What is the accuracy requirement for a scale or cell when the load is 1,500 kg?

For a scale/cell load below 2,000 kg, an accuracy of ±1% is required. Therefore, for a load of 1,500 kg, the accuracy must be below ±1%.

What is the accuracy requirement for a scale or cell when the load is 10,000 kg?

For a scale/cell load from 2,000 kg to 20,000 kg, an accuracy of ±20 kg is required. Therefore, for a load of 10,000 kg, the accuracy must be below ±20 kg.

What is the accuracy requirement for a scale or cell when the load is 25,000 kg?

For a scale/cell load above 20,000 kg, an accuracy of ±0.1% is required. Therefore, for a load of 25,000 kg, the accuracy must be below ±0.1%.

Q: When can a new VCA that was weighed at the factory be operated without reweighing?

A new VCA that has been weighed at the factory may be operated without reweighing if the mass and balance records have been adjusted for alterations or modifications to the VCA.

Q: Under what condition must a VCA transferred between two EU operators be weighed prior to use by the receiving operator?

A VCA transferred from one EU operator to another EU operator does not have to be weighed prior to use by the receiving operator unless more than 4 years have elapsed since the VCA was last weighed.

Q: What specific precaution must be taken regarding the environment when weighing a VCA?

Ensuring that weighing is accomplished in an enclosed building.

ED Decision 2025/010/R

WEIGHING OF A VCA

(a) New VCA that have been weighed at the factory may be operated without reweighing if the mass and balance records have been adjusted for alterations or modifications to the VCA. VCA transferred from one EU operator to another EU operator do not have to be weighed prior to use by the receiving operator unless more than 4 years have elapsed since the VCA was last weighed.

(b) The mass and CG position of a VCA should be revised whenever the cumulative changes to the dry operating mass or CG exceed ± 0.5 % of the maximum landing mass or CG envelope respectively. This may be done by weighing the VCA or by calculation.

(1) checking for completeness of the VCA and equipment;

(2) determining that fluids are properly accounted for;

(3) ensuring that the VCA is clean; and

(4) ensuring that weighing is accomplished in an enclosed building.

(d) Any equipment used for weighing should be properly calibrated, zeroed, and used in accordance with the manufacturer’s instructions. Each scale should be calibrated either by the manufacturer, by a civil department of weights and measures or by an appropriately authorised organisation within 2 years or within a time period defined by the manufacturer of the weighing equipment, whichever is less. The equipment should enable the mass of the VCA to be established accurately. A single accuracy criterion for weighing equipment cannot be given. However, the weighing accuracy is considered satisfactory if the accuracy criteria in Table 1 are met by the individual scales/cells of the weighing equipment used.

Table 1: Accuracy criteria for weighing equipment

For a scale/cell load	An accuracy of below
2 000 kg	±1 %
from 2 000 kg to 20 000 kg	±20 kg
above 20 000 kg	±0.1 %
