Center Certification & Testing International
basic introduction
Our services mainly involve the mechanical properties of ferrous metals, non-ferrous metals, mechanical equipment and parts. Tests and tests involving chemical composition analysis, metallographic analysis, hardness, corrosion performance, coating performance, microscopic analysis, fastener performance, pipe process performance, welding process evaluation and skill evaluation.
ZRLK provides a series of tests to identify and inspect the material performance, process performance and safety performance of metal materials products.
For products
Metal raw materials such as plates, bars, profiles, forgings, castings and all metal parts and related.

Standards involved
Our advantage
1. With a professional qualification and experienced expert technical team, we can provide you with professional consultation and services.
2. Have advanced laboratory equipment to ensure the accuracy and reliability of test data.
3. As a third-party testing and certification organization trusted by customers worldwide, we are your certificate of quality.
BSCI certification is an abbreviation of BusinessSocialComplianceInitiative, and Chinese is called business social standard certification. BSCI is an organization that advocates the business community to abide by social responsibility. At the same time, it is a non-profit organization.
CMA, the name is \"China Metrology Accreditation\", the abbreviation of \"China Metrology Accreditation\" in English. According to the provisions of Article 22 of the Metrology Law of the People’s Republic of China: “The product quality inspection agency that provides notarized data to the society must be evaluated by the metrological administrative department of the people’s government at or above the provincial level for the capability and reliability of metrological verification and testing. Qualified.\"
Laboratory accreditation is a third-party certification that CNAS has the ability to perform specific testing and calibration work for testing and calibration laboratories.
