Cabinet Resolution of 2023 Concerning the Technical Regulations for Air Quality Measurement 3

Article (2) Scope of Application This resolution shall apply to laboratories, environmental monitoring networks, and bodies working in measuring air pollutants specified in Cabinet Resolution No. (12) of 2006 for the Regulation Concerning Protection of Air from Pollution, and the atmospheric monitoring measurement instruments used in environmental monitoring networks, which include the following: 1. Ambient air quality measurements. 2. Indoor air quality measurements. 3. Air pollutants emitted from constant sources. 4. Air quality measurement instruments specified in table No. (1) attached to this resolution. 5. Sensors for measuring air quality and environmental pollutants specified in table No. (2) attached hereto; and 6. Sensors for measuring air quality and environmental pollutants for specific elements for non- industrial establishments and workplaces specified in table No. (3) attached hereto.

Article (3) Jurisdictions of the Ministry For the purposes of this resolution, the Ministry, in coordination with the competent authority and as case may be, shall implement the provisions hereof, and to this end it may undertake the following: 1. Ensure that measuring instruments used in environmental monitoring networks and air quality measurement laboratories are calibrated and that there are calibration certificates for such instruments in accordance with national and international requirements and prevent the use of instrument that do not conform to the specifications and technical regulations approved in the State. 2. Ensure that environmental monitoring networks are registered in the Ministry registration system in accordance with the procedures issued for this purpose.

Ensure that air quality measurement laboratories obtain international accreditation in accordance with the international standard (ISO/IEC 17025). 4. Take the necessary administrative measures to implement the requirements of this resolution, including contacting the competent authorities to cancel the licence for entities or laboratories that violate the requirements stipulated herein. 5. Determine competency testing programmes in collaboration with the relevant authorities to organise such programmes and supervise implementation thereof.

Article (4) Requirements for Laboratories/Environmental Monitoring Networks Laboratories and environmental monitoring networks shall adhere to the following: 1. Register at the Ministry in accordance with the procedures and requirements issued by the Ministry for this purpose. 2. Obtain accreditation according to the standard specification (ISO/IEC 17025) in accordance with the requirements of the National Accreditation System issued pursuant to Cabinet Resolution No. (22) of 2004 by laboratories working in the field of testing air quality. 3. Acknowledge that tests or calibrations specified herein shall not be submitted if they have not obtained accreditation within one year from the effective date of this resolution. 4. Participate in competence programmes determined by the Ministry on an annual basis. 5. Limits for accepting results for competence programmes shall be determined by the Ministry within the programme details. 6. If the errors in the measurement results of laboratories or environmental monitoring networks exceed the permissible limits as specified by this resolution, operations in this field shall continue until compliance is achieved or appropriate corrective action is taken.
