1.A2.2 WEIGHT

  1. Check if the weight is marked on the load. If it is, verify that it represents the weight of all parts of the load (e.g., a machine tool might not include the drive motor).

  2. Check the weight stated on any documentation.

  3. Look at a drawing of the load. If the weight is marked, check as in (1) above to ensure it includes all parts of the load.

  4. If the load is still on a trailer or truck, weigh it on a weighbridge.

  5. Estimate the weight of the load using tables of weights. These can be found in standards or suppliers literature.

The Table 1 gives the weight per unit volume for a range of materials:

Note

  1. In some cases, the above figures are average only and the actual weight may vary according to the particular composition/water content, etc.

  2. All figures have been rounded for convenience of use.

  3. When dealing with a hollow body, check whether it contains anything and whether any such contents are liable to move.
