  • Purpose: The purpose of this study was to propose useful standards evaluation method using standards networks by analyzing the relationship between normative references citation information list. Methods: The collected data through the survey were analyzed using social network analysis. The measurement tools used for this study were divided into three dimensions such as certificate standard, normative reference and degree centrality. Results: The results of this study are as follows; regarding the influence of standard information, It is meaningful that the research using normative reference item among the bibliography information that the standard itself possesses. The analysis of social network analysis data of population standard, normative reference and the correlation analysis with sales, a variable representing actual utilization performance, suggested the importance of the standard and how to evaluate it. Conclusion: In prioritizing standard maintenance, more efficient management will be possible if centrality figures of standard network information are analyzed and used for standard maintenance.

  • The Energy Efficiency Standards and Labelling Act, as amended by the Rational Energy Utilization Act, provides energy efficiency standards and labellings for six equipment categories(viz, refrigerators, air-conditioners, fluorescent lamps and ballasts, incandescent lamps, cars) authorizes the Ministry of Trade. Industry and Energy (MOTIE) to prescribe amended or new energy efficiency standards and labelling standards. This study was initiated by the KIER(Korea Institute of Energy Research) in 1992. KIER's assessment of the appliance energy efficiency standards is designed to evaluate their statistical and engineering analysis according to Korean Industrial Standards(KS). And to make didtinction between the poor efficiency and good efficiency models. 5 grades are classified depending on their tested energy efficiency. This year, based on our analysis, MOTIE mandated updated standards for refrigerators, air-conditioners, Incandescent lamps, and fluorescent lamps.

  • The biodegradabilities of surfactants were measured for six kinds of shampoos in domestic market at present, and the phosphates and heavymetals are analyzed. Analysis results show that though they all come up to KS(Korean Industrial Standards), samples containing plenty of AOS and synthetic SLES have the lower biodegradability than the others. We knew the fact that thease smples are petroleum surfactants have the lower biodegradability than surfactants extracted naturally. All of them the contents of phosphates and heavymetals are excellent for limitation of the cosmetic standards.

  • In determining properties of ductile cast iron, it is well known that nodularity plays a significant role. Therefore, the national and/or international standards for ductile cast iron such as KS, ISO, ASTM and JIS have specified some methods for evaluating it. However, most of standards have not recommended the methods using image analyzer which is known as an objective analyzing tool for evaluating microstructure. In this study, a reliable method for evaluating nodularity by image analyzing method was proposed, and the result was compared with that from the common counting method proposed in KS D 4302-1999. It was found that there was a reasonable relationship in nodularities measured by these two methods.

  • Purpose: The purpose of this study is to suggest the modified 'Korean Standard-Quality Excellence Index' model and analyze the improvement effect with survey data by comparing the properness between current and suggested model result. Methods: The collected data through the survey were analyzed using paired t-test and unbalanced ANOVA method for testing the consistency of two customer satisfaction evaluating categories and comparing the current model to suggested model for confirming the improvement of performance. Results: The statistical analysis result shows that adjusted model using prior information improves the consistency between two customer satisfaction in case of short life-cycle product. Also long life-cycle product case, the result shows difference gap decreasing with same direction. Conclusion: Considering statistical model for QEI reflecting the characteristic of product group such as life cycle seems to be meaningful. Since index may be compared yearly base for checking the trend, careful approaching without big change should be considered for application.

  • 한국산업표준(KS)은 발포 플라스틱 제품에 대하여 소형화염에 의한 수평 연소성의 측정 방법 및 시험절차를 규정(KS M ISO 9772:2018)하고 측정 결과에 대한 압출법 단열판(이하 XPS)의 자기소화성과 관련한 성능 및 기준을 KS 규격(KS M 3808:2020)에서 규정하고 있다. KS 규격에 적합함을 인증 받은 제품은 연소성(이하 '자기소화성')을 가지고 있어야 함에도 공사현장에서 용접불티 등에 의해 착화 및 확산되어 대량의 인명과 재산 피해가 발생하고 있는 실정이다. 본 연구에서는 KS 인증을 받고 시중에 판매 중인 5개사의 XPS 단열재를 구입하여 공사현장에서 발생되는 용접불티에 의한 착화 및 확산 여부를 실험하였다. 실험결과, 5개사의 제품 중 3개사는 성능의 차이는 있으나 자기소화성이 있는 것으로 확인되었으나, 2개사는 쉽게 착화 및 확산되어 자기소화성이 있다고 보기 어려웠다. 동종의 제품에 대하여 KS 규정에 따른 실험결과, 용접불티에 의해 착화되었던 제품 2종을 포함한 총 3종의 제품이 KS M 3808에서 규정한 자기소화성이 없는 것으로 확인되었다.

  • 화학 산업의 발전에 따라 관련 사고가 빈번하게 발생하고 있으며 그 가운데 화재·폭발 사고가 큰 비중을 차지하고 있다. 화재 · 폭발 사고를 방지하기 위해 인화성액체를 취급하는 장소 등은 관련 법령에 근거하여 한국산업표준(KS C IEC60079-10-1)에 따라 폭발위험장소를 구분하도록 하고 있다. 이는 인화성액체를 취급하는 연구실에도 동일하게 적용된다. 본 논문에서는 연구실에서 인화성액체가 누출되어 증발 풀(pool)을 형성하는 경우 한국산업표준에 따른 폭발위험장소 구분 절차의 적용성과 환기속도의 변화가 누출특성에 미치는 영향을 확인하였다. 이를 통해 연구실과 같은 장소는 한국산업표준에 따른 폭발위험장소 구분에 대한 기준적용이 어려우며, 별도의 안전대책이 마련되어야 함을 알 수 있었다.
