On June 18th, the "Hongmu" (GB/T 18107-2000) national standard revision start-up meeting was opened, and the revision of the national standard "Redwood" was launched. It is understood that the improvement of the tree species and the method of judging the redwood in the current standard has become the focus of this revision work. In addition, the redwood species listed in the appendix to the CITES Convention are also expected to be included in the revised standard in order to regulate the trading of redwood trade. In the discussion of the preparatory meeting of the drafting group, corporate representatives and academic experts are cautious about increasing or decreasing the coverage of mahogany trees. The method of judging the mahogany may become the focus of this standard revision.
The industry recommends careful adjustment of redwood species
It is understood that the current national standard "Redwood" (GB/T 18107-2000) was released in May 2000, and it has been 13 years since. According to Yin Yafang, Secretary General of the Redwood Branch of the China National Forest Products Industry Association, the revised proposal was submitted in May 2012. It is expected to be completed and approved in December 2014. According to reports, the standard revision plan is aimed at five aspects: improving the species of redwood covered trees, improving the determination method of redwoods, supplementing the redwood species regulated by the CITES Convention, supplementing the microstructural maps of the three species in the current national standard, and the Latin names of some tree species. Errata.
Among them, the improvement of the range of redwood species has attracted much attention. In the current standard, there are 33 species of redwood species defined. Representatives and experts involved in the discussion said that the scope of the redwood species should be changed with considerable caution. Fang Chongrong, secretary-general of Zhejiang Flooring Association, said that the range of redwood species can only be fine-tuned, and it is not suitable for large-scale increase or decrease; Feng Xinhua, manager of the Redwood City Hall, said that in the eyes of consumers, “Redwood†furniture is a high-value commodity, tree species. Once in the mahogany, consumers are willing to pay for it, the market has a great impact, so be very careful.
According to Jiang Xiaomei, a researcher at the Institute of Wood Industry of the Chinese Academy of Forestry, the increase and decrease of redwood species has always been a sensitive topic. There are currently three voices on this topic in the market. She said: "One is from the collecting world, only three of the 33 species are considered, and other tree species should be deleted. Another view is that the tree species specified in the current national standard have been recognized by the market, and adding trees will cause confusion; There is a view that the more the redwood species, the better, so that the redwood resources will increase accordingly, and the price will also decrease. In this case, it is more necessary to listen to opinions widely. It should not be blindly adjusted."
Redwood determination method is valued
The reporter learned that in the discussion of the preparatory meeting of the drafting group, the determination method of mahogany became the focus of discussion. It is reported that in the current national standard, four prerequisites for judging whether it is a redwood species are specified: one is whether it belongs to a specific genus in plant analytics; the second is the timber structure; the third is the air dry density; the fourth is the heartwood color.
Zhu Ping, secretary-general of the Hongmu Professional Committee of the Shanghai Timber Industry Association, said that the characteristics of the judgement come from the stored samples. Because the air-dry density and structure of the wood have a certain range of variation, it is not excluded that the tree species are consistent but the wood structure does not meet the standard, and the human factors exist. Larger, how to quantitatively and qualitatively determine the redwood species should be the focus of the standard revision.
Whether the redwood species is judged accurately is directly related to the trade of mahogany raw materials and the value of mahogany products. It is understood that at present, domestic academic institutions and testing institutions only confirm the genus or class of redwood species (based on 8 categories in the standard). In the market, the price difference between the same species of different species is large. For example, Zhu Ping said: "In the case of broad-leaved Dalbergia, the price produced by India can be four or five times higher than that produced in Indonesia. Even the same species, due to different production environments, are divided into different levels. With this standard, the empty space is sold by shoddy."
â– Difficulties in judging
Tree species identification is a world problem
Whether wood testing can be specific to “species†is related to specific economic interests. How to make the current mahogany standard more practical and operational has become the focus of attention. At present, the industry still has a discussion on the scientific identification of wood species. Jiang Xiaomei said that there are indeed realities in which the wood structure of different tree species is similar and cannot be distinguished. Tree species identification technology is also a worldwide problem.
Yang Guxuan Furniture Co., Ltd. Marketing Director Yang Jing and other business representatives suggested that when importing and exporting mahogany wood, it is necessary to register in the place of origin, and customs declaration materials are generally more difficult to fake. If relevant procedures can be formulated, the real information registered in the place of origin will be borrowed into the domestic circulation link, or the problem of posing as a fake for the tree species will be solved.
Test samples and the whole family have access
The inspection of materials used in mahogany furniture will also be a problem faced by this standard revision. It is understood that the current detection of mahogany furniture is often based on sample testing methods. Many experts said that the testing agency is only responsible for the test results of the samples, but this does not mean that the whole piece of furniture uses trees.
For example, the appearance of sapwood in a certain part of the furniture is inevitable. According to Zhu Ping, in the current "Dark and expensive hardwood furniture standards", the mahogany furniture exclusion table and load-bearing parts are specified. The sapwood area on the surface of other parts and components cannot exceed 10% of the surface area of ​​the parts. It is not completely banned. Use sapwood. If the sapwood is detected, the merchant will be responsible for the quality of the entire piece of furniture, which is not reasonable. Therefore, how to scientifically select the mahogany furniture testing samples and take the mahogany testing method and the mahogany furniture testing method is the problem that the industry calls for to solve.
The test results are not uniform
Due to the defects of the current detection methods, there are also factors that are artificially identified. In the redwood detection industry, the phenomenon that the test results are not uniform is relatively common. Zhu Ping said: "I have seen some mahogany manufacturers and buyers. In order to prove that their wood is a certain species, they have changed several inspection agencies and can really get the results they want. Some testing methods Simple and not standardized, the results are not credible."
Qi Dongqun, deputy secretary-general of the Redwood Branch of the China National Forest Products Industry Association, said: "When the results of the same level of testing institutions are different, if there is a corresponding judicial appraisal procedure and a final decision by an authority, it will be more appropriate to reduce the appraisal. The result is a different chaos."
â– Industry voice
Improve standard operability
â—Jiang Xiaomei, Researcher, Institute of Wood Industry, Chinese Academy of Forestry
An important purpose of this standard revision is to improve the operability of the standard. Many companies have told us that this standard is formulated for professional industry players and requires companies to guide, educate consumers and promote standards. For example, many people in the mahogany market and the name of Chinese literature do not understand, and even some industry experts often consult. In this revision, this is also the focus of our consideration.
I hope that the measurement method is more scientific
â—Zhu Ping, Secretary General of the Redwood Professional Committee of Shanghai Timber Industry Association
The "Redwood" standard plays an important role in the entire mahogany industry. From export trade to downstream mahogany products, there is a great relationship with the determination of mahogany wood. It is hoped that this revision will make the determination method of mahogany more quantitative and scientific, reduce the pressure of honest enterprises in the industry competition, purify the market, and make consumers more understandable.
