Final answer:
Bonding receptacles are tested using a psi spring scale to check if they can sustain a specified pull force safely. The standard force used in an example is 2.50 N, which is about half a pound of force over 100 meters of wire and is generally not a structural concern. The psi is a common unit of pressure, and precise readings are essential.
Step-by-step explanation:
The question refers to the inspection of bonding receptacles using a psi spring scale to measure the pull force. Inspection standards require that receptacles are tested to determine if they can withstand a certain amount of force without becoming detached or damaged. While the question does not provide an exact value, an example is given with a reference to a force of 2.50 N (Newtons), which is approximately half a pound of force. This force is applied over 100 meters of wire and is considered to be much lower than the weight of the wire itself, indicating that it doesn't cause concerns in terms of the structural integrity of the bonding receptacles or the wire.
When measuring in psi, it's important to pay attention to the graduation marks on the measuring instrument to ensure accurate readings, reported to three significant figures. The symbol psi stands for "pounds per square inch" and is a unit of pressure commonly used to gauge various types of forces, including the air pressure in tires.
