The European Tyre and Rubber Manufacturers Association (ETRMA) recently expressed concern about the enforcement of restrictions on polycyclic aromatic hydrocarbons (PAHs) in tires stipulated in the REACH Regulation. ETRMA had previously released a second round of test reports on tires within the EU. The report showed that the current levels of PAHs have not improved compared to the restrictions. It is reported that the results of the first round of survey were published earlier this year. In both surveys, it was found that 10% of the test tires did not meet the REACH regulation PAH limits. Therefore, ETRMA called on the European Union to strictly enforce law enforcement on PAHs limits. ETRMA had previously submitted the results of the report to the European Chemicals Agency's executive forum, but law enforcement authorities in various countries have not taken much practical regulatory action. Currently, only Germany has adopted specific restrictions on PAHs in tires. Germany once tested the tires and asked distributors to recall two tires that did not meet the requirements. Etrema Secretary-General FaziletCinaralp also pointed out that many member states did not use the European RAPEX system to report on the tire conditions on the market. RAPEX should be one of the EU tyre industry's implementation of REACH restriction supervision to ensure that tires meet the requirements. The important way.
From April to September 2011, during the collection of the second tyre sample, ETRMA spent 260,000 Euros and will focus on different types of tyres. The final sample was 94 tires from 50 plants in 11 countries in the EU market, a total of 51 brands, of which 31 were not in the first round of the test list, but the survey found no difference with the results in mid-May 2011 , Eligibility has not improved. There are several unqualified brands that have been rated as unqualified in the first round of testing. In addition, there is a Chinese factory, five kinds of tires under four brands, including car and truck tires, after testing found that the PAH content exceeds the limit. ETRMA stated that the ultimate goal of this survey is to appeal to consumers and market watchdogs to take appropriate actions to prevent unsatisfactory tire imports. In addition, FaziletClinaralp said that the current regulatory measures are too lax, which is unfavorable to the implementation of EU regulations. For example, there is a lack of strict supervision on the tire's fuel efficiency label and other important parameters. Therefore, starting in November 2012, the EU's new labeling directive 2009/1222/EC will take effect, which will require manufacturers to exercise strict control over fuel efficiency, wet road adhesion and noise.
Raman spectrum indicates the vibration and rotation information of the substance molecules. Different materials have different characteristic of spectrum from other materials--characteristic peak, which provides fingerprint spectrum for the substance characterization and identification. CNI launched Raman Spectrometer with the features of compact design, high resolution, high sensitivity, simple measurement and operation, can replace the old spectrophotometer and widely used in chemical and biological research, environmental science, jewelry appraisal, forensic appraisal, food/drug safety inspection, geological exploration and many other fields.
