The introduction of a number of new national standards will promote industrial development

national standards are normative standards formulated nationwide for a certain industry and a certain commodity. For the large home furnishing industry, the release or implementation of each national standard has attracted considerable attention. Recently, a number of upcoming national standards have attracted much attention. The revision or introduction of these national standards will have a far-reaching impact on the industrial development, product upgrading and industry integration of related industries

it is worth looking forward to

the formaldehyde emission limit of plates is more stringent

Standard Name: GB "formaldehyde emission limit in interior decoration materials, wood-based panels and their products"

revision process: the implementation date of the current standard is January 1, 2002, which is a mandatory national standard. The revised standard has now entered the stage of approval

key content: this standard specifies the test method of formaldehyde emission limit values for different product types, and the products are divided into E1 and E2 grades according to the formaldehyde emission. Among them, grade E1 can be directly used indoors, and grade E2 can be used indoors only after finishing

we are familiar with the board and board supplies, such as particleboard, fiberboard, laminate and other decoration products, which all stipulate the formaldehyde emission limit value in this standard, and the formaldehyde limit value of many related product standards is also unified with this standard

since the implementation of the standard for many years, after 1. Connecting the main switch to the power supply and through the industry development and business publicity, many consumers have known that the E1 standard is "≤ 1.5 ㎎/l", which has also become the "minimum standard" for the formaldehyde emission limit of many finished plate products such as floors, cabinets and other commodities

many brands have also made in-depth research in this regard, and the inclined block on the swing arm cannot be violently impacted. In the market, formaldehyde emission is less than 0.5 ㎎/l, and even "zero formaldehyde" products emerge in endlessly. Merchants and consumers pay attention to the indoor environment after decoration, prompting the revision and upgrading of this standard

expert opinion: according to Duan Xinfang, Secretary General of the national wood based panel Standardization Technical Committee, this standard is in the process of revision and needs to be approved for release, so the specific revision content is not convenient to disclose. But it is certain that the formaldehyde emission limit requirements in the new standard will certainly be improved

he said: "according to the current standard, E2 level is the bottom line. The new standard will increase the formaldehyde emission limit, and the specific method is being discussed and agreed. The key to reducing the formaldehyde emission of wood-based panels is to improve the quality of adhesives. In order to meet this requirement, the production technology, production equipment and testing equipment of enterprises should be updated accordingly. Once the revised new standard is issued and implemented, the industry will enter the stage of rapid reshuffle."

the function of air purifier will be subdivided

Standard Name: gb/t air purifier

revision process: the current standard was implemented on September 1, 2009, and the new standard is under revision and discussion, and is expected to be released next year

key content: at present, there are three national standards related to the safety and performance requirements of air purifiers. Among them, GB 4706 "Special requirements for safe air purifiers for household and similar electrical appliances" is to prevent consumers from electric shock, scald, mechanical damage, fire, toxicity, radiation and other hazards during use. GB 21551. "Special requirements for air purifiers with antibacterial, bactericidal and purifying functions of household and similar electrical appliances" is a national mandatory standard. The continuous expansion of downstream utilization is mainly used to assess whether the air purifiers have effective antibacterial and bactericidal capabilities, including technical requirements such as antibacterial rate and bactericidal rate. Gb/t "air purifier" is mainly used to evaluate the comprehensive performance of air purifiers and to assess the purification capacity of air purifiers. The technical indicators set up include: clean air volume (Cadr), purification efficiency, noise, purification life, etc. The corresponding target pollutants are mainly divided into fine particles and gaseous pollutants (formaldehyde, benzene, etc.)

in the current standard, the energy efficiency grade and experimental method of the air purifier are specified. The new standard improves the product technical indicators for different pollutants and refines the test methods, which will provide a basis for consumers to choose and buy related products. After the revision of the new standard, the evaluation of the purification performance of products will be more rigorous and scientific, especially for the removal of PM2.5 and formaldehyde and other functions of the purifier, there will be detailed experimental methods, and the excessive publicity of the function of the air purifier in the market will be curbed

expert opinion: Professor wujixiang of Shanghai Jiaotong University introduced that air purifiers should be classified according to the needs of users, such as health-care air purifiers for special groups such as the elderly, patients, pregnant women and so on. After the revision of the standard, it will be more clear that the functions of household air purifiers are concentrated on pollutants such as formaldehyde, toluene and PM2.5, and some treatment methods will be limited, such as the side effects of ozone will also be considered

furniture nondestructive testing method has attracted attention

Standard Name: GB "indoor decoration materials - Limits of harmful substances in wood furniture"

revision process: the implementation date of the current standard is January 1, 2002, and the revision began in 2011. At present, the revised version has not been officially published

key content: in the exposure draft published in 2011, the limit requirements and test methods of formaldehyde emission in wood furniture were modified, the limit requirements and test methods of benzene, toluene, xylene and TVOC were added, and the test methods of transportable elements were revised. Among them, the test methods of formaldehyde and other harmful substances are the most concerned

in the current standard, the "dryer" method is used for determination, and the climate chamber method is used in the exposure draft. The dryer method is to cut the furniture into small pieces for detection. The climate chamber method uses to place the furniture in the climate chamber and evaluate the furniture by detecting the air quality of the climate chamber under the condition of simulating the use environment

if the standard is revised like this, this test method will be closer to the actual use environment of furniture, and the test results will be more scientific and rigorous. For consumers, it will also reduce the cost of testing furniture. In addition, it is renewable, recycled and recycled resources. This detection method is aimed at a whole piece of furniture, rather than a single sample, and the results are more comprehensive and reliable

expert opinion: Zhu Changling, chairman of the China Furniture Association, said that the final version of the revised standard has not yet been published, and it is unknown whether the "nondestructive testing" expected by consumers can pass, but relevant suggestions have been put forward in the exposure draft. The final result should be subject to the information published by the National Standards Commission
