ELECTROACUSTICS
One of our laboratory's great differentials is that it complies with all the strict CGCRE accreditation requirements, participating with satisfactory (reliable) results in proficiency tests - EP for an extensive range of electroacoustic calibrations demanded by the HSE market - Health Safety and Environment, the Inspection Sector of Environmental Agencies, Military Police, City Hall, etc.
Generally, in the field of electroacoustics, each service provided within the scope of CGCRE refers to a calibration method that is linked to an ABNT standard or an international standard recognized in Brazil. For each version of this "standard accredited by the laboratory", CGCRE considers a new method, so for the same type of equipment we can have as many different methods as there are versions of the aforementioned standard.
In accordance with the conventions of the International Electrotechnical Committee (IEC), electroacoustic equipment must be calibrated in accordance with the manufacturer's declared manufacturing standard. Our laboratory is accredited and prepared to calibrate electroacoustic equipment manufactured from the publication of the IEC651:1979 standard to the most up-to-date meters, regardless of the make or model on the market.
Every customer should be aware that in order to meet INMETRO requirements, their electroacoustic equipment, regardless of make or model, must have a microphone that is detachable from the rest of the electronics or body of the equipment, so that CGCRE-accredited laboratories can meet the standards of manufacture and periodic verification, known here as calibration, must inject electrical signals exactly where the microphone is connected, so if the microphone is not removed there is no possibility of carrying out the required tests.
In general terms, international electroacoustic standards are updated to impose necessary improvements on manufacturers, such as adapting to technological innovations in terms of new components launched by the semiconductor industry, the ability to support more powerful and robust software, as well as improving calibration tests, making them more comprehensive and rigorous, In essence, electroacoustic equipment should not necessarily meet the technical requirements of standards published after it was manufactured and, on the other hand, new equipment generally meets or exceeds the requirements of old standards. However, according to international agreements, accredited laboratories cannot calibrate electroacoustic equipment according to a standard not supplied by the manufacturer.
VIBRATIONS
One of our laboratory's great differentials is that it complies with all of CGCRE's strict accreditation requirements, participating with satisfactory (reliable) results in proficiency tests - EP for an extensive range of electromechanical calibrations that the industry market in general, HSE - Health Safety and Environment, the Inspection Sector of Environmental Agencies, etc. demand.
Generally, in the field of electroacoustics, each service provided within the scope of CGCRE refers to a calibration method that is linked to an ABNT standard or an international standard recognized in Brazil. For each version of this "standard accredited by the laboratory", CGCRE considers a new method, so for the same type of equipment we can have as many different methods as there are versions of the aforementioned standard.
Another point to note is that, as well as being accredited by CGCRE, the laboratory's high investment in top-quality, state-of-the-art equipment imported from countries such as Germany, Denmark and the USA provides our clients with a wide range of amplitude and frequency calibrations with the best traceability transfer accuracy.
In accordance with the international conventions of the International Organization for Standardization (ISO) committee, electromechanical equipment for measuring human body and machine vibration must be calibrated in accordance with the manufacturer's declared standard. Our laboratory is accredited and prepared to calibrate electromechanical equipment for measuring human body vibration manufactured from the publication of the ISO8041:1997 standard to the most up-to-date vibration meters and accelerometers, regardless of brand or model on the market.
It is only important to remember that for occupational purposes only vibrometers manufactured after 2005 may be used
Every customer should be aware that in order to meet INMETRO requirements, their electromechanical vibration measuring equipment, regardless of make or model, must have an accelerometer that can be detached from the rest of the electronics or the body of the equipment, because laboratories accredited to meet manufacturing standards and periodic verification, known here as calibration, must inject electrical signals exactly where the accelerometer is connected, so if the accelerometer is not removed there is no possibility of carrying out the required electrical tests, and it is limited to mechanical tests only.
In general terms, international electromechanical standards are updated to impose necessary improvements on manufacturers, such as adapting to technological innovations in terms of new components launched by the semiconductor industry, the ability to support more powerful and robust software, as well as improving calibration tests, making them more comprehensive and rigorous. Therefore, electromechanical equipment in its essence should not necessarily meet the technical requirements of standards published after its manufacture. On the other hand, new equipment generally meets or exceeds the requirements of older standards, but according to international agreements, accredited laboratories cannot calibrate electroacoustic equipment to a standard not supplied by the manufacturer.
