Question: 1 / 1030

How often should standard weight high pressure oxygen cylinders be hydrostatically tested?

Every 3 years

Every 4 years

Every 5 years

Standard weight high pressure oxygen cylinders should be hydrostatically tested every 5 years. This is in accordance with the regulations outlined in 14 CFR part 43, appendix A. During the hydrostatic test, the cylinder is filled with water and placed in a test chamber to evaluate the cylinder's structural integrity by measuring its expansion under high pressure. This periodic testing helps ensure that the cylinder remains safe for use in high-pressure oxygen applications.

Options A, B, and D are incorrect because they do not align with the correct frequency of hydrostatic testing for standard weight high pressure oxygen cylinders.
