CISPI stands for which of the following?

• A. Cast iron soil pipe association
• B. Cast iron soil pipe industry
• C. Cast iron soil pipe technical council
• D. Cast iron soil pipe institute

Answer: (D)

Knowing what CISPI stands for helps you map the acronym to the organization that sets standards for cast iron soil pipe. CISPI stands for Cast Iron Soil Pipe Institute. This formal body develops and maintains standards, test methods, and technical guidance for cast iron soil pipe and fittings used in drainage systems. The other options—association, industry, or technical council—sound plausible but don’t reflect the official name; “Institute” signals a formal organization focused on standards and technical work, which is why it’s the correct expansion. In practice, CISPI standards are referenced in codes and product specs, so recognizing the correct name helps you connect the material to the governing guidelines.
