Brazil Homologation for Explosive Atmospheres


Explosive Atmospheres
An Explosive Atmosphere is an environment which contains gas, vapour, dust or fibers with oxygen, in such proportion that a spark from electric circuit or heating from a device may cause an explosion. Electrical equipment installed in these environments must be eliminated or isolated the source of ignition. In order to classify an industrial plant, it is necessary to determine the type of flammable substance present in the environment, its characteristics, the probability of such substance being released into the surrounding area and the environmental conditions. Also, it is necessary to verify which groups of flammable gases and vapors or combustible dusts and fibers may be present in an industrial plant. Besides, the maximum surface temperature of electrical equipment must always remain below the ignition temperature of the explosive mixture. Source of ignition and related electrical equipments need to comply with the Brazilian INMETRO Ordinance no. 115: 2022 and pass mandatory INMETRO certification in order to legally enter the Brazilian market.

INMETRO (National Institute of Metrology, Standardization and Industrial Quality) is a government department directly under the Ministry of Development, Industry and Foreign Trade of Brazil. With the enactment of new ordinances and implementation laws, more and more products are included into INMETRO mandatory certification scheme.

Our INMETRO certification service scope covers LED Light Sources, Road Lamps, Automotive Parts, Motorcycle Parts, Bicycle Parts, Dangerous Goods Transportation, Child Seats, Photovoltaic Products, Pressure Vessels, Household Appliances, Children's Toys and Supplies, Building Structure, Personal Protective Equipments, Explosive Atmosphere, Medical Equipments etc., a total of more than 700 products in 155 categories.

ATIC has been authorized by major Brazilian local certification bodies (OCPs) to perform INMETRO certification activities such as factory audits, sampling, and product testing in China and Asia Region. We serve more than 400 Chinese or Asian manufactures each year.
General Steps
Factory Audit and Sampling
After the certification started by Brazilian importer or ATIC legal representative, ATIC auditor will make an audit and sampling plan and make an appointment with manufacture for the onsite audit. After the appointment conformed ATIC auditors will perform the onsite factory audit and sampling. Generally the audit will take 1 day, the samples will be sealed and sent to designated testing labs.
Sample Testing
Generally testing samples shall be sent to the designated 3rd party labs, yet in some circumstance manufactures testing facility can be used. In this case, the lab assessment shall be done by ATIC auditor and all the testing shall be witnessed by ATIC auditors. Testing reports shall be submitted to ATIC auditors and OCP inspectors for review.
Legal Representative Audit
Importer or Legal Representative in Brazil will also be audited by OCP auditors, generally this audit will be focused on customer compliant procedure, warehouse management procedure etc. Such audit normally takes 1 day.
Approval and Maintenance
All reports and technical documentation shall be reviewed by ATIC and Brazilian OCP. INMETRO certificate will be issued and submitted to INMETRO by Legal Representative for registration. Registration number will be issued and shall be labeled on both product and package. Generally, maintenance shall be done each 6 months, 12 months or 18 months according to different ordinances.

Zone 0: An atmosphere where, under normal operation, a mixture of air and flammable substances in the form of gas, vapors or mist is present frequently, continuously or for long periods
Zone 1: An atmosphere where, under normal operation, a mixture of air and flammable substances in the form of gas, vapors or mist is likely to occur in normal operation occasionally
Zone 2: An atmosphere where, under normal operation, a mixture of air and flammable substances in the form of gas, vapors or mist is not likely to occur in normal operation but, if it does occur , will persist for only a short period
Combustible Dusts and Fibers
Zone 20: An atmosphere where, under normal operation, a cloud of combustible dust in the air is present frequently, continuously or for long periods
Zone 21: An atmosphere where, under normal operation, a cloud of combustible dust in the air is likely to occur in normal operation occasionally
