Purpose: The aim of this study is to examine various national standards and to suggest problems and improvements on KS (Korean Industrial Standards) in spectacle frames. Methods: We surveyed the latest published KS, ISO (International Organization for Standardization), JIS (Japanese Industrial Standards), DIN (Deutsches Institut fur Normung) and ANSI (American National Standards Institute) standards with relating spectacle frames. The titles that were considered in comparative study were terms and vocabulary, measuring system and terminology, marking, requirements and test methods, formers, screw threads, and others. Results: There were 9 different languages such as English (USA and UK), French, Russian, Japanese, Chinese, German, Italian and Spanish for the lists of equivalent terms and vocabulary in all standards except KS and ANSI, but gave an explanation for terms and vocabulary in only KS. Complementary terms and definitions were not existed in annex of KS and ANSI for measuring system and terminology, but they were included in annex of standards of the others. KS and ANSI standard for requirements and test methods differed from the ISO revision. Except JIS and ANSI, standards of formers were almost identical. KS standard of screw threads were similar to JIS. Standards of welded joints and nickel release did not exist in KS. Conclusions: All standards except ANSI tend to follow ISO, especially DIN is almost entirely identical to ISO. But KS is behind the times because it has been amended lately or established in accordance with older editions of ISO. Therefore, in order to assist quality control and safety for spectacle frames, KS standards shall be superseded by the specifications which is identical to ISO within a reasonable time.

저압배전반(Low-voltage switchgear and controlgear assemblies)에 관한 대표적인 국제규격으로는 IEC 60439 시리즈가 있어, 저압배전반의 형식시험(Type test)시 이 규격을 적용하여 시험하고 있으며, 한편으로 오랫동안 IEC 60439 시리즈의 규격 개정작업이 진행되어 첫 번째로 IEC 60439 시리즈 중 Par1(IEC 60439-1)이 2009년 1월 IEC 61439-1 (Low-voltage switchgear and controlgear assemblies. Part 1 : General rules) 및 IEC 61439-2 (Low-voltage switchgear and controlgear assemblies - Part 2 : Power switchgear and controlgear assemblies)로 대체 되었다. 본 고찰에서는 새로 제정된 61439-1 및 61439-2의 형식시험 항목 및 방법을 개략적으로 소개하여, 신 규격에 의한 배전반 형식시험에 도움을 주고자 한다.

Our study researched on unification of KS I ISO standard harmonized with ISO and Official Test Method enacted by Korean Ministry of Environment-drinking water and indoor air quality. We reviewed KS methods related to drinking water and indoor air quality for about 23,000 KS methods. KS methods related environmental field are classified as KS I, total 635 methods and 583 KS I methods were harmonized with ISO. For Environmental Standard methods for drinking water, 100 methods were reviewed according to 232 KS methods related to ISO/ TC 147 "Water Quality". Environmental Standard methods for indoor air quality were reviewed according to 95 KS standard methods related to ISO/TC 146 "Air Quality". By reviews and comparison tests for unifiable ES for drinking water and indoor air quality with KS methods harmonized with ISO, it was evaluated that for 100 ES methods for drinking water, 23 ES methods were unification complete, 29 ES methods were unification possible, 12 ES methods were unification impossible, no corresponding methods were found in KS I ISO for 36 ES methods and for 17 ES methods for indoor air quality,1 ES methods were unification complete, 3 ES methods were unification possible, 3 ES methods were impossible, no corresponding methods were found in KS I ISO for 10 ES methods.
