Certification of Sound Level Meter (Not calibration)

AI Thread Summary
The discussion focuses on finding certification services for Sound Level Meters to meet IEC 61672 standards, distinct from calibration. Richard Amster seeks recommendations for certification providers and receives a suggestion to contact Dekra Certification Inc. Another participant mentions having their meter certified at PCE Instruments. There is also a suggestion that purchasing a new meter might be more cost-effective than certifying an existing one, especially for lower-value equipment. The conversation highlights the importance of proper certification for sound measurement instruments.

Hi,

I would like to know if anyone knows where can I find people who do certification of Sound Level Meter (Not calibration).

I need to certify my Sound Level Meter to IEC 61672.

Please provide details if you know who can do it.

Thank you.
Best Regards,
Richard

Hi Bobbywhy,

Thank you for your reply, I wrote to them to see if they can provide such service.

Anyone else have any other contact please let me know.

Thank you in advance.

Best Regards,
Richard
 
Great! Thanks for letting us know.
 
You may wish to consider simply purchasing a new meter. I know this sounds odd, but I've found the calibration expense on lower value test equipment often exceeds the price of a new piece with certs.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
