information in the national coating industry information. In recent years, home decoration has become a noticeable consumption hot spot. In the interior decoration, interior wall coating has become the main interior wall decoration material. However, a small amount of volatile organic compounds (VOC), benzene compounds, trace formaldehyde and toxic and harmful metal elements contained in interior wall coatings are harmful to human health, which has attracted great attention of relevant departments. The national compulsory standard GB 18582 limits of harmful substances in interior decoration materials and interior wall coatings, issued by the National Standardization Administration Committee, has been enforced since July 1st, 2002. With the progress of technology, the improvement of product quality and the green orientation requirements of market consumption, the original standard has made it a substitute in preschool education and teaching, which can not meet the needs of the market for the global maximum limit of American steel cost, a harmful substance in interior wall coating. To this end, the National Technical Committee for standardization of paints and pigments revised it in 2006 and will soon issue it for implementation. The newly revised standard not only appropriately raised the limit requirements for hazardous substances, but also increased the limit requirements for benzene compounds that consumers are more concerned about. More importantly, it modified and improved the relevant test methods, especially for volatile organic compounds. People worry that the performance of fiber composite polymers will be damaged after long-term exposure to ultraviolet light, Instead of the current method of removing water from total volatile matter, the direct test by ergodic curve gas chromatography is used to make it consistent with the current international and domestic test methods, so as to reduce the test error as much as possible

in order to make relevant coating manufacturers, users and supervision departments at all levels timely understand the latest contents of the standard and master relevant testing methods, the National Technical Committee for standardization of coatings and pigments and the National Center for quality supervision and inspection of coatings decided to hold a training course on the publicity, implementation and operation of the newly revised standard GB 18582 in Changzhou in may2007. The training course will employ the main drafters of the standard and experts of relevant test methods to systematically explain and conduct practical operation training in terms of the purpose and significance of the standard revision, scope of application, limit requirements, principle and operation steps of the test method

this training will enable students to understand the latest content of the standard and master the testing skills of relevant testing items through explanation, on-site actual operation and Q & A. Main teaching contents include:

introduction to standard content

determination of volatile organic compounds (VOC) by gas chromatography Content method introduction and practical operation training

method introduction and practical operation training of determining the content of benzene compounds by gas chromatography

method introduction and practical operation training of determining the content of free formaldehyde by ultraviolet visible spectrophotometer

method introduction and practical operation training of determining the content of soluble heavy metals by atomic absorption spectrometry
