1.1 This practice, 3,4 known as the embrittlement-detector method, covers the apparatus and procedure for determining the embrittling or nonembrittling characteristics ofthe water in an operating boiler. The interpretation of the results shall be restricted to the limits set forth in 8.6.
N OTE 1—Cracks in a specimen after being subjected to this test indicate that the boiler water can cause embrittlement cracking, but not that the boiler in question necessarily has cracked or will crack.
