Abstract
Typically, the design of fire doors on ships is mainly to meet thermal requirements, while thermal deformation can also significantly affect the safety performance of the door. When the fire temperature is high, the door tends to warp and deviate from the supporting frame due to uneven temperature distribution, which may lead to the spread of fire and smoke on ships. To evaluate their performance, fire doors must undergo a standardized fire test. Realistic simulation of this fire test can be of great benefit during the design phase in order to reduce the number of prototypes to be manufactured and tested. This article researches the testing process of A60 fire-resistant doors installed on ships. The A60 fire-resistant door consists of two steel plates, each measuring 1600x600x45 mm, with a 42 mm thick layer of mineral wool insulation placed between them. Test samples were heated in a gas-fired furnace for 60 minutes. The findings are given in the form of a temperature-time chart showing that the test samples meet the requirements for fire-resistant doors used for ships. This study holds significant importance for the development of the shipbuilding industry in Vietnam in the near future.
