For example if a measurement result is 5.51V, and the limit is 5.50V. Is such a reading outside the limit? Does a safety problem exist? The answer is not a simple yes or no. A number of considerations need to be made, for example how critical is this measurement for product safety? In other words is there a safety risk? To answer such a question we need to understand the effect of tolerances. This includes the tolerance of the measuring instrument used, and of the circuit being tested. First measurement errors are briefly reviewed, followed by a brief discussion of the statistical significance. Then statistical techniques and risk management are used to determine if the reading is out of tolerance and what is the likelihood of a safety issue. This may seem an “overkill”, but we consistently hear about consumer goods catching fire. One cell phone is banned by all airlines as the chances that it will catch fire is considered too high to put passengers' lives at risk. Safety engineering does not make adequate use of statistical analysis to understand and prevent unsafe conditions.","PeriodicalId":211888,"journal":{"name":"2017 IEEE Symposium on Product Compliance Engineering (ISPCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123305495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true when testing is performed outside of the controlled environment of a laboratory as it may be in field evaluation. The variations in these environmental conditions raise concerns as to the requirement for the compensation of results and their documentation based solely upon the severity of their influences. By researching the general effects of environmental factors, including ambient temperature, atmospheric pressure, and humidity, on the various electrical properties of different electrical components and equipment, and applying such considerations to common compliance testing methods, the requirement for the technical documentation of these factors will be determined. The data analyzed suggested that each environmental factor exhibits similar effects to varying degrees when applied to the common compliance testing methods consisting of the dielectric strength test, leakage current test, ratings test, and temperature test. Ultimately, due to the variations in their significance when applied to common compliance testing methods, the consensus for evaluators of equipment to document environmental conditions in addition to compensating results is deemed necessary only while operating in environments to which specific conditions are severe enough to distort results.","PeriodicalId":211888,"journal":{"name":"2017 IEEE Symposium on Product Compliance Engineering (ISPCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128954710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The market access depends on the components. In this paper, the components of the biggest market in Africa are discussed. The three components that facilitate the market access of the Information and Communication Equipment are: the Standards Organization of Nigeria Conformity Assessment Program (SONCAP), the Nigerian Communications Commission (NCC) Type Approval and the Nigeria Customs Service Import Procedures. At the border, the NCS ensures that the Standards Organization of Nigeria (SON) and the NCC Rules are complied with before ICE can be imported into Nigeria. However, the NCC Regulation is based on the European Norms (EN) and deviates sometimes from the European Standards because of the peculiarity of the Nigerian environment. One of such is the Guideline for the Deployment of Broadband Service on 5.2GHz to 5.9GHz band. The paper elaborate the standards, the type approval process, the inherent risks and mitigation in the type approval procedure. The Radio and Telecommunication Terminal Equipment Directive applications as it relates to the NCC type approval are discussed vis-a-vis the NCC Type Approval Regulation, Guideline and other Nigerian Standards in equipment type approval.","PeriodicalId":211888,"journal":{"name":"2017 IEEE Symposium on Product Compliance Engineering (ISPCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114451549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
