National standard for error range of weighbridge

The measurement error range of the national standard is also divided according to different weighing and weight conditions, so the error cannot be generalized. According to national standards, the error less than 1 kg must be zero, and the error of 50 kg must be within 50 grams. If the weight exceeds150kg, the allowable error is100g. Therefore, whether a good scale is qualified can be determined according to such a standard.
