自粘式桡动脉压迫止血器老化测试检验数据

本数据来源于自粘式桡动脉压迫止血器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 derived from the inspection data of self-adhesive radial artery compression hemostats collected before and after aging tests. By comparing the pre-test and post-test data of the aging test, the qualification of the product can be verified, providing a reliable basis for quality and technical management departments to oversee product quality, and optimize production equipment and processes.
1. The product test encompasses multiple inspection items, with each inspection item containing several performance indicators. Multiple inspections are performed for each performance indicator both before and after the aging test. The qualification of the performance indicator is determined based on the magnitude of change in its pre- and post-test data. Subsequently, the qualification of the entire inspection item is judged based on the qualification status of its performance indicators, and finally, the qualification of the product is determined based on the inspection items.
2. The formula for judging the qualification of a performance indicator is specified as follows: Let the three sets of inspection data for a given performance indicator before the aging test be X1, X2, X3, with their pre-test average denoted as Xa. Let the three sets of inspection data for the same performance indicator after the aging test be Y1, Y2, Y3, with their post-test average denoted as Ya. Define the change range threshold for the performance indicator before and after the aging test as &. The real-time change 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 considered qualified. If all performance indicators under an inspection item are qualified, the inspection item is deemed qualified; if all inspection items of a product are qualified, the product itself is qualified.
3. Explanation of the change range threshold &: The threshold & is a constant value, and its value differs across various performance indicators of the product. The determination of the threshold & mainly follows the following principles:
(1) Compliance with industry standards, which stipulate that the change of a specific parameter before and after the aging test must not exceed a certain percentage;
(2) Setting a reasonable threshold & based on historical data and expert experience, while ensuring compliance with industry standards;
(3) Setting a threshold & higher than the industry standard based on customer requirements and product design objectives.
