与大家共分IPI知识 有兴趣就了解一下，还是不错的，UL每年都要搞一個培訓, 那就是跟蹤服務檢驗(Follow-Up Service Inspection)的培訓, 而且收費很貴價格達１２００元／人， 看到这些人就烦。
UL驗廠分為日常不預約的跟蹤檢驗, 包括根據標簽量, 分期(如季)檢驗, ON CALL(有生產時預約)幾種. 還有一種是特殊型驗廠, 如跟進V/N, 首次生產檢驗(Initial prodoction Inspection, 又稱IPI). 當然, 如果你一而再地被檢驗員(又叫現場代表), 開出V/N, 而且問題又很嚴重, 那就成了另一種檢驗了, 叫加强检验计划 (Increased Inspection Program, IIP).......
几个概念先弄清楚:
报验服务 (On-Call Service)
当您申请的UL标志是非经常性的在工厂检验中出现，或仅使用在产品的短期制造过程中时，制造商便可考虑申请报验服务 (On-Call Service) ，以减少检验的次数。
首次生产检验 (IPI)
首次生产检验(IPI)主要是针对新制造商客户进行产品的生产检验，或是针对既有制造商生产的新领域产品进行认证，以确保所有制造商的产品制造流程皆符合跟踪检验计划的要求。
加强检验计划 (Increased Inspection Program, IIP)
加强检验计划(IIP)是一个协定，即当制造商无法生产符合UL标准及其跟踪检验计划标准的产品时，UL的工厂检验人员除了对其生产工厂进行正常性的检验之外，还会进行加强性的审核评估。


附件為UL細則的第一頁, 要學會看細則, 還真得先把這一頁看懂了.
1. Authorizaton Page:
俗稱授權頁, 一個UL檔案可能只有一個申請者(Applicant), 有时还有不同的列名者(Listee), 可以有很多個生產工廠(Manufacturer, 一般会列在Addendum to Autorization Page), 每增加一個生產工廠, 就會修改一次授權頁, 這是工廠是否有取得ul授權的象徵. 在這裡你也會找到該檔案授權類型是L還是R等. 如果每個Vol授權的工廠不一樣, 那每個Vol都會有一個授權頁.
有个概念, 什么是L类检验什么是R类检验?
L 及 R 类 (Type L & Type R) 的跟踪检验服务
在首次生产检验 (IPI) 之后，被授权的UL工厂检验人员将会定期前往生产工厂进行随机检验，此种检验称为L及R类 (Type L & Type R) 的跟踪检验服务。
è L类的跟踪检验服务 – 根据制造商在产品或系统上使用的UL认证标志的数量，进行工厂的跟踪检验服务。
è R类的跟踪检验服务 –每季定期对产品或系统进行工厂的跟踪检验服务。

1. UL跟踪检验频次
UL对工厂实施跟踪检验频次有明确的规定。

● R类服务

在正常情况下，对于大多数的R类工厂，检验员访问频次为每年四次，但并不排除一季度两次的可能性，除非有特殊指令，总数不得超过四次。如果检验时出现产品不符合UL要求而需要返工时，UL检验员会额外增加一次检验以确认出货时产品已经返工，且符合UL要求。

对于On-Call服务，则为至少每年一次。

还有不少产品，只有最少的检验次数，如标签，印刷材料等产品，只要求每年一次，最多不超过每年两次。

● L类服务

对于L类工厂，检验频次决定于UL标签的使用数量（通常和产品的产量成正比）和产品的复杂程度。UL规定了需要一次检验的产品的数量，同时也规定每一季度最大的检验次数。



● 特殊检验服务(SPI)

如果你违反了与UL所签署的《跟踪检验协议》，你就有可能受到UL的严厉处罚，包括对你工厂实施特殊检验。

-----------------------------------------------------------------------------------------
2. UL跟踪检验费用

UL的跟踪检验费用由两大部分组成，其一是年度服务费，其二是跟踪检验费用。在今年，其年度服务费为580美元，在每年的一月份，UL会将帐单寄到工厂，这对于R类和L类产品都相同；如果，跟踪检验细则中要求送样到美国进行测试，则UL还会向工厂收取测试费用；对于跟踪检验费用，R类和L类产品有着很大的区别：

● R类服务

R类服务，其跟踪检验费与检验次数有直接的关系。如果检验员在访问工厂时，工厂正在生产或库存有UL产品，则每次检验费用为280美元；反之，则为93.5美元；如果因产品返工而导致增加检验次数，则该次检验也按93.5美元计算。检验费用与产品的复杂程度与检验员在工厂所需的时间无直接关系。如果属于特殊检验，则一般情况下由检验在工厂所花的时间和当时检验的费率来决定，该费率在UL决定实施特殊检验时会通知工厂。帐单一般会在检验实施后的一个月内寄到。

● L类服务

对于L类服务，UL是通过标签来收取跟踪检验费用的。在工厂向UL申请购买标签时，标签的价格包含了两方面的费用：标签的成本和服务费（即UL的跟踪检验费用）。因此，UL现场代表在检验工厂时，UL不再向工厂收费，除非是大量的产品复验或是UL对工厂实施了特殊检验

很详细很具体

so good and detailed...

But one thing I still need to remind everybody about the IPI, pls kindly remember:

Don't sheep out the products with the UL mark unless the IPI is finished and can fulfill UL's requirements....

对于电线、插头多少数量检验一次？

很好的文章哦

跟踪检验费和厂检费是一个概念不，我们的账单每次都是666

详细阐述了UL验厂知识，收藏学习。

哇，很多哦，我仔细看看
