  The Amazon CPC certificate is a certification document indicating that children's products sold in the US market must comply with the requirements of the US Consumer Goods Safety Improvement Act (CPSIA) and should be provided by the manufacturer or importer. The CPC certificate proves that the product has passed the necessary tests and complies with all applicable child product safety rules. The CPC certificate test items usually include: Physical and mechanical testing Flammability test chemical test Labbel and warning language tests Electrical safety test Radiation test The CPC certificate must contain details of the product, test results, applicable regulations and standards, and contact information for the manufacturer or importer. If the product does not have a CPC certificate or the certificate does not meet the requirements, Amazon may prohibit the product from being sold on its platform. www.uni-lab.hk/ hofferlau@uni-lab.hk

  Tensile Testing Machines is a kind of instrument used for measuring the geometric parameters of materials (metal, plastic, fiber, etc.) and static dynamic mechanical characteristics under tensile load. Tensile testing machines through the opening of the sample across (to determine the size and shape according to the standards or specifications), with the tensile strain stress into meaningful numerical results, in order to accurately judge and analyze the tensile properties of various materials. Now let's take a look at the steps of using the Tensile Testing machine The use steps are as follows: Preparation: fix the material sample to be tested on the test machine, and adjust the fixture and sensor of the test machine. Set test parameters: set mode, speed, range for testing. Start the test: Start the test, the test machine will apply force to the material, and record the test data. End test: After the test, stop the operation of the test machine and save or print the test data. Da...

  ASTM is a mandatory certification of toy testing in the United States. Whenever the toy products are exported to the United States, they need to do ASTM testing. ASTM F963 Is a toy testing standard developed by the National Department of Standards of the United States. The latest version is ASTM F963-17 and has become a mandatory standard on September 01,2017. American Toy Safety Test ASTM F963 Standard details: 1. Supplement some references to food and cosmetics, mainly standard methods for microbiological testing, CFMethods M-1, M-2, M-3 and M-6; USP Volume 35 Methods 61, Methods 62 and Chapter 1231; and FDA's Microbiological Analysis Manual. 2. Supplement the key instructions on the inadvertent omission of ejection toys in 2016 edition, indicating that KED (kinetic energy density) is only suitable for ejection and arrow toys with kinetic energy above 0.08J. 3. Revision of some relevant test details such as low-power circuit in electric toy testing. 4. Add and make it clear tha...
