During the initial portion of the hydrostatic test, the safety valve and steam gauge may be left in place to see if they function properly up to a maximum of 10 percent over the MAWP calculated by the formula in § 61:08:09:13 or they may be removed and tested separately. For hydrostatic pressures greater than 110 percent of the MAWP, the steam gauge and the safety valve must be removed. The safety valve spring may not be compressed to prevent the valve from opening.
