螺纹钢的负公差率得到提高。
为了使配合零件之间具有过盈或强制配合，公差必须产生零或负允差。
To have an interference or force fit between mating parts, the tolerances must be such as to create a zero or negative allowance.
进口设备的实际重量应不少于附录IV中规定的95 %，或负5%的测量允许公差。
The actual weight of imported Equipment shall not be less than 95% of the total weight per Appendix iv, or a measuring tolerance of negative 5%.
