방범유리의 저항성을 검증하고 이를 표준화할 수 있도록 연구를 진행하였고, 이에 따라 딱딱한 물체에 대한 충격은 “낙구 충격 시험”으로 온도조건이 추가된 딱딱한 물체와 날카로운 물체의 충격은 “내열성 충격 시험”으로 구분하여 방범유리 성능 평가항목을 선정하였다. 성능평가 결과 일반 단층유리들은 방범에 매우 취약한 것을 확인할 수 있었다. 최소 1등급 이상의 성능을 발휘하기 위해서는 10T 이상의 강화유리를 사용하여야 되며, 그 이하의 제품으로는 방범역할을 기대하기 힘들 것으로 판단된다. 또한 일반 접합유리의 경우 유리의 두께가 두꺼우면서 필름의 두께도 두꺼운 제품들은 대체적으로 높은 등급에 속하였으나 필름 두께가 너무 두꺼워 주거용 창이나 문에는 적합하지 못한 제품들이었다. 결론적으로 방범유리는 성능 향상을 위해서는 유리 자체의 강도도 중요하지만 부가적으로 사용되는 필름 및 레진의 강도와 두께가 그 제품의 성능을 결정한다고 해도 과언이 아닐 것이다. 현재 국내 실정으로 볼 때, 앞에서 제시한 낙구 충격 시험과 내열성 충격 시험의 평가 방법 및 등급 설정은 범죄예방 목적 및 국내 유리 제품 현황들을 잘 반영하고 있어 적합한 시험법으로 판단되며, 추후 꾸준한 제품개발과 국내 여건 변화에 발맞추어 시험 방법 강화 및 등급 상향을 통해 지속적 적용이 가능할 것으로 판단된다.
While many studies have been conducted on crime prevention hardware, there has been a relative lack of research on security and crime prevention glass. In order to establish performance evaluation items of security glass, the research reviewed domestic industry trends, technology development conditions, and current technology level in various ways based on CPTED analysis and international standards, and developed evaluation methods to enable evaluation of various applied products such as banks, expensive product retailers, and security buildings that require high performance as well as relatively low crime prevention functions. The development of the evaluation method was conducted to verify and standardize the resistance of the security glass to external impacts. Accordingly, the impact of the rigid object was selected by dividing the impact of the rigid object and the sharp object with the temperature condition by the "falling impact test" into the "heat-resistant impact test". Performance tests have shown that general fault glass is highly vulnerable to crime prevention. In order to perform at least 1st grade, a minimum of 10T of tempered glass must be used, and it is judged that it is difficult to expect a crime prevention function for products below that. Also, in the case of general junction glass, products with thick glass and thick film thickness generally belonged to a higher grade, but the film thickness was too thick to fit for residential windows or doors. High-grade, thin-thick products are currently difficult to produce with domestic technology, and more research and development by production companies is needed. In conclusion, the strength of the glass itself is important to improve performance, but it is no exaggeration to say that the strength and thickness of the film and resin used additionally determine the performance of the product. Given the current domestic situation, the above-mentioned methods and grading of fall impact tests and heat-resistant impact tests are considered suitable test methods as they reflect the current status of domestic glass products and the purpose of crime prevention, and it is judged that they will be able to be applied continuously in the future by strengthening test methods and upgrading grades in line with steady product development and changes in domestic conditions. The establishment of the certification system will lead to the activation of related research and the securing of the quality of the products, which will bring about the development and economic effects of related industries, contribute to the localization of products and technologies through the use of established standards, and actively respond to the growing demand for safety through the commercialization of development technologies to secure global competitiveness.
