What
keyword during the epidemic that? I believe the “N95” definitely count as one. From the outbreak so far, N95 does not just appear on the masks and other protective equipment, it is the emergence on the air filter, air conditioners and even cars. What is more, many car prices during the epidemic has also introduced the so-called “N95 Health Protection car”, leaving the eye-popping it is that there are two bodies come out, respectively, with two sets of standards defined what it meant to “N95 car . ”
BARI Huacheng authentication (hereinafter referred to as “Huacheng”) and Chongqing Kerry quality Inspection certification Center (hereinafter referred to as “Kerry”), is that these two institutions. But unlike a lot of people think that’s what third-rate company, the two companies backing is not small. The former come from China Automotive Technology and Research Center, which has underpinned China Automotive Engineering Research Institute, and two certification bodies have long assumed the domestic automotive and related product testing and certification services of many, one of which includes an internal air vehicle quality.
March 29, Huacheng Kerry and the two announced their’s “CN95 health cockpit” and “wisdom health cockpit” unified certification program as “CN95 wisdom health cockpit” certification, and it has now completed “CN95 wisdom health cockpit” integration and preparation of the first edition of the certification rules. This also means that now concern “CN95 car” become evidence-based, consumers can have a more clear understanding.
It is reported that, in addition to Huacheng and Kerry will continue to develop under the guidance of regulatory authorities and perfect “CN95 wisdom Health outside the cockpit “certification rules, the two sides will also certified the late formation of the Union to absorb testing organizations, enterprises and the media to join together to negotiate the relevant certification. Currently known is that both have been and TV SÜD (hereinafter referred to as “TV NEG”) formally signed CN95 air filter product logo certification service long-term cooperation framework car contract.
As the world’s largest and oldest TV inspection agencies, TV Nande has a leading German technology. The combination of the three is undoubtedly a breakthrough in the domestic agency logo certification mode, in addition to allowing higher reliability than the detection results, but also shorten the duration of certification to increase efficiency certification.
However, although unified standard, but we can not deny CN95 car did not prevent the role of the new crown virus. Compared to the N95 masks, the cabin air filters have different product characteristics, with significant differences in the use of property and product standards. The experimental results show that the so-called percentage can reach 95 (A2 mineral dust) filtration efficiency filter, sodium chloride aerosol in the test only 70 percent filtration efficiency, and N95 masks has a very clear difference. The coronavirus diameter of about 80-120nm, compared with sodium chloride aerosol diameter of 0.3μm taken as a test medium, resulting out of the results are more convincing.
and from the use of the properties of the product, wear a mask and a key role in that snug fit, so you can well isolated from the outside air. While living in the interior while the car can be isolated from the outside world, but because of the switch doors, windows and other acts, enclosed vehicle may also change, moreover virus also may enter the vehicle interior from the gap, so the car closed and masks the closure can not be equated. In addition, the car’s air conditioning filter replacement frequency should be much lower than the mask, just this point can tell the difference between the two.
It is worth mentioning that the one-sided pursuit of high filtration efficiency rating of air conditioning filters, there may be reduce the amount of air conditioning and ventilation, the impact on the service life and maintenance costs of air conditioning filters. Thus, many currently on the market claim to be 95% or more in diameter is 0.3μm particle filtration efficiency models do notA prospective, let alone be able to effectively filter the novel coronavirus.
must first be clear that the concept of CN95 car from a proposal to determine which among the elapsed time is very short you can even say that this standard certification, is born under the background based on the needs of the outbreak. And the unified standard, in addition to a symbol of the spontaneous industry norms outside, but is in addition to the filter, members of the cabin once the overall environmental safety norms. As had previously appeared, questioning the internal parts of the vehicle air quality in general, after this, it is evidence-based, consumer confidence can have a higher standard of reference.
from the contents of the unified CN95 series certification system point of view, it mainly it covers the interior of harmful particulate filter (air filter filtration efficiency), air quality (interior volatile organic compounds, VOC), car smell (odor level), radiation (electromagnetic protection body), quietness (the car noise level), antibacterial (interior surface), a harmless material (contact member may be prohibited substances), car air purification eight active field. The two agencies to get a vehicle to grant “CN95” certification, require the vehicle can pass more than eight tests.
In the long run, as the more complete the certification standards for air quality inside and consumer more and more attention, naturally make more and more car companies pay more attention to the car environment to invest more R & D funding to further improve the environmental conditions inside the vehicle. In fact, generally refer to the original intention of the collision and the current role of test appearance, for consumers, which is not only for the good, and even called a very meaningful thing.
