Materials And Construction
- Cast iron
Customisation Options
- Nominal values to suit the scale under test
- Class M1 or M2
- Certificate on request

- Keep blocks dry and free of loose rust so the nominal value holds
Certification
- Classes M1 and M2
How It Compares
| Stainless steel cylindrical test weights | Stainless cylindrical sets cover E2 to M2 for balances and bench scales. Cast iron blocks cover the heavy values needed for floor scales and weighbridges. |
|---|---|
| Hiring test weights | Owning a set means a scale can be checked the day a dispute arises rather than the week a hire company is available. |

Official verification happens once a year. Everything in between is your own responsibility, and it takes a set of weights and twenty minutes.
Truck Scale Deck Sizing And Site Preparation
A weighbridge is bought once and lived with for a decade. These are the decisions that cannot be changed afterwards.
Cast Iron Block Test Weights Questions
Which class suits a weighbridge?
Normally M1, with M2 acceptable for coarser divisions. Send the capacity and division and we will confirm.
What sizes are available?
Values are made to suit the scale being verified. Tell us the capacity and the test plan and we will quote the values required.
Do you supply both cast iron and stainless weights?
Yes, cast iron blocks for industrial classes and stainless or chrome plated cylindrical weights for the fine classes.
