The national standard is a normative standard set for a certain industry and a certain commodity nationwide. For the big home industry, the release or execution of each national standard is quite noticeable. Recently, a number of upcoming national standards have received much attention. The revision or introduction of these national standards will have far-reaching impact on industrial development, product upgrading and industry integration of related industries.
The formaldehyde emission limit of the board is more strict
Standard name: GB 18580-2001 "Limits of formaldehyde release 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 approval stage.
New standard implementation of various furniture such as sheet soft bed sofa
Key points: This standard specifies the test method for the formaldehyde emission limit value of different product types, and divides the product into two grades E1 and E2 according to the release amount of formaldehyde. Among them, the E1 level can be used directly indoors, and the E2 level must be used for interior treatment.
The well-known plates and sheet products, such as particleboard, fiberboard and laminate flooring, are all specified in this standard. The formaldehyde limit value of many related product standards is also consistent with this standard.
Since the implementation of the standard for many years, after the development of the industry and the promotion of the merchants, many consumers have already known that the E1 standard is “≤1.5mg/Lâ€, which has become the “lowest limit†for the emission of formaldehyde in many finished products such as flooring and cabinets. standard".
Many brands have also conducted in-depth research in this area. In the market, formaldehyde emission is less than 0.5mg/L or even “zero formaldehyde†products are emerging one after another. Merchants and consumers pay more attention to the indoor environment after renovation, which promotes the revision and upgrading of this standard.
Expert opinion: According to Duan Xinfang, secretary general of the National Standardization Technical Committee for Wood-based Panels, this standard is in the process of revision and needs to be approved for release. Therefore, the specific revisions are not disclosed. But what is certain is that the formaldehyde release limit requirement in the new standard will definitely increase. He said: "According to the current standard, the E2 level is the bottom line. The new standard will increase the formaldehyde release limit value. The specific method is being discussed and agreed. The key to reducing the formaldehyde emission of artificial board is to improve the quality of the adhesive. In order to meet this requirement, the enterprise Production technology, production equipment, and testing equipment must be updated. Once the revised new standards are implemented, it will prompt the industry to enter a rapid reshuffle stage."
Soft bed sofa can be tested without damage
According to industry insiders, the limited regulations on harmful substances such as formaldehyde and TVOC for sofas and mattress products, "Limits of harmful substances in soft furniture sofas" and "Limits of harmful substances in mattresses for soft furniture" have been drafted and are currently awaiting review. Announced. These two standards stipulate the limits of hazardous substances and stipulate the test methods. After the implementation of the standards, sofas and mattresses are expected to achieve non-destructive testing.
Standard Name: GB 18584-2001 "Limited Quantity of Hazardous Substances in Wood Furniture for Interior Decoration Materials"
Revision process: The current standard is implemented on January 1, 2002, and revised in 2011. The revised version has not yet been officially announced.
Key points: In the consultation draft published in 2011, the limit requirements and experimental methods for formaldehyde emission in wood furniture were revised, and the limit requirements and test methods for benzene, toluene, xylene and TVOC were added, and the migration was revised. Test method for elements. Among them, the test methods for harmful substances such as formaldehyde are the most concerned.
In the current standard, the “dryer†method is used for the determination. In the exposure draft, the climate chamber method is used. The dryer method is to cut the furniture into small pieces for testing, and the climate chamber law is to place the furniture in the climate chamber. The purpose of evaluating furniture is achieved by detecting the air quality of the climate chamber under simulated conditions.
If the standard is revised as such, the test method will be closer to the actual use environment of the furniture, the test results will be more scientific and rigorous, and for the consumer, the cost of detecting the furniture will also be reduced. In addition, this test method is aimed at a piece of furniture, not a single piece of the sample, the result is more comprehensive and reliable.
Expert opinion: Zhu Changling, chairman of the China Furniture Association, said that the final version of the standard revision has not yet been announced. Whether the “non-destructive testing†expected by consumers can pass is not known, but relevant suggestions have been put forward in the draft for comments. The final result will be subject to the information published by the National Standards Committee.
Has been announced:
Children's bed standard
Standard name: GB 29281-2012 "Safety requirements for playpens and similar use cribs"
Specific content: This standard was officially released on December 31, 2012 and will be implemented on May 1, 2014. The standard specifies the important information such as the structure, strength, warning signs, installation instructions and toxic and hazardous substances of similar structural cribs. Among them, Chapter 4 of the standard is mandatory, including limiting the maximum amount of migratable elements in the material. In the Structure section, holes, openings and gaps, edges, points, corners, moving parts, similar to furniture, Details such as the folding locking mechanism are specified, and the necessary warning words are also specified on the packaging, marking and instructions for use.
Scope of application: Children's beds and similarly-structured household items, as an important category in children's furniture, their safety performance has also received much attention, and sometimes small details that are not noticed may become fatal injuries to children.
For example, the product has sharp edges and tips; the product size does not meet the requirements, there is a danger of the baby crawling out of the crib; the distance between the side fences of the wooden children's bed is too large, the child may stick the head out from the middle; Excessive use of toxic and hazardous substances in main and auxiliary materials such as wood and textile fabrics is harmful to children's health.
Consumer reminder: buy children's beds, mainly to see three aspects, first, the material of the bed, whether it meets environmental standards. Including the use of wood, mattress textiles, etc., by product specifications or test reports to identify; Second, by eye-hand touch, the surface of the bed is smooth and no burrs, especially where the child's skin is in contact; third, The structure of the bed, for example, is it strong? Is the height suitable for children? Is there a place where it is easy to stab and touch?
Mechanical properties determine the safety of furniture use
Standard name: "Mechanical Performance Test of Furniture"
Specific content: "Furniture Mechanical Performance Test" The new national standard has table strength and durability, chair and stool stability, chair stool strength and durability, cabinet stability, single bed strength and durability, table stability The six standards have been revised in previous versions. These standards belong to the general basic standards of testing methods. The mechanical properties are determined according to the use and carrying of objects by consumers. No matter what kind of materials are used for production, it must be tested by the general technical standards of mechanics. Among them, the stability of the cabinet has been modified and supplemented. For example, the stability standard of the cabinet has modified the stability test of the shelf and the loading stability when the movable parts of the non-fixed cabinet are opened. In terms of table strength and durability, the desktop horizontal static load test method when the table top is irregular shape and the desktop horizontal endurance test method when the table top is irregular shape are added.
Scope of application: Whether the furniture is durable and can carry multiple objects, it can not be judged by the thickness and feel of the board. It must be tested by the general technical standard of mechanics. Usually, when the furniture is inspected and accepted, the stability, stiffness, strength, durability and other factors of the furniture product will be investigated. If the mechanical properties fail to meet the standard, it will directly affect the service life and safety of the furniture.
The mechanical properties of furniture are one of the main unqualified items of local and even national sampling. According to industry insiders, when testing furniture, it has been found that there are problems in strength, durability, stability, etc., which are related to the safety of consumers. In the news media reports, this item is often unqualified.
Consumer reminder: consumers should pay attention to the proportion of furniture when coordinating, try not to choose furniture with too large proportions, should pay attention to furniture materials, pay attention to the thickness of furniture plates to match the use of functions, but also pay attention to design details, such as Whether the design of the drawer slide is loose, and the inclination of the backrest of the chair is reasonable. When consumers choose furniture, they can rely on the senses to try, such as shaking the furniture, seeing homes with signs of no looseness, falling apart, or sitting down, relying on the back and making a simple decision.
Other standards:
The most stringent national standard for faucets will be implemented
Standard name: GB 18145-2014 "Ceramic sheet sealing faucet"
Specific content: On December 1 this year, the new national standard "ceramic sealing faucets" will be officially implemented. The current standard was implemented in 2004, and the new national standard was supplemented in many aspects such as water-saving performance and quality of use of the faucet. Among them, the new standard limits the amount of metal contaminants released from the nozzle, and limits the requirements for 17 kinds of metal precipitates such as lead, antimony, arsenic and antimony. Among them, the lead precipitation statistical value (Q) is not more than 5 μg / liter. In addition, water-saving performance and performance have changed. For example, the new national standard has increased the sealing performance requirements of top spray showers and hand shower switches, increased the adhesion strength requirements of plastic substrate coatings, and modified the surface corrosion resistance requirements. This raises the surface quality requirements of the faucet to avoid the appearance of easy color fading and rust.
Scope of application: The faucet is used frequently and has a wide range. In the sampling inspection of the industrial and commercial departments, it is possible to repeatedly see the failure of the faucet detection.
Consumer Reminder: When consumers buy faucets, in addition to looking at product descriptions and test reports, they mainly rely on subjective feelings. For example, the surface of the faucet requires uniform gloss, no pores and oxidized spots; the more the material feels, the heavier the hand feels; during the trial, the swing handle can drive the valve core to feel loose, light, and without blockage. .
Air purifier function will be subdivided
Standard name: GB/T 18801-2008 "Air Purifier"
Revision process: The current standard was implemented on September 1, 2009. The new version of the standard is being revised and is expected to be released next year.
Highlights: Currently, there are three national standards for safety and performance requirements for air purifiers. Among them, GB 4706.45-2008 "Special requirements for safe air purifiers for household and similar electrical appliances" is to prevent consumers from the dangers of electric shock, burns, mechanical damage, fire, toxicity and radiation during use. GB 21551.3-2010 "Special requirements for air purifiers for antibacterial, sterilizing and purifying functions of household and similar electrical appliances" is a national mandatory standard, mainly used to assess whether air purifiers have effective antibacterial and sterilization capabilities, including antibacterial Technical requirements such as rate and sterilization rate. GB/T 18801-2008 "Air Purifier" is mainly used for the evaluation of the comprehensive performance of the air purifier, used to assess the purification capacity of the air purifier, the set of technical indicators are: clean air volume (CADR), purification efficiency, noise , purification life and so on. The corresponding target pollutants are mainly divided into fine particles and gaseous pollutants (formaldehyde, benzene, etc.).
In the current standard, the energy efficiency rating and experimental method of the air purifier are specified. The new standard has improved the technical indicators and refinement test methods for different pollutants, and will provide a basis for consumers to purchase related products. After the revision of the new standard, the evaluation of the purification performance of the product will be more rigorous and scientific, especially for the purification of PM2.5 and formaldehyde removal functions, there will be detailed experimental methods, and the air purifier function on the market will be over-promoted. Will be curbed.
Expert opinion: Wu Jixiang, a professor at Shanghai Jiaotong University, said that air purifiers should be graded according to the needs of the people in use, such as health-care air purifiers for special people 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 the household air purifier are concentrated on the pollutants such as formaldehyde, toluene and other benzene series, PM2.5, and some treatment methods are limited. For example, the side effects of ozone will also be considered.
Masks should also be graded
According to media reports, the "Technical Specifications for Daily Protective Masks" is expected to be published before the end of the year. The standard will cover mask material requirements, structural requirements, labeling requirements, appearance requirements, etc. The main indicators include functional indicators particulate matter filtration efficiency, expiratory inspiratory resistance index, and adhesion index. As a textile, the indicator also relates to formaldehyde content, pH value, microorganisms such as the number of E. coli bacteria, and the total number of fungal colonies. In addition, the new national standard will also classify and classify masks. According to the degree of air pollution, it is divided into heavy pollution application, moderate pollution application, and mild pollution application. According to the characteristics of different groups of people, such as adults, children, and infirm, different breath resistance indicators are set to classify masks.
