Product Code:SAE J1942/1
Title:Qualified Hoses for Marine Applications
Issuing Committee:Hydraulic Hose And Hose Fittings Committee
Scope:Effective August 28, 1991, the SAE replaced the USCG as the listing agency for Marine Hose Assemblies. The previous USCG list was discontinued as of December 31, 1992, and is being replaced by this SAE listing, J1942-1.All products appearing on the USCG list as of December 31, 1992, may be carried over to the SAE J1942-1 provided they meet the new test requirements listed in SAE J1942.If your products comply, you may retain your listings with no additional testing. (Please note that the USCG has the authority to request and inspect your test results at their discretion.)The following list consists of hose data provided as of May 2003, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25(c). 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:Successfully test their hose to the requirements of SAE J1942, Table 1.Submit a letter of certification to the SAE J1942 test requirements for each specific type of hose tested. 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.The SAE will review the letter and may, at their discretion, request to see some, or all, of the test results. A copy of the submittal letter marked 驴Accepted For Listing驴 will be returned to the applicant and a duplicate copy sent to the USCG.The cutoff date for inclusion of a hose listing in the annual SAE Handbook is April 30, of the preceding year. However, listed hoses may be used on vessels as soon as the 驴Accepted For Listing驴 letter is issued by the SAE.Next publication of this listing is scheduled to take place on December 2003. If you wish to include additional hoses in the 2003 publication of this list, please submit your Certified List to SAE Headquarters by October 2003.
