China is a major children toys manufacturer in the world. Every year, about2/3toyson sell are made by China. Recently years, children toys were recalled frequently from themarket as the safety problems. These recalls course people do not trust the quality and safetyof children toys made in China. Most of the countries publish laws, regulations and directiveson the safety of toys. And these laws, regulations and directives are implementation as stricteras they can.At now a day, the children toys standards mostly concern on the safety, and the safetynormally include Mechanical and physical properties, flammability and toxic chemicals andelectric toy safety. The toxic chemicals in toys mainly include heavy metals, phthalates,formaldehyde and so on. Heavy metals is toxic in heavy metal Poisoning, like headachy,difficult to breathing, hair loss, numbness, pain in bone, injured in neuropathic and innerorganic of body or serious one, heavy metal can make the people poisoning death. Phthalatesis on of environmental hormones. It will strong corrosive effective in skin, mucousmembranes and influence the body central nervous system or damage the liver, kidneys, andalso case the Precocious Puberty. Formaldehyde has a strong cause carcinogenic as mostreports as it is.In order to comply with the requirements of these laws, regulations and directives,testing is a necessary tool to confirm the compliance. Chinese toy manufacturers and tradershave invested lots of manpower and money to carry out kinds of testing and inspection. Fortraditional test methods, they cause long test time, expensive facilities and lots of work onmaintenance. These costs cannot afford by most of the companies. So that a simple, quick andmore economic (low cost) test method research is important and significancy for Chinese toysindustry.This paper is studying on the international toys safety regulations, analysis the toxicchemical test new methods and research on application of XRF determine the heavy metals,FTIR scan analysis on the phthalates in PVC and Spot test method usage on formaldehyderelease on textile. The study includes the method validation, practical and profitabilityprinciple, offering a valuable and practical testing compliance solution to china toymanufacturers and traders, to reduce their test cost, decrease the testing time. The newlyestablished methods are simple, fast, economic and easy to popularize. It has a very good andvaluable on the real application.
