This revision of the document reflects a number of changes agreed to at the last two G12 Fluids meetings in Lisbon and Montreal. Among the revisions are the addition of a warning statement about fluid compatibility with carbon brake material (1.3.8), changes to the fluid shearing procedure (3.3.4.1), insertion of a cold plate foam test (3.3.5), a change to the requirements for periodic testing (4.2.2), and new requirements for fluids containing recycled glycol (4.4.2.1). A number of other editorial revisions have also been incorporated into the document to improve clarity.
