Abstract

Blast-resistant doors are among the most critical materials used to protect personnel, equipment, supplies, and information within buildings from explosions caused by conventional weapons, nuclear events, gas, and other threats. However, certifying all types of blast-resistant doors installed in protective facilities through explosive proof testing poses significant challenges. For blast-resistant doors that deviate from the original specifications, product certificates are issued based on expert review. However, inconsistencies in certification standards often arise due to the subjective technical judgments of experts. This study establishes certification standards within the range where the structural behavior characteristics of blast-resistant doors remain unchanged. Specifically, the permissible dimensions for review were defined to ensure that the structural bending behavior of these doors under explosive loads remains consistent. This approach enables project managers to either apply for a product certificate or prepare for explosive proof testing in advance. Additionally, minor modifications, such as automation, were clearly defined to better address on-site demands. For the continuous improvement of the domestic certification system for blast-resistant doors, the study highlights the necessity of implementing a robust management framework for certification drawings. It also underscores the importance of establishing a dedicated explosion-proof testing facility capable of certifying products with various protection levels exceeding 100 bar.

방폭문은 재래식 무기나 핵 혹은 가스 등의 폭발로부터 건물 내부의 인원, 장비, 물자, 정보 등을 보호하기 위해 설치하는 가장 중요한 방호자재 중 하나이다. 그러나, 방호시설에 설치되는 모든 형태의 방폭문을 폭발실증시험을 통해 인증하기에는 제한된다. 인증규격과 상이한 방폭문은 전문가 심의를 통해 제품확인서를 발급하고 있으나, 전문가의 주관적 기술판단에 의해 인증가능 규격에 차이가 존재한다. 이에 본 연구에서는 방폭문의 구조적 거동 특성이 변화되지 않는 범위내에서 인증가능 규격을 설정하였다. 특히, 방폭문이 폭발하중에 휨거동하는 구조적 특성이 변하지 않는 범위 내에서 심의가능 크기를 설정함으로써, 사업관리자로 하여금 제품확인서를 신청하거나 폭발실증시험을 사전에 준비할 수 있도록 하였다. 또한, 자동화 등 경미한 변경사항에 대해 정의함으로써 현장의 수요를 충족할 수 있도록 하였다. 더불어 국내 방폭문 인증제도의 지속적인 발전을 위해서는 인증도면에 대한 관리체계와 100 bar 이상의 다양한 방호등급의 제품인증이 가능한 전용 폭발실증시험장 확보의 필요성도 제기되었다.
