This standard JB/T 54877-1999 specifies quality grading requirements for carbide reamers, including AQL and RQL values, nonconformity classification, and life tests. It applies to reamers produced according to GB/T 4251~4253. Products are classified into qualified, first-class, and premium grades, with strict AQL and RQL values for each grade. Nonconformities are divided into B class (three groups) and C class, covering blade cracks, surface roughness, dimensional deviations, etc. Life tests specify conditions such as machine tools, test blanks, and cutting parameters, with requirements for average life and coefficient of variation.
本标准JB/T 54877-1999规定了硬质合金铰刀的质量分等要求，包括AQL和RQL值、不合格分类及寿命试验。适用于按GB/T 4251~4253生产的铰刀。标准将产品分为合格品、一等品和优等品，并针对不同等级设定了严格的AQL和RQL值。不合格项目分为B类（三组）和C类，涵盖刀片裂纹、表面粗糙度、尺寸超差等。寿命试验规定了机床、试坯、切削规范等条件，并给出了平均寿命和变异系数要求。
