5、准与JB/T50043—94的主要差异是：——第2章“引用标准”作了较大修改；——由于“引用标准”的修改，有关的技术内容也作了相应的增减；——“安全卫生”一章增加了“一般应有符合安全设计的三级防护措施”的要求，其有关条文也作了适当的调整；——按有关规定进行了编辑性修改。本标准自实施之日起代替JB/T50043—94。本标准的附录A和附录B都是标准的附录。本标准由全国金属切削机床标准化技术委员会提出。本标准由全国金属切削机床标准化技术委员会铣床分会归口。本标准负责起草单位：北京第一机床厂。本标准于1986年首次发布，1994年第一次修订。

6、II中华人民共和国机械行业标准JB/T50043－1999升降台铣床产品质量分等代替JB/T50043—94（内部使用）1范围本标准规定了升降台铣床的产品质量等级要求。本标准适用于工作台台面宽度200~500mm的立式升降台铣床、卧式升降台铣床、万能升降台铣床。其他一般用途升降台铣床的相同部分应参照执行。2引用标准下列标准所包含的条文，通过在本标准中引用而构成为本标准的条文。本标准出版时，所示版本均为有效。所有标准都会被修订，使用本标准的各方应探讨使用下列标准最新版本的可能性。GB/T3837.1—1983机床工具7∶24圆锥联结主轴端
