§ 4029.2. N. Notes.
Currentness
N.1. Test Liquid. The test liquid shall be carbon dioxide in a compressed liquid state.
N.2. Vaporization and Volume Change. Care shall be exercised to reduce vaporization and volume changes to a minimum. When testing by weight, the weigh tank and transfer systems shall be precooled to liquid temperature prior to the start of the test to avoid the venting of vapor from the vessel being weighed.
N.3. Test Drafts.
N.3.1. Gravimetric Test. Weight test drafts shall be equal to at least the amount delivered by the device in two minutes at its maximum discharge rate.
N.3.2. Transfer Standard Test. When comparing a meter with a calibrated transfer standard, the test draft shall be equal to at least the amount delivered by the device in two minutes at its maximum discharge rate.
N.3.3. Volumetric Prover Test Drafts. Test drafts shall be equal to at least the amount delivered in one minute at normal discharge rate.
N.4. Testing Procedures.
N.4.1. Normal Tests. The “normal” test of a device shall be made at the maximum discharge flow rate developed under the conditions of installation. Any additional tests conducted at flow rates down to and including one-half of the sum of the maximum discharge flow rate and the rated minimum discharge flow rate shall be considered normal tests.
N.4.2. Special Tests. Any test except as set forth in N.4.1. shall be considered a special test. Tests shall be conducted, if possible, to evaluate any special elements or accessories attached to or associated with the device. A device shall be tested at a minimum discharge rate of:
(a) not less than the minimum rated capacity or 20 percent of the maximum rated discharge rate of the device, whichever is less, or
(b) the lowest discharge rate practicable under the conditions of installation.
“Special” tests may be conducted to develop any characteristic of the device anticipated under the conditions of installation as circumstances require.
N.4.3. Density. Temperature and pressure of the metered test liquid shall be measured during the test for the determination of density or volume correction when applicable. Table 1, contained in this Article, shall apply.
N.4.4. Automatic Temperature or Density Compensation. If a device is equipped with an automatic temperature or density compensator, the compensator shall be tested by comparing the quantity indicated or recorded by the device (with the compensator connected and operating) with the actual delivered quantity. Table 1, contained in this Article, shall apply.
