The purpose of this Standard is to establish uniform and specific practices for calculating and rounding the numeric values used for inch and metric screw thread design data dimensions only. No attempt is made to establish a policy of rounding actual thread characteristics measured by the manufacturer or user of thread gages. Covered is the Standard Rounding Policy regarding the last figure or decimal place to be retained by a numeric value and the number of decimal places to be retained by values used in intermediate calculations of thread design data dimensions. Values calculated to this Standard for inch and metric screw thread design data dimensions may vary slightly from values shown in existing issues of ASME B1 screw thread standards and are to take precedence in all new or future revisions of ASME B1 standards as applicable except as noted in para. 1.2. of this Standard.

在剩下有差异的地方,本文重点选取包容原则和独立原则、偏置公差、复合公差和可逆要求等规则一一作对比。包容原则与独立原则独立原则和包容原则描述的是尺寸公差和形状公差之间的关系。对于包容原则(Envelop Principle),ASME Y14.5的规则1#和ISO 14405-1都有类似的解释,简单概括为“尺寸公差不仅约束尺寸,还约束形状公差”。...
