Description

Product information "E1 Miligrammweight"

Milligram weight made of stainless steel in wire form

Standard weights of the E1 class are suitable as adjusting, test and calibration weights for precision scales (class I) and for quality assurance according to DIN EN ISO 9001ff for scales with a graduation > 1 000 000.
These weights are used for calibration and verification of class E2 weights.
They are also suitable for high-precision weighing such as comparative measurements on mass comparators.
For a weight to be considered ISO 9000ff compliant test equipment, its accuracy must be verified. This is possible with a suitable DAkkS calibration certificate, which you can order from us.

 

Features E1 Milligram weight:

  • OIML class: E1
  • complies with Directive R111:2004 for weights
  • Nominal value: 1 mg - 500 mg
  • Material: stainless steel
  • Design: Wire form
  • A calibration certificate must always be issued for class E weights.

Note on the storage of weights of classes E and F

Please note that individual weights and weight sets must be stored in a way that protects them from wear and tear or damage caused by impacts or vibrations, according to DIN 8127-2007-11-OIML R 111-12004 (section 14.2.1). This ensures that the precision and accuracy of the weights are maintained over the long term.

Due to the very high precision of this weight class, we strongly recommend using a storage case.
Please order this separately when purchasing individual weights.
