This standard establishes the dimensional and visual quality requirements, lot requirements, and packaging and labeling requirements for back-up rings machined from AMS3678/1 polytetrafluoroethylene materials for use in AS5202 ports. It shall be used for procurement purposes.
This SAE Standard specifies processes for the cleaning of metal surfaces to remove any extraneous or undesirable material or deposits at any stage of manufacture, storage or service and for the preparation of these surfaces for further treatment. Any necessary stress-relieving treatments are also included. This Standard does not override special preparatory procedures specified in individual Defence Standards, Defence Specifications, DTD Process Specifications, DG Ships Specifications and Naval Defence Standards. It also does not cover cleaning operations associated with the maintenance of internal combustion engines, the preliminary removal of heavy deposits of oil, grease, or dirt accumulated during operational service, preparations for welding and the cleaning of electrical contacts.
The following list consists of hose data provided as of December, 2019, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25. Where the maximum allowable working pressure (MAWP) or type of fitting is not specified, use the manufacturer's recommended MAWP or type of fitting. This list has been compiled by SAE staff from information provided by the manufacturers whose product listings appear in this document. Manufacturers wishing to list their products in this document shall: a. Successfully test their hose to the requirements of SAE J1942, Table 1. b. Submit a letter of certification to the SAE J1942 test requirements for each specific type of hose tested (see sample table, Table 1) along with the test results. All sizes should be included in the same letter which must also include all of the information necessary to make a SAE J1942-1 listing. c.
