  1. Hi, According to EN 1634-1:2014, the furnace temperature will reach 1000 degrees Celsius after 60 minutes, if melting point of brass is 900 degrees Celsius how cylinders are supposed to maintain its integrity during the test? Many European third party labs will require that doors during the test to have double cylinder in order to achieve successful EI90 or EI180 doors. Anybody has a solution to this problem?
