What is the minimum flexural strength of a fiberglass tank?

  1. 15,000 PSI

  2. 19,000 PSI

  3. 20,000 PSI

  4. 25,000 PSI

The correct answer is: 19,000 PSI

The minimum flexural strength of a fiberglass tank is particularly important because it indicates the tank's ability to withstand bending forces without failing. This property is crucial in ensuring the structural integrity of the tank when it is in use and exposed to various pressures and environmental conditions. A flexural strength of 19,000 PSI is a standard that ensures the tank can handle the expected loads during its operational life while providing durability and longevity. Tanks that meet or exceed this strength are generally regarded as suitable for holding wastewater and other materials, reducing the likelihood of failure. This threshold helps ensure that installations can occur safely and in compliance with relevant standards and regulations.
