Abstract: PROBLEM TO BE SOLVED: To perform a cracking test simply and safely, by putting metal sulfide powder on a sealing test piece on which stress more than yield stress is impressed, keeping it in saturated vapor atmosphere for a given period, and then observing crack of the test piece. SOLUTION: A sealing test piece 7 is sensitized, is impressed by stress about 1-1.5 times more than yield stress with a clamping tool 9 to increase its cracking speed, and is put on the supporting table 6 in the box 4. About 10-15g ferrous sulfide powder 8 kneaded with demineralized water is placed on the sealing test piece 7, demineralized water 5 is poured into the box 4 until the lower side of the supporting table 6, and this condition is kept for about one or two weeks at about 30 deg.C under a saturated vapor pressure. After that, the sealing test piece 7 is taken out from the box 4, washed with water satisfactorily, wiped water off, and visually checked whether crack exists on the part from which the ferrous sulfide powder 8 is removed. When cracks are not founded out, the surface is inspected by a stereo microscope.  When cracks are not founded out yet, the sealing test piece 7 is cut off and its cross section is inspected by an optical microscope. Thus, a polythionic acid crack is precisely evaluated.
