Hot-poured compound for clay or concrete sewer pipe shall not be water absorbent and when poured against a dry surface shall have a bond of at least _____ psi. The compound shall not soften sufficiently to destroy the effectiveness of the joint when subjected to a temperature of 160 degrees Fahrenheit. Each joint shall be poured in one operation until the joint is filled. Joints shall not be tested until ___ hour/s after pouring.

50, 2
75, 1
100, 1
125, 2

The correct answer is: 100, 1

The correct choice indicates that the hot-poured compound for clay or concrete sewer pipe must maintain a minimum bonding strength of at least 100 psi when poured against a dry surface. This ensures that the joint remains secure under pressure and is effective in preventing leaks. Additionally, the requirement stipulates that the joints shall not be tested until at least one hour after pouring to allow sufficient time for the compound to adequately cure and bond. This combination of a strong bond and a proper curing time is critical to upholding the integrity of the piping system, ensuring that it can withstand the necessary operational conditions without failure. The specification regarding temperature resistance also highlights the importance of the compound's stability in high-heat environments, which is crucial for long-term reliability.
