公差制度是工業標準中的最重要標準之一。它的健全與否,對機械的設計和製造有着密切關係。我國工業過去由於對各帝國主義工業的依附性,全国各厂採用的公差制度很不一致。前經濟部全國度量衡局虽曾建議以國際公差制度為我國公差標準;但個别工厂有的尚採用德制,有的尚採用英美制,有的甚或「随機應變」,尚無一定公差制度之可言。這种在技術上的無政府狀態,顯然是極不合理的。
The tolerance system is one of the most important standards in industrial standards. Whether it is sound or not, it has a close relationship with the design and manufacture of machinery. In the past, due to the dependence on the imperialism industry, our country’s industry has adopted inconsistent tolerance systems across the country. Although the National Bureau of Measure and Economic Affairs of the former Ministry of Economics had proposed to use the international tolerance system as our country’s tolerance standard, some individual factories still use the German system, some still use the British and American system, and some even use “accidental changes”, and there is no certain tolerance system. It can be said. This kind of technological anarchy is obviously extremely unreasonable.
