Service Background
Why do we need to conduct this testing and measurement guarantee as the foundation of technology? It is the main technical method to ensure the safety and reliability of aviation equipment. In order to meet the mission and task requirements under the new situation, aviation equipment has been significantly updated in both types and technologies. Metrology support must keep pace with the times, improve hardware construction, transform support systems, strengthen information integration and other metrology work.
Our Advantages
The service network covers the whole country. GRGTEST has established more than 30 metrology and testing bases in major economic circles across the country, set up more than 60 subsidiary companies, and formed a nationwide technical service and business marketing system, which can provide customers with close range and localized convenient services, and actively expand overseas layout.
The measurement capability covers comprehensively. Covering ten major fields of metrology, it is a national leader in radio, electromagnetic, and time-frequency fields. The headquarters has been recognized for over 1700 CNAS metrology projects and has established more than 120 highest metrology standards for enterprises.
The instruments and equipment are equipped with advanced technology. We have over 20000 sets of advanced precision standard devices and instruments both domestically and internationally, which can achieve simultaneous operation of multiple tasks and ensure timely inspection.
The service team is professional and efficient. A service team of over 1500 people is composed of first-class registered metrologists, CNAS laboratory assessors, members of the National Metrology Technical Committee, and senior metrological technical experts as the core backbone.
Prospective layout of scientific research and innovation. Led/participated in the revision of more than 50 national, industry, and group standards/specifications in the field of metrology, and participated in the co construction of the Guangdong Hong Kong Macao Greater Bay Area Quantum Precision Measurement Joint Laboratory.
Rich technical experience and accumulation: Over one million metrological calibration certificates are issued annually, establishing the metrological calibration capability for general and specialized instruments and equipment in the aviation field. We can provide metrological calibration services for aviation specific equipment such as eddy current flaw detectors and aircraft engine testers. The certificates can meet the requirements of authoritative review agencies at home and abroad such as CAAC, FAA, EASA, NADCAP, BOEING, AIRBUS, etc., providing high-quality instrument and equipment metrological calibration services for various aircraft maintenance companies, component manufacturers, aircraft manufacturers, aviation inspection agencies, etc.
Frequently Asked Questions
Q: What are verification, calibration, and testing? What's the difference?
A：Verification: Conduct according to the verification regulations, and provide a conclusion on whether it is qualified or not based on the verification regulations.
Calibration: It only provides recorded data, and whether it is qualified or not is judged by the person submitting it for inspection.
Testing: mainly refers to the type evaluation of new measuring instruments and imported measuring instruments, as well as the inspection of the net content of quantitatively packaged goods.
Verification is mandatory and a top-down process of value transmission; The school guidelines are voluntary by users and are a bottom-up traceability process.
Q: What is CNAS accreditation?
A: CNAS certification is the English abbreviation for "China National Accreditation Service for Conformity Assessment Certification". It was formed by the merger and reorganization of the original Chinese certification bodies, the China National Accreditation Service for Conformity Assessment (CNAB) and the China National Accreditation Service for Laboratories (CNAL). It is a national accreditation body approved and authorized by the China National Accreditation Service for Conformity Assessment (CNCA), responsible for the accreditation work of certification bodies, laboratories, inspection agencies and other related institutions.
