True or False: 8"-10" inside diameter polyethylene tubing must meet ASTM F667-06 standards.

The correct response is true because ASTM F667-06 specifically outlines the standards for the design, material, and performance characteristics of polyethylene tubing that is used in applications such as drainage and septic systems. The specification ensures that the tubing can withstand specific environmental and mechanical stresses, thus providing reliable service over time.

In the context of septic systems, which are subject to various pressures and environmental conditions, adhering to these standards is critical for maintaining system integrity and preventing failures that could lead to environmental contamination. The requirement for an 8"-10" inside diameter polyethylene tubing to meet these standards emphasizes the importance of using materials that comply with recognized industry benchmarks to ensure safety and performance across different applications.

Options indicating variability based on thickness, or claiming it’s not applicable, would ignore the established regulatory framework that governs the installation and performance of these materials in septic and drainage applications. Therefore, adhering to ASTM F667-06 is essential for ensuring compliance and performance in septic systems.
