Welcome to
Global Accreditation System
About us

The Global Accreditation System (GAS) was established to assess the competence and impartiality of certification bodies, inspection bodies, laboratories, and other organizations performing conformity assessment activities.
The main objective of GAS is to ensure trust in the results of these organizations by conducting an objective, transparent, and professional accreditation process that complies with international principles.
The activities of GAS are aimed at improving the quality and reliability of conformity assessment services, fostering international cooperation, mutual recognition of accreditations, and ensuring open access to information about accredited bodies.
The organization operates based on independence, impartiality, transparency of processes, and equal treatment of all applicants.
Coordination and strategic management of GAS activities are carried out by the Coordination Council, which is responsible for:
- developing and updating accreditation policies, procedures, and methodologies;
- monitoring compliance with international standards and requirements (such as ISO/IEC 17011, ISO/IEC 17021, ISO/IEC 17025, etc.);
- organizing the training of experts and technical assessors;
- maintaining the quality management system of GAS itself;
- ensuring openness and access to information through the official Register of Accredited Bodies.
Accreditation criteria represent a set of requirements that a certification body, inspection body, or laboratory must meet in order to be accredited.
They include:
- Criteria related to the management system (structure, processes, independence, impartiality, confidentiality, and effectiveness of decision-making);
- Criteria related to personnel qualification (education, experience, competence, continuous development, and performance evaluation);
- Criteria related to the working environment, equipment, and assessment tools (technical infrastructure, calibration, control methods, and suitable conditions for testing or auditing);
- Criteria related to climate and environmental aspects of activity, which take into account the impact of climatic factors on measurement accuracy and stability, energy efficiency requirements, resource management, emission reduction, and adherence to sustainable development principles.
Accreditation is carried out in accordance with established rules. The issued accreditation certificates are entered into the Register (link to the register) indicating their status, validity period, and scope of accreditation.
