Manufacturers of sound level meters and sound level calibrators must have a conformity assessment performed before placing their products on the market. Since January 2015, the certificate of conformity may be issued by private-sector companies.
As an accredited and recognized certification body (CB), we are happy to perform the conformity assessment of your sound level meters and sound level calibrators for you.
We are accredited according to DIN EN ISO/IEC 17065 by the German Accreditation Body DAkkS under the code D-ZE-15183-01 (in German) and recognized under the Measurement and Calibration Act (MessEG) by the Federal Ministry for Economic Affairs and Energy (BMWE) (formerly the Federal Ministry for Economic Affairs and Climate Action – BMWK) under the identification number DE 0002 (in German).

Expertise
Based on our accreditation under DIN EN ISO/IEC 17065 as a product certification body by DAkkS, as well as our subsequent recognition as a conformity assessment body (DE 0002) by the BMWi in August 2022, we are able to offer you conformity assessments in accordance with the Measurement and Calibration Act (MessEG) / the Measurement and Calibration Ordinance (MessEV), Annex 4, Module F.
The list of recognized conformity assessment bodies for nationally regulated measuring instruments, as required by Section 8(1) of the Measurement and Calibration Act, is published on the website of the Federal Ministry for Economic Affairs and Energy (BMWE).
With our calibration laboratory, accredited since 2011 (D-K-15183-01), we can draw on extensive expertise in the field of acoustics. In addition, we have been working closely for several years with various calibration authorities in the area of calibration and re-calibration of sound level meters and sound level calibrators.
Our services
We confirm compliance with the applicable type approval or type certification for:
- Sound level meters
- Sound level calibrators
Assessments are conducted in accordance with the Act on the Reform of Legal Metrology of July 25, 2013 (MessEG).
CB SPEKTRA performs exclusively 100% inspections in accordance with Annex 4, Module F, Section 4 of the MessEV. We do not offer conformity assessments using statistical methods in accordance with Section 5 (e.g., inspections of samples from a large batch).
If you are interested in a conformity assessment, a certification agreement is concluded between the client and CB SPEKTRA. This agreement is based on the price list and the Testing and Certification Regulations (PZO), which govern the conduct of the certification process.
Sound level meters and sound calibrators available on the market are subject to the following rules and regulations, on the basis of which the conformity assessment is conducted:
- Measurement and Calibration Act (MessEG) and Measurement and Calibration Ordinance (MessEV)
- the set of application rules as specified in the respective type approval / type examination certificate (harmonized standard, such as DIN EN 61672, or other technical specification)
The fundamental rules and procedures under which we operate as a certification body, as well as their administration, are non-discriminatory.
Applicants’ access is not restricted or prevented. All services are available to all applicants. They do not depend on the size of the client's company or on membership in an association or group and are not subject to the number of certifications already issued.
There are no unfair financial or other conditions. If anything, our requirements, evaluation, assessment, decision-making and monitoring are limited to matters specifically related to the scope of certification.
We process all requests in the order in which they are received. With a planned turnaround time of no more than 14 days after the order is placed and your measuring equipment is received, we are committed to completing the work quickly. We appreciate your understanding if delays do occur, for example, due to high demand.
