0 mytt x lim) was folded into a U-shape and packaged, and tested for 21 cycles (3 weeks) under the following conditions.
鋼板をコの字に折り曲げたのは、鋼板が防錆紙に接触す
る面を接触防錆性能について、また、非接触面は気相防
錆性能について試験するためである。The reason why the steel plate was bent into a U-shape was to test the surface of the steel plate in contact with the anticorrosion paper for contact rust prevention performance, and the non-contact surface to test for vapor phase rust prevention performance.
試験条件 「５°Ｇ 、 ９０ ％ＲＨ、３ｈｒｊ−「５０℃。Test condition "5°G, 90% RH, 3hrj-"50°C.
９５％ＲＨ、３ｈｒＪ−ｒ ５℃、９０％ＲＨ。95% RH, 3 hr J-r 5°C, 90% RH.
２ｈｒＪ−「５０℃、 ９５％ＲＨ、１６ｈｒＪを１サ
イクルとする。2hrJ - 50°C, 95% RH, 16hrJ is one cycle.
