过滤器套件老化测试检验数据

本数据来源于过滤器套件老化测试前后检验数据，根据老化测试前后的数据对比，可以确认产品是否合格，为质量和技术管理部门对产品质量的把控、生产设备和工艺的改进提供依据。1.产品测试包括多个检验项目，每个检验项目包括多个性能指标，对每个性能指标在老化测试前后进行多次检验，根据前后检验数据的变化幅度，判断性能指标是否合格，在性能指标是否合格的基础上，判断检验项目是否合格，在检验项目是否合格的基础上，判断产品是否合格；2.性能指标是否合格的计算公式如下：定义某一性能指标老化测试前的三次检验数据为X1、X2、X3，则平均值为Xa，定义该性能指标老化测试后的三次检验数据为Y1、Y2、Y3，则平均值为Ya，定义该性能指标的老化测试前后的变化幅度阈值为&，该性能指标的实时变化幅值P=(Ya-Xa)/Xa，若P的绝对值不大于&，则说明该项性能指标合格，若某一检验项目的所有性能指标都合格，则该检验项目合格，若某一产品的所有检验项目都合格，则该产品合格；3.对变化幅度阈值&的说明：阈值&为常数值，对于产品的不同性能指标，其值的大小是不同的，阈值&的确定主要依据以下几点：（1）依据行业标准，行业标准规定某项参数老化测试前后的变化不得超过一定百分比；（2）依据历史数据和专家经验，设定合理的阈值&，但应符合行业标准；（3）依据客户需求和产品设计目标，设定高于行业标准的阈值&。This dataset is sourced from inspection data collected before and after the aging test of filter kits. Comparing the pre- and post-aging test data enables qualification assessment of the products, providing a reliable basis for quality and technical management departments to supervise product quality and optimize production equipment and processes. 1. Product testing covers multiple inspection items, and each inspection item includes several performance indicators. Multiple inspections are conducted for each performance indicator both before and after the aging test. The qualification of a single performance indicator is determined based on the variation range of its pre- and post-test inspection data. The qualification of an inspection item is then judged based on whether all its constituent performance indicators are qualified, and the final qualification of the product is determined based on whether all its inspection items are qualified. 2. The formula for judging the qualification of a performance indicator is as follows: Let three pre-aging test inspection datasets of a given performance indicator be X1, X2, X3, with their average value denoted as Xa; let three post-aging test inspection datasets of the same performance indicator be Y1, Y2, Y3, with their average value denoted as Ya; let the variation range threshold for this performance indicator before and after the aging test be &. The real-time variation amplitude P of the performance indicator is calculated as P=(Ya - Xa)/Xa. If the absolute value of P is less than or equal to &, the performance indicator is deemed qualified. An inspection item is considered qualified only if all its performance indicators pass the assessment, and a product is qualified only if all its inspection items meet the qualification criteria. 3. Explanation of the variation range threshold &: The threshold & is a constant value, and its value varies across different performance indicators of the product. The threshold & is determined primarily based on the following aspects: (1) Industry standards: Industry standards stipulate that the variation of a specific parameter before and after the aging test shall not exceed a certain percentage; (2) Historical data and expert experience: A reasonable threshold & can be set, provided that it complies with relevant industry standards; (3) Customer requirements and product design goals: A threshold & higher than the industry standard can be set based on customer needs and product design objectives.
