Class 8344 - Technical testing and analysis services of Central Product Classification (CPC) Version 2.1 includes these subclasses:

83441 Composition and purity testing and analysis services

This subclass includes:

  • testing and analysis of the chemical and biological properties of materials such as air, water, waste (municipal and industrial), fuels, metal, soil, minerals, food and chemicals
  • testing and analysis in related scientific fields such as microbiology, biochemistry, bacteriology, etc.

This subclass does not include:

83442 Testing and analysis services of physical properties

This subclass includes:

  • testing and analysis of physical properties such as strength, ductility, electrical conductivity or radioactivity of materials such as metals, plastics, textiles, woods, glass, concrete and other materials
  • tests for tension, hardness, impact resistance, fatigue resistance and high-temperature effects

83443 Testing and analysis services of integrated mechanical and electrical systems

This subclass includes:

  • testing and analysis of the mechanical and electrical characteristics of complete machinery, motors, automobiles, tools, appliances, communication equipment and other equipment incorporating mechanical and electrical components.

This subclass includes:

  • periodical technical inspection of automobiles, motorcycles, buses, lorries, trucks and other road transport vehicles

This subclass does not include:

83449 Other technical testing and analysis services

This subclass includes:

  • testing and analysis of a technical or scientific nature that does not alter the object being tested
  • radiographic, magnetic, and ultrasonic testing of machine parts and structures in order to identify defects. These tests are often conducted on site.
  • certification of ships, aircraft, dams, etc.
  • certification and authentication of works of art
  • radiological inspection of welds
  • all other technical testing and analysis services not elsewhere classified

This subclass does not include:
