Our services in the calibration laboratory for mass and solid body density

Based on our long-time experiences we offer accredited calibration services for the measuring quantity mass and solid body density according to ISO/IEC 17025 with DAkkS calibration certificate.

Our range of services includes the calibration of:

 

Weights and mass pieces of the class E1 according to OIML R-111

Realisation and dissemination of the SI-Unit mass by using mass scale

in the range of 1 mg to 50 kg of the class E1

e.g. single weights, set of weights

Through the use of high-quality, modern balances / comparators and semi-automatic comparators, as well as a climate system specially developed for the calibration process,   we meet the high conditions for the calibration of weights of the class E1.

 

Weights and mass pieces of the class E2 – M3 according to OIML R-111

in the range of 1 mg bis 50 kg of the classes  E2  F1  F2  M1  M2  M3

e.g. single weights, set of weights, disc weights

 

Weights according to OIML R-111

in the range of 100 kg bis 1000 kg of the classes  M1  M2  M3

 

Determination of the conventional mass and the mass for free nominal values

e.g. disc weights, dead weights for pressure balances up to 50 kg

 

Consideration and evaluation of magnetic properties of the classes E1 to F2

e.g. Susceptibility and Polarity of stainless steel weights

 

Determination of mass for Newton weights

e.g. disc weights up to 50 kg

 

Determination of solid body density and solid body volume

Application of the hydrostatic weighing principle (primary method)

in the range of 1 g to 20 kg

e.g. weights of the class E1, glass spheres, sinker

It is necessary to determine the density and the volume of the weights to meet the high accuracy requirements.

Our complete range of calibration services, including expanded measuring uncertainties, can be found in the Annex to accreditation certificate (D-K-15186-01-00).
