purchase. "
At present, many car companies have joined CN95 certification as a "selling point" when promoting their products. As far as publicity is concerned, it is an improvement in itself from the constantly emerging slogan of "N95 protection" to the standardized CN95 certification. Dr. Tian Cheng said that in view of the problem that some manufacturers exaggerate publicity, at the same time of product certification, they will also explain the technical requirements of certified products to enterprises, and suggest standardizing publicity content to avoid misleading consumers; At the same time, this certification is not permanent, but has a time limit, usually three years, and will be re-certified according to the latest standards after expiration; In addition, they will regularly check the certified products according to market feedback and play a supervisory role.
"North-South Cooperation" is the first vehicle-level certification, and this CN95 is not the same CN95.
Although the certification of air-conditioning filter element solves the problem of air-conditioning air intake cleaning, the health inside the car actually involves many aspects such as odor and noise inside the car. Moreover, when the manufacturer applied for CN95 certification, it provided the product model of air-conditioning filter, which did not involve specific models, and consumers did not know when buying a car. To this end, Huacheng Certification announced on February 28th that CN95 certification of air-conditioning filter element was taken as the representative and starting point to evaluate the health and safety in the car, and the concern about the health and safety in the car extended from the air-conditioning filter element to the cockpit of the whole car. At the same time, Kerry Certification (located in Chongqing and affiliated to China Automotive Engineering Research Institute) has also launched the "Intelligent Healthy Cockpit" certification, which is divided into "Healthy Cockpit" and? Two certification directions of "intelligent cockpit".
Huacheng Certification and Kerry Certification are third-party certification institutions under China Automotive Technology Research Center (Tianjin) and China Automotive Engineering Research Institute (Chongqing) respectively. Both of them have introduced the "automobile health" certification system. Although they have good intentions, they are easily confused and some repeated tests are inevitable. In order to reduce the burden on enterprises and better support enterprises to resume work and production, Huacheng Certification and Kerry Certification cooperated for the first time. On March 27th, they announced that they would unify their certification projects of "CN95 Healthy Cockpit" and "Intelligent Healthy Cockpit" into "CN95 Intelligent Healthy Cockpit". It is understood that the two sides will jointly promote the mutual recognition of "CN95 Smart and Healthy Cockpit" certification, and enterprises can freely choose certification institutions. In the later stage, the two sides will also jointly implement the certification of "CN95 Intelligent Health Cockpit" through the established certification alliance, testing institutions, enterprises and media.
The future "CN95" is a completely different concept. If N95 sets the highest standard in the mask industry, then "CN95" will become synonymous with health and safety in the car. For consumers, it is more reassuring to buy N95 masks that "one mask is hard to find"; It is also a kind of peace of mind to buy CN95 healthy cockpit certified vehicles. After all, many car owners have long hated all kinds of strange smells on new cars and are afraid of electromagnetic radiation.
Not long ago, J.D. Power (Di Jun) released a survey report on the influence of COVID-19 epidemic on consumers' willingness to buy cars. The top three factors that consumers in China consider when buying a car are quality (82.3%), safety (69. 1%) and performance (68.6%), but the epidemic situation makes the air safety and health inside the car another important factor (46.5%). In this context, the certification of indoor air safety and health can be said to be a "just need" to promote the overall improvement of automobile products in the field of health and safety.
From questioning to recognition, from domestic to international.
"N95" is not a proper term, not to say that it can only be used for masks, but it conveys a very high standard. The expansion from CN95 certified air conditioning filter to vehicle cockpit has also set a benchmark in the field of automobile health. The birth of a new thing will inevitably have different voices, but some malicious interpretations and slanders are also unfavorable to the development of the industry.
At the beginning of CN95 certification, auto filter manufacturer Kedebao publicly questioned it, but later clarified the misunderstanding, affirmed the role of CN95 certification in promoting the development of automobile air conditioning filter industry, and said that it would continue to cooperate with Huacheng certification in the future to conduct in-depth discussions on the improvement of certification rules and the revision of industry standards. In the process of internationalization, in addition to international enterprises applying for certification, Huacheng certification is also related to T? V. Sü ddeutsche Zeitung Group (T? V Nande "), signed a long-term cooperation framework contract for CN95 automobile air conditioning filter product logo certification service. Enterprises only need to apply once, test once, and pass the audit, then they can obtain the CATARC mark certification certificate and T? South Germany China logo certification. This time with t? V. German-South cooperation is an important measure to promote the internationalization strategy of Huacheng Certification.
From questioning to recognition, from competition to cooperation, from domestic to international ... CN95 certification, which was born in a special background, has taken a unique development path. It can be said that "CN95 certification" is not a hot spot, but a popular feeling. Behind the hot spots are the needs of the market and the wishes of the people. If such a "hot spot" can let more consumers know the importance of a healthy automobile environment and promote manufacturers to develop technologies in this area, it will be worthwhile!
