No, and this is the requirement almost every gas test form omits. IFGC 406.4 says mechanical gauges used to measure test pressures "shall have a range such that the highest end of the scale is not greater than 5 times the test pressure." Turn that around and it is a floor on where your reading sits: the test pressure has to land at or above one fifth of full scale. A 3 psig test therefore needs a gauge reading to 15 psi or less — the 0-30 psi gauge most people reach for is already non-compliant for it, and a 0-100 psi gauge puts a 3 psig test at 3 percent of span, inside the width of the needle. The pipe can bleed down measurably and the needle will not visibly move. That is the whole point of the clause: it forces the test onto an instrument where a drop is legible. This report asks for the gauge's full-scale range and scores it against the pressure you actually pulled, so a test read on the wrong instrument is called out instead of being recorded as a pass. The rule is written against mechanical gauges, so a manometer — which 406.4 expressly permits — is not judged by it, and a digital gauge gets an advisory rather than a failure.

Usually in practice, but that is not what the code says, and knowing the difference matters when an inspector asks what you tested to. IFGC 406.4.1 sets a floor, not a fixed value: "not less than 1.5 times the proposed maximum working pressure, but not less than 3 psig, irrespective of design pressure." For an ordinary 7 in. w.c. system, 1.5 times working pressure is about 0.38 psig, so the absolute minimum governs and the code answer is 3 psig. Duration is a floor too, and it is the one place the two model codes genuinely disagree: IFGC 406.4.2 scales with the system — half an hour per 500 cubic feet of pipe volume or fraction thereof, 10 minutes minimum under 10 cubic feet, never required to exceed 24 hours — while IRC G2417.4.2 drops the volume term and says a flat 10 minutes. So where does 10 psi for 15 minutes come from? Local amendments. Denver amends 406.4.1 to 10 psig, Minnesota to 25 psig, Mountain Village CO to 15 psi for 20 minutes — all amendments to the same sentence. Every one of them is enforceable where it is adopted. This report scores against the code by default and lets you enter your AHJ's figure instead, then prints both so the reader can see which number the verdict used.

Under the code, 3 psig for a normal 7 in. w.c. system — IFGC 406.4.1 and IRC G2417.4.1 both require not less than 1.5 times the maximum working pressure but never less than 3 psig, and 1.5 times 7 in. w.c. is far below that floor. In practice your jurisdiction may require more: Denver amends the floor to 10 psig and Minnesota to 25 psig. Check before you pull the test, then enter the local figure in this report so the verdict is scored against the number that will actually be enforced.

Yes, and closing a valve is not a substitute. A line, service or appliance regulator is built for inches of water column; test pressure ruptures the diaphragm or blows the internal relief. IFGC 406.3.3 does not use the word "regulator" — it describes equipment "designed for operating pressures of less than the test pressure", which is exactly what a regulator is, and requires that it be isolated by disconnecting it and capping the outlet. IFGC 406.3.4 is the rule for the other case: equipment rated at or above the test pressure may be isolated by closing its individual shutoff valve. Equipment simply excluded from the test is disconnected or blanked under 406.3.2. This report puts all three on a pre-test isolation list and prints anything you did not confirm.

No on both counts. IFGC 406.2 permits air, nitrogen, carbon dioxide or an inert gas, and states in capitals that oxygen shall never be used — oxygen in a line carrying hydrocarbon residue is an ignition source, not a test medium. Testing on fuel gas defeats the purpose of a pressure test and is not among the permitted media. The report records the medium and flags oxygen as an error rather than accepting it quietly.

It depends which code governs. Under IFGC 406.4.2 the hold is half an hour for each 500 cubic feet of pipe volume or fraction thereof, with a 10 minute minimum below 10 cubic feet and no requirement to exceed 24 hours — so a small house line is 30 minutes once volume reaches 10 cubic feet, and a 600 cubic foot system is an hour. Under IRC G2417.4.2, which covers one- and two-family dwellings, it is a flat 10 minutes. Local amendments override both. Choose the code basis at the top of the report and enter the pipe volume, and the required hold time is derived and printed with the reasoning.

Any loss of pressure over the hold. IFGC 406.5 requires the system to withstand the test pressure "without showing any evidence of leakage or other defects" and deems any reduction indicated by the gauge to be a leak unless the reduction can be readily attributed to another cause — a large temperature swing being the usual legitimate one. The same section requires the affected piping to be repaired or replaced and retested, which is why every section on this report carries a repairs note and a full retest row rather than a single pass/fail box. A section that failed, was repaired and then held prints the retest as the deciding result with the original failure still on the record.

No. It records the readings you entered and scores them against the code sections cited on it. The authority having jurisdiction accepts or rejects the piping, and its inspector may test again. Test pressure, hold time and gauge requirements are amended locally more often than almost anything else in the fuel gas code, so confirm what is in force before you rely on a verdict — and enter the local figure so the report is scored against it.
