This standard JB/T 51192-1999 specifies the product quality grading requirements for agricultural screw oil presses, including performance indicators (such as residual oil rate in cake, oil extraction efficiency, power consumption per ton, noise, productivity, working time before first failure, etc.), test methods, and inspection rules. Products are classified into three grades: qualified, first-class, and premium. Specific indicator values are provided for different machine models (e.g., 200 type, 95 type) and oilseeds (peanut, rapeseed, soybean, cottonseed). Inspection follows a counting sampling plan, with nonconformities categorized into A, B, and C classes. This standard replaces the previous version and incorporates several revisions to the indicators.
本标准JB/T 51192-1999规定了农用螺旋榨油机产品的质量分等要求，包括性能指标（如干饼残油率、出油效率、吨料耗电、噪声、生产率、首次故障前工作时间等）、试验方法和检验规则。标准将产品分为合格品、一等品和优等品三个等级，并针对不同机型（如200型、95型等）和油料（花生、油菜籽、大豆、棉籽）给出了具体指标值。检验采用计数抽样方案，按A、B、C三类不合格项目进行判定。该标准替代了旧版标准，并在指标上进行了多项修订。
