Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, reference DM-HSD-GU119-IAQ, Version 4, issued 11 December 2024, does not simply set values and periods. It also settles who may produce the measurement, requiring that testing be carried out by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre. That single condition changes the status of a test report. A measurement produced outside it may be technically careful and internally consistent, and it still does not do the work the guideline expects of a result, because the guideline treats accreditation rather than asserted competence as the qualifying condition. This page sets out what the requirement is, what follows from it for the compliance route, and how it differs from a general claim of technical capability.
The guideline states that testing must be by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre. The condition attaches to the body carrying out the testing, not to an individual, a piece of equipment or a method description.
The requirement applies to testing carried out under the guideline, which covers both of its routes. A new building whose owner elects to apply the procedures under clause 9-8-3, in order to be awarded an indoor air quality certificate by Dubai Municipality, and an existing building for which clause 9-8-4 states that indoor air testing for the contaminants in Table 2 must be carried out, both depend on measurements produced under the accreditation condition.
Because the condition is expressed as a property of the testing body, it is capable of being checked before a survey is commissioned rather than argued about after results are produced. That is the practical purpose of writing a qualifying condition into the instrument.
A general competence claim is an assertion made by the party making it. Accreditation is a status conferred by an accreditation body against defined criteria and subject to that body's ongoing oversight. The guideline relies on the second rather than the first, and the difference is what allows a reviewing party to treat a report as evidence without reconstructing the technical judgement behind every reading.
It follows that phrases such as testing to international standards, laboratory-grade equipment or qualified technicians do not answer the guideline's condition. None of them establishes that the body carrying out the testing holds EIAC accreditation, which is the specific status the guideline names.
General laboratory accreditation to ISO 17025 as a subject in its own right is addressed by separate references and is not restated here; the point relevant to this compliance route is the named requirement for EIAC accreditation of the company or laboratory carrying out the testing.
An accredited body's report carries the measured concentrations together with the averaging basis on which each was produced. That basis matters because the instruments mix periods. Table 1 sets TVOC at 300 micrograms per cubic metre over 8 hours and formaldehyde at 0.01 ppm over 8 hours together with 0.08 ppm, equal to 0.1 mg/m3, over 30 minutes. Table 2 sets TVOC at 0.6 mg/m3 over 8 hours, carbon dioxide at 800 ppm over 8 hours, carbon monoxide at 9 ppm over 8 hours and ozone at 0.06 ppm over 8 hours.
The report also records the sampling arrangement, which the guideline constrains through Table 5 and clause 9-8-7: the number of points by floor area, probe placement 150 to 200 cm from walls and 100 to 200 cm from the floor, separation of 3.5 m from a lift or entrance in a corridor or lobby, 3 m from doors, and the 8-hour basis or its defined surrogate of four half-hour measurements evenly distributed over business hours.
The report does not determine scope. Whether the building is new or existing for the purposes of clauses 9-8-3 and 9-8-4, and whether it falls within the exclusion of premises exclusively dedicated to industrial and medical sectors, for example hospitals and factories, are questions settled before testing rather than by it.
The report also does not award anything. Clause 9-8-3 states that buildings which optionally apply the procedures will be awarded an indoor air quality certificate by Dubai Municipality, so the award sits with the Municipality. No party other than the authority issues it, and no validity period or retest interval is published for it.
The EIAC condition is written into the Dubai Municipality guideline. Al Sa'fat, the Dubai Green Building System, 2nd edition January 2023, reaches indoor air through its own provisions, requiring listed categories of existing building to apply testing under clause 401.07 with formaldehyde below 0.08 ppm as an 8-hour time-weighted average, TVOC below 300 micrograms per cubic metre as an 8-hour time-weighted average, carbon dioxide below 800 ppm, carbon monoxide below 9 ppm, ozone below 0.06 ppm and respirable dust below 150 micrograms per cubic metre, each as an 8-hour time-weighted average, and bacteria and fungi each below 500 CFU per cubic metre as per-sample counts that are not time-weighted.
The same number appears under both instruments on different bases. Dubai Municipality's eight-hour formaldehyde value is 0.01 ppm, and its 0.08 ppm figure is a thirty-minute short-term value. Al Sa'fat separately and correctly applies 0.08 ppm as an eight-hour time-weighted average. It is therefore incorrect to attribute 0.08 ppm over eight hours to Dubai Municipality.
Al Sa'fat also uses conferred status elsewhere in its structure: clauses 404.01 and 404.02 require VOC content limits set by Dubai Municipality and certified by Dubai Central Laboratory, landing on standard DMS 0020:2016. Those are grams per litre limits on product composition rather than airborne concentrations, so no averaging period applies to them, and the certifying body named there is not a substitute for the EIAC condition attached to air testing.
The Abu Dhabi route does not turn on an equivalent named accreditation for indoor air testing. The competent authority is the Abu Dhabi Public Health Centre and the framework is ADOSH-SF, whose Codes of Practice are mandatory to all entities regardless of risk classification, with indoor-environment and ventilation duties sitting inside Code of Practice 8.0 General Workplace Amenities, Version 4.0 of 15 July 2024, at section 3.7 on HVAC. There is no Abu Dhabi Code of Practice dedicated to indoor air quality.
Where Abu Dhabi does name a qualified party, it does so for a different function: Pearl Qualified Professionals prepare and submit Estidama compliance applications, with the Department of Municipalities and Transport governing the system's policies and Abu Dhabi City Municipality's Sustainable Buildings Section implementing it during the design and construction phases.
The comparison underlines what the EIAC requirement is for. It is a condition on the production of measurements in Dubai, not a general licence, and it does not travel to instruments that do not name it.
Testing must be by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre.
The condition covers testing under the voluntary clause 9-8-3 route and the clause 9-8-4 requirement for existing buildings.
Accreditation is conferred and overseen by an accreditation body rather than claimed by the testing party.
The indoor air quality certificate is awarded by Dubai Municipality under clause 9-8-3, not by the testing body.
Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, reference DM-HSD-GU119-IAQ, Version 4, issued 11 December 2024, require that testing be carried out by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre. Clause 9-8-3 covers new buildings that optionally apply the procedures and leads to a certificate awarded by Dubai Municipality; clause 9-8-4 states that testing must be carried out for existing buildings.
This is an independent information resource. It is not accredited, does not carry out testing and does not act for or on behalf of EIAC or Dubai Municipality.
Under Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, DM-HSD-GU119-IAQ Version 4 of 11 December 2024, testing must be by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre. The condition attaches to the testing body itself, so it can be checked before a survey is commissioned rather than debated after results exist.
The guideline names accreditation by EIAC rather than competence in general terms. A claim of qualified technicians, laboratory-grade equipment or testing to international standards does not establish the named status, and a result produced outside the condition does not support a compliance position under the guideline however carefully it was produced.
The testing body produces the measurement record and reports each concentration on its stated averaging basis. Scope questions, such as whether a building is new or existing for clauses 9-8-3 and 9-8-4 or whether it falls inside the exclusion of premises exclusively dedicated to industrial and medical sectors, are settled separately, and the indoor air quality certificate is awarded by Dubai Municipality under clause 9-8-3.
General laboratory accreditation to ISO 17025 is a broader subject addressed by separate references. What matters for this compliance route is the specific requirement written into the Dubai Municipality guideline that the company or laboratory carrying out the testing holds EIAC accreditation.
