(a) Each transfer pipeline system and mechanical loading arm must not leak when undergoing an SLPT of at least 125 percent of the maximum allowable operating pressure.

(b) The pressure tests required by this section shall be conducted in accordance with Part 195 of Title 49 of the Code of Federal Regulations as in effect on October 1, 1996, except that an additional four-hour leak test under Section 195.303 of Title 49 of the Code of Federal Regulations as in effect on October 1, 1996, shall not be required.

(c) A deadweight gauge capable of measuring to one-pound-per-square-inch (psi) increments shall be used during each pressure test. The deadweight gauge shall be calibrated to a standard directly traceable to the National Institute of Standards and Technology at least once every two years and shall have a valid Certificate of Traceability.

(d) Test Temperature Data.

(e) Where different sections of a pipeline or pipeline system are located in considerably different environments (e.g., in the open air or below ground or water), the temperature of each segment in each environment shall be monitored separately. For the purposes of pressure compensation calculations due to temperature variations, each segment's temperature in its respective environment shall be used. The total pipeline or pipeline system temperature change shall be determined by adding the temperature change of each segment and prorating the segment's length to the total pipeline length or pipeline system length. Alternatively, each segment in its respective environment may be treated as a separate pipeline under test and the compensated pressure variations due to each segment's temperature variations may be added to arrive at the system pressure variation.
