Introduction to ASTM E144
ASTM E144 determines the soundness of both new and used oxygen combustion vessels and outlines safety measures that must be taken when using these devices. ASTM E144 can be used for any operation where samples are burned in a metal bomb with oxygen under pressure until they are oxidized. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E144 tests for our clients.
ASTM E144 Test Method
Hydrostatic Test Method
| Setting up the vessel | The vessel is completely emptied of all air and filled with water at room temperature, which is attached to the required hydraulic pressure pump. The water pressure applied to the system is 1.5 times the pressure of the vessel pressure. |
| Measuring the diameter | After setting up the pressure at atmospheric pressure, the central diameter of the vessel cylinder is measured. Similar readings are taken after raising the hydrostatic pressure, after which it is released again and another set of measurements is made. |
ASTM E144 Test Specimens
| Specimen Detail | Oxygen combustion vessels are the test specimens for ASTM E144. In this practice, hydraulic pressure chambers are used to assess leaks in the vessel so that the vessels can be regarded as safe or unsafe. |
| Specimen Size | The total mass of the ignitable material that is present should not be greater than the maximum energy release. |
ASTM E144 Test Result
ASTM E144 effectively tests the safety of oxygen combustion vessels using the hydrostatic testing technique. If there is a deflection of more than o.005 inches at the center of the vessel cylinder after applying pressure, or if any part of the vessel does not return to its original shape, then the vessel is considered unsafe and is rejected.
