Line 3 and 4 with the label Pr stand for?

• A. Puncture resistance
• B. Pressure rating
• C. Plasticity
• D. Priming status

Answer: (A)

When you see the label Pr on lines like 3 and 4, it refers to puncture resistance. This is a safety-related material property commonly noted in product specs and audits to show how well the material can resist being pierced by sharp objects. Puncture resistance is especially important for protecting workers from nails, wires, and other sharp hazards.

The other options don’t fit typical labeling in this context: a pressure rating would pertain to systems dealing with fluids or gases; plasticity is about how a material deforms, and is not usually abbreviated as Pr on such lines; priming status relates to coatings preparation and wouldn’t be labeled Pr.
