Hydrostatic testing on extinguishers is typically performed at what intervals and what does it verify?

Hydrostatic testing checks the physical strength of the extinguisher’s cylinder by pressing it with water to a specified pressure. The goal is to reveal any thinning walls, cracks, or corrosion that could lead to a catastrophic failure in service. Because the stability of the cylinder depends on its material and construction, the test is done at intervals ranging roughly from five to twelve years, depending on the type of cylinder and the standard used. After the test, the cylinder is dried, reassembled, and the extinguisher is recharged and recertified as needed. This isn’t about checking weight or appearance like color. It’s a safety check of the vessel itself to ensure it can safely withstand the pressures it’s expected to encounter during use.
