Abstract

The performance evaluation of cold weather clothing is mainly carried out with thermal resistance. However, the results of the revised test method regarding the same specimen were decreased compare to previous one. In addition, there were deviations of the results among the authorized testing institutes according to the different interpretation of the KS test method. This makes it a considerable difficulty to the quality assurance of combat supplies. The purpose of this study is to minimize the variation of the results before and after the revision by analyzing the cause of the decrease in the heat insulation rate according to the revised test method. For this purpose, the difference between the test conditions before and after the revision of KS is analyzed and the possible results are reviewed. In addition, we want to minimize the result deviation between testing laboratories by analyzing the cause of the result deviation between test laboratories according to arbitrary interpretation of the standard. Based on this, we propose a standardized test method to prevent the decrease of the heat insulation rate by checking the pre-revision test method and the condition with the least deviation.

동절기 방한복의 성능 평가는 주로 열 저항으로 이루어지고 있다. 그러나, 이를 측정하기 위한 KS가 개정되면서, 동일한 표본의 시험결과가 개정 결과에 비하여 감소하는 결과를 초래하였다. 또한, 공인 시험기관마다 변경된 시험 절차 대한 해석의 차이가 발생하여 시험 기관 간에 결과 편차도 크게 발생하고 있으며, 이로 인해 군수품의 품질보증에 상당한 애로가 되고 있다. 따라서 본 연구에서는 개정된 시험방법에 따른 보온율 감소 현상의 원인을 분석함으로써, 개정 전과 후의 결과 편차를 최소화하고자 한다. 이를 위해 규격의 개정 전과 개정 후의 시험 조건의 차이와 이로 인해 발생 가능한 결과를 검토한다. 또한, 규격의 임의해석에 따른 시험 기관간 결과 편차 발생의 원인을 분석함으로써 시험 기관간의 결과 편차를 최소화 하고자 한다. 이를 바탕으로 개정 전 시험 방법과 편차가 가장 적은 조건을 확인하여 보온율 감소 현상을 예방하기 위한 표준을 제시하고자 한다.
