JB/T 51215-1999

Manufacturers of feed processing units use this standard to grade and test their products. Quality inspection agencies and customers also rely on it to evaluate unit performance, reliability, and safety. This standard helps unify industry quality requirements, driving product improvement and market competition.

饲料加工机组的生产企业使用本标准来对其产品进行质量分等和检测。质检部门和用户也可依据本标准评估机组的性能、可靠性和安全性。该标准有助于统一行业质量要求，促进产品升级和市场竞争。

This standard specifies quality grading requirements for feed processing units (capacity below 2500 kg/h), including three grades: qualified, first-class, and premium. It covers performance indicators (e.g., productivity, energy consumption per ton, mixing uniformity), reliability indicators (availability, mean time to first failure), and safety/appearance requirements. Test methods address noise, dust, mixing uniformity, etc., while inspection rules use sampling and category-based judgment. The standard provides a unified basis for production, testing, and grading of feed processing units.

本标准规定了饲料加工机组（2500 kg/h以下）的质量分等要求，包括合格品、一等品和优等品三个等级。标准涵盖了性能指标（如生产率、吨料电耗、混合均匀度）、可靠性指标（有效度、首次故障前平均工作时间）以及安全、外观等要求。试验方法涉及噪声、粉尘、混合均匀度等检测，检验规则采用抽样和分类判定。该标准为饲料加工机组的生产、检测和分级提供了统一依据。
