Quality control / Certificates

Quality control

Our quality management system is certified according to DIN EN ISO 9001:2015. Main focus of the quality control is the process-controlling during the manufacturing process followed by a final check acc. to DIN ISO 3951 (sampling inspection). The used test equipment complies with the national standards and is checked regularly. Basis of all quality criteria are the respective national and international standards.

Volumetric instruments are manufactured in the standardized accuracy classes B, A/AS and A/AS-conformity. The conformity declaration certifies the compliance of the volumetric instrument with the relevant national regulations and standards acc. to the new Metrology and Verification, dated 01.01.2015.
Official calibrations are now referred to as "conformity assesments".




Individual certificate

An individual certificate can be issued for volumetric instruments of the accuracy classes A/AS-conformity and shows the exact determined volume. On each product an individual number is applied, which relates to the number on the certificate. For ordering add ’EC’ behind the product code. (example: 61 319 647EC)

Batch certificate

For all volumetric instruments of the accuracy classes A/AS and A/AS-conformity, order-related batch certificates are available. The batch No. on the product consists of batch No. and year of production (e.g. 06 12). For ordering add ’C’ behind the product code. (example: 61 321 025C)
