Chinese Graphite Testing Standards

We use the GB testing standards for our graphite products, which are the Chinese national standards issued by the Standardization Administration of China (SAC), the Chinese National Committee of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

Mandatory standards are prefixed GB for Guo Biao or Guojia Biaozhun, which translates into "National Standard", and recommended standards are prefixed GB/T - for Tuijian, or "Recommended".

GB standards are the basis for all product testing during the China Compulsory Certificate process, commonly referred to as the CCC Mark - a compulsory safety mark for many products imported, sold, or used in the Chinese market.

Our testing standards include:

In addition, our company and its products have undergone an audited verification by SGS - the world's leading inspection, verification, testing and certification company. SGS is recognized as the global benchmark for quality and integrity. With more than 85,000 employees, they operate a network of more than 1,800 offices and laboratories around the world.

Testing Equipment

Chinese Graphite Automatic Balance Unit     Chinese Graphite Constant Temperature Furnace

Chinese Graphite Muffle Furnace     Chinese Graphite Laser Granulometer

Some of the equipment we use during our QA/QC process includes:

  • Automatic Balance Unit to measure the ash, volatiles, and moisture contents of our graphite, with an accuracy of 0.1mg
  • Constant Temperature Furnace to test moisture content
  • Muffle Furnace to test ash and volatiles contents
  • Laser Granulometer, or Particle Size Analyzer, for a thorough analysis of micronized graphite powder smaller than 74 µm
