Purpose: In this paper, the development direction of the blast-proof door verification test was suggested through analysis of the blast-proof door verification test that has been conducted so far. Blast-proof doors are protective equipment that withstands storm pressure from enemy weapons at the outermost part of the build-ing in case of emergency, and must be verified before installation. To ensure the durability and stability of the blast-proof door, the explosion-proof test of the blast-proof door has been conducted four times since 2016. Method: In the meantime, as domestic blast-proof door certified products came out through explosion-proof tests of blast-proof doors, it has opened the way for domestic blast-proof doors to be used instead of expensive overseas products in domestic protection facilities and evacuation facilities. Based on the progress of the last four demonstration tests and certification results, the opinions of the Korea Gas Safety Corporation, the De-fense Installations Agency, and explosion-proof door manufacturers were synthesized to derive improvements. In addition, the explosion-proof door certification procedure and certification standards were reviewed, and the explosion-proof door manufacturing process and documents submitted by the companies that applied for the certification test were reviewed. Results: As a result of reviewing the requests of the host organization and explosion-proof door manufac-turers in the process of preparing the demonstration test such as purchasing TNT, preparing the test site, con-ducting an explosion test, and issuing a certificate, the need for improvement in the implementation of the demonstration test was identified. Improvement needs were identified in the agency in charge of the demon-stration test, the verification method, the method of measuring the displacement of the explosion-proof door after the explosion, and the alternative method of the demonstration test. Conclusion: I suggested that the explosion-proof test of the blast-proof door be supervised by the military institution. Through this, it is expected that the work related to the explosion-proof test will be more efficiently controlled. Also I concluded that it is necessary to supplement the method of measuring the displacement of the blast-proof door, and consider implementing a reduced-scale explosion test. In addition, it is proposed to supplement and develop the blast-proof door blasting demonstration test through computer simulation using the empirical test data accumulated in the future. Once the explosion-proof test of the blast door is improved as suggested in the conclusions, it is clear that the result will be of benefit to the military, companies, and ulti-mately the people who will be provided with certified high-quality blast-proof doors and installed in the protec-tion facilities.
