What are building commissioning services?
Building Commissioning is the professional practice that ensures buildings are delivered according to the Owner’s Project Requirements (OPR). Buildings that are properly commissioned typically have fewer change orders, tend to be more energy efficient, and have lower operation and maintenance cost.
What is the difference between commissioning and testing?
Commissioning is a SYSTEMATIC process, not a functional testing EVENT. Commissioning is not functional testing. It is a systematic process. Commissioning encompasses everything from OPR/BOD/Design reviews to functional testing and post-occupancy/off season testing.
What is pre-commissioning procedure?
Pre-commissioning (PC) is a construction procedure that includes checking the functional operability of elements within the system in order to ensure the system is ready for commissioning start-up. Protecting equipment before commissioning from normal weather conditions or damage.
What is a commissioning test?
Commissioning test means a test applied to a distributed generation facility by the applicant after construction is completed to verify that the facility does not create adverse system impacts and performs to the submitted specifications.
What is hot testing builders risk?

What is R1 and R2?
R1 = resistance of phase conductor ie Live. R2 = resistance of cpc ie earth.
Is R1 R2 a dead Test?
The highest recorded value is the value of (R1+R2) for the circuit. For detail see page 36-37 GN3. This is a Dead Test – so Safe Isolation is Required • This test verifies that the insulation of conductors and accessories is satisfactory and that the insulation is not in any way defective.
What does R1 stand for?
| Acronym | Definition |
|---|---|
| R1 | Release 1 |
| R1 | Region 1 (DVD region releases) |

| R1 | Research1 (designates a top research university) |
What does the R1 R2 test prove?
The R1+R2 test proves that the phase and earth connections in the circuit are sound. Its merits lie in it being a very low current dc test. If the connections are suspect and there is (for example) a layer of oxide formed over the terminations, it will give you a true high resistance.
Should R1 R2 be lower than Zs?
Zs=Ze+(R1+R2) well not in this case. Just not come across such a difference before that Zs has been so much lower than Ze+(R1+R2)….See Also:
