Abstract : The MIL-PRF-23699 specification has contained a foaming requirement since its inception in 1966. Recent batch acceptance tests on qualified oils (2008-present) have failed to meet the unique MIL-PRF-23669F foam stability requirement which has increased the focus on the test results and validity. In order to understand the factors that contribute to foam stability a literature review was conducted on the structure of foam as well as prevalent mechanisms of foam stability and collapse. Foaming is a broad subject across various industries and materials. The literature search serves to consolidate the information from numerous sources to provide a basic foundation for the physics of foam stability and collapse
