Stainless steel weights
1. E1 grade, E2 grade, F1 grade weights
E1, E2, and F1 weights ranging from 1mg to 500kg should be of solid overall structure, made of a single piece of material without adjustment cavity.
Weights greater than 50kg
E2 and F1 weights greater than 50kg can have an adjustment cavity. The volume of the E2 weight adjustment chamber should not exceed 1/1000 of the total volume of the weight. F1 weights must not exceed 1/20. The adjustment cavity should be sealed, waterproof and gas-proof. Bolts with ribs, knobs or similar parts can close the adjustment cavity. The material should be the same as that of the weight, and its surface condition should meet the requirements of E2 and F1 weights.
After adjustment, the overall volume of the adjustment cavity is about 1/2 and should be empty.
2. F2 grade weight
F2 weights from 1g to 50kg
F2 grade weights from 1g to 50kg can have an adjustment cavity, and its volume should not exceed 1/4 of the total volume of the weight. The adjustment cavity should be sealed by lifting buttons or other methods.
After adjustment, about 1/2 of the total volume of the adjustment chamber should be empty.
F2 grade weights greater than 50kg
F2 grade weights larger than 50kg can be made of multiple materials and need to be sealed with waterproof or dust-proof welding. The weight can be composed of a variety of materials, and its magnetic properties should meet the requirements of F2 class weights.
F2 weights larger than 50kg can have an adjustment cavity, and the volume of the adjustment cavity should not exceed 1/20 of the total volume. The adjustment cavity should be sealed, waterproof and gas-proof. Ribbed bolts, knobs or similar components can close the adjustment cavity.
After adjustment, about 1/2 of the total volume of the adjustment chamber should be empty.
