Scientific range of
weights and masses in classes E, F and M


OIML WEIGHTS FROM 1mg to 50kg
E0, E1 and E2 classes

These weights, except E0 class, are according to the international OIML R111 recommendation in terms of material (roughness, magnetism, …) and shape and marking.

Class E1 weights are intended to ensure traceability between national mass standards and weights of a lower accuracy class.

Class E2 weights are intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I. Class E2 weights or weight sets have to be accompanied by a calibration certificate.

 

OIML WEIGHTS FROM 1mg to 50kg
F1 and F2 classes

These weights are according to the international OIML R111.

Weights intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I and high accuracy class II. They can also be used as control weights and are usually accompanied by a calibration certificate.


OIML WEIGHTS FROM 1mg to 50kg
M1, M2 and M3 classes

These weights are according to the international OIML R111.

Weights intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of medium accuracy class III and ordinary accuracy class IIII. They can also be used as control weights and are usually accompanied by a calibration certificate.


MASSES FROM 100 kg to 2t
E, F and M classes

These masses are intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I, high accuracy class II and medium accuracy class III. They are usually accompanied by a calibration certificate.

All these masses can be handled with slings to be fixed at the rings.

M class weights with feet have been conceived to be stackable and can be handled with a forklift truck or pallet lift.

 

 

 

 

 

MADE-TO-MEASURE, FROM DESIGN TO PRODUCTION

ZWIEBEL is there to assist you in defining, studying and producing
your specific weights and masses.


Zwiebel's know-how:

  • All types of material: brass, aluminium, stainless steel, steel, cast iron, plastic etc.
  • All shapes and compositions: monobloc, with adjusting cavity, cylindrical, cubic etc.
  • All types of finish: highly polished, brushed, painted, surface-coated
  • All tolerances: either comply with OIML classes or specific tolerances
  • All types of identification: laser marking, diamond point engraving, paint identification
  • Accessories adapted to your needs (table, handling system, protective mechanism and packaging etc.)

 

 

 

Our laboratories are accredited by the COFRAC and benefit from an international recognition. The certification ISO 9001-2008 strengthens our commitment quality.

IDENTIFICATION
Identifying the weights and masses is vital for ensuring the traceability of calibrations carried out.


This is ideally carried out on the weights or, by default, on the case (unless there is a technical impossibility or a specific request that needs to be specified on order).Without identification, the COFRAC calibration certificate cannot be given.

Precision Weights and masses

DO YOU REQUIRE an industrial - or a science-based approach for your needs? Are you seeking quality, effectiveness and high performance?
Zwiebel will shape your requirements.

Good to KNOW

Our experience enables us to propose packaging in plastic, wood or metal for standard weights or masses and for
those that are non-standard in dimension.
