Note: 1. If the allowable deviation requirement is single positive or single negative, take 2 times of each value in the table as the standard. 2. When the customer has special requirements for the width and its allowable deviation, it shall be negotiated by the supplier and the buyer and indicated in the contract. | |||||||
