硫酸亚铁出厂检验检测数据集

1. 数据来源：采集硫酸亚铁出厂检验原始数据，涵盖主含量、水分、重金属（铅 / 砷）等核心质检指标，及检测设备参数、实验室温湿度、操作人员记录。2. 数据清洗规则：剔除缺失主含量、重金属指标的无效数据；过滤设备故障导致的极值（如主含量＞105% 或＜90%）； 统一单位（水分换算为质量分数 %）并校验逻辑一致性。 3. 数据加工规则：按国标设定阈值：主含量≥98.0%、水分≤1.0%、铅≤0.0005%、砷≤0.0002%；关联设备校准信息，生成 “合格 / 不合格” 分级标签，输出结构化分析数据集。1. Data Source: Raw factory inspection data of ferrous sulfate was collected, covering core quality inspection indicators including main content, moisture, heavy metals (lead/arsenic), as well as testing equipment parameters, laboratory temperature and humidity, and operator records. 2. Data Cleaning Rules: Invalid data with missing main content or heavy metal indicators are eliminated; Extreme values caused by equipment malfunctions (e.g., main content >105% or <90%) are filtered; Units are unified (moisture is converted to mass fraction %) and logical consistency is validated. 3. Data Processing Rules: Thresholds are set per national standards: main content ≥98.0%, moisture ≤1.0%, lead ≤0.0005%, arsenic ≤0.0002%; Associate with equipment calibration information to generate "qualified/unqualified" graded labels, and output a structured analytical dataset.
