工业管道用D系列蝶阀产品失效率数据

评估产品的失效率，判定安全等级，帮助企业改进产品；同时也向客户反馈产品的可靠性数据，增强客户订购我们产品的信心；降低阀门故障率，提升阀门使用寿命；收集产品正常安全运行时间、产品出现故障时间、产品故障次数、失效原因；按照卡方分布的反函数CHIINV(0.05,2*出现的故障总数+2)/2/该系列产品总的运行时长单位h，计算最大的失效率、最小的失效率、平均失效率；根据失效率的值依据IEC61508:2010标准，判定产品安全性等级，失效率10^-7~9.99*10^-7为SIL3；10^-8~9.99*10^-8为SIL4（最安全）

This dataset is used to evaluate product failure rates and determine safety levels to help enterprises improve their products. Meanwhile, it provides customers with product reliability data to enhance their confidence in ordering our products. It aims to reduce valve failure rates and extend the service life of valves. The dataset collects data including the normal and safe operating duration of products, the time when product faults occur, the number of product failures, and failure causes. The maximum, minimum, and average failure rates are calculated using the inverse chi-squared distribution function: CHIINV(0.05, 2 * total number of failures + 2) / (2 * total operating duration of this product series, unit: h). Based on the failure rate values and in accordance with the IEC 61508:2010 standard, the product safety level is classified: the range 10^-7 to 9.99×10^-7 corresponds to SIL3, while the range 10^-8 to 9.99×10^-8 corresponds to SIL4, which is the safest.
