Scope
This standard specifies the guiding principles and assessment methods for grading the quality of cutting tools, as well as the sampling acceptance methods for various standard tools produced in batches. This standard is applicable to the grading assessment of the quality level of cutting tool products produced in batches. This standard is a supplement and development to the current tool standards, serving as the basis for product quality assessment, grading and classification, as well as the basis for the competent authorities to assess enterprise quality, industry supervision and inspection, and enterprise quality spot checks. For the quality inspection of continuous batch products, the sampling plan specified in GB/T 2828-1987 'Sampling procedures and tables for lot-by-lot inspection by attributes (applicable to inspection of continuous batches)' applies to the batch inspection and acceptance of products before packaging and warehousing during the production process by the manufacturer. It also applies to the lot-by-lot inspection and acceptance by large-scale ordering users. For the periodic inspection of the stability of the production process, the sampling plan specified in GB/T 2829-1987 'Sampling procedures and tables for periodic inspection by attributes (applicable to inspection of stability of production process)' applies to the periodic inspection (by month, quarter, etc.) of product quality by the manufacturer's quality supervision department and the periodic inspection or irregular spot checks of factory product quality by competent authorities at all levels (or entrusted quality supervision agencies). The symbols and terms used in this standard, unless otherwise specified, are in accordance with the provisions of GB/T 2828 and GB/T 2829.
本标准规定了刀具质量分等的指导原则和评定方法及成批生产的各种标准刀具的抽样验收方法。本标准适用于成批生产的刀具产品质量水平的分等评定。本标准是现行刀具标准的补充和发展，是产品质量考核、分等定级的依据，也是主管部门考核企业质量、行业监督检查及企业质量抽查的依据。对连续批产品的质量检查，按GB/T 2828—1987《逐批检查计数抽样程序及抽样表（适用于连续批的检查）》规定的抽样方案，适用于制造厂在生产过程中产品包装入库前的批检查验收。也适用于大批订货用户的逐批检查验收。对产品生产过程稳定性周期检查，按GB/T 2829—1987《周期检查计数抽样程序及抽样表（适用于生产过程稳定性的检查）》规定的抽样方案，适用于制造厂质量监督部门对产品质量的周期检查（按月、季等）和各级主管部门（或委托的质量监督机构）对工厂产品质量的周期检查或不定期抽查。本标准采用的符号和术语，除另有说明外，均按GB/T 2828 和GB/T 2829 规定。

This standard specifies the principles, assessment methods, and sampling acceptance procedures for grading the quality of batch-produced cutting tools. It applies to manufacturers for quality grade evaluation and to competent authorities for supervision and inspection. The standard classifies nonconformities into three categories (A, B, C) and defines sampling plans based on AQL and RQL, along with life test requirements. Through lot-by-lot and periodic inspections, it ensures product quality stability and consistency.
本标准规定了成批生产刀具的质量分等原则、评定方法及抽样验收程序。它适用于制造厂对刀具产品进行质量等级评定，也用于主管部门的监督检查。标准将不合格分为A、B、C三类，并规定了基于AQL和RQL的抽样方案，以及寿命试验要求。通过逐批检查和周期检查，确保产品质量的稳定性和一致性。

对连续批产品的质量检查，按GB/T 2828—1987《逐批检查计数抽样程序及抽样表（适用于连续批的检查）》规定的抽样方案，适用于制造厂在生产过程中产品包装入库前的批检查验收。
对产品生产过程稳定性周期检查，按GB/T 2829—1987《周期检查计数抽样程序及抽样表（适用于生产过程稳定性的检查）》规定的抽样方案，适用于制造厂质量监督部门对产品质量的周期检查（按月、季等）和各级主管部门（或委托的质量监督机构）对工厂产品质量的周期检查或不定期抽查。
凡被检查的产品不符合标准和技术条件规定要求的地方，均称为不合格。
按逐批检查结果计算得出的各Pˆ 值，分别和产品各组不合格的AQL 指定值比较，符合哪一等级的即评为该等级品。

Any place where the inspected product does not meet the requirements of the standard and technical conditions is called a nonconformity.
The calculated Pˆ values based on the results of lot-by-lot inspection are compared with the specified AQL values for each group of nonconformities of the product, and the grade that matches is assessed as that grade product.
