{"abstract":"This NPRM proposes to amend FMVSS No. 116, Motor Vehicle Brake Fluids, so that brake fluids would be tested with ethylene, propylene, and diene terpolymer (EPDM) rubber, as this type of rubber is increasingly being used in brake fluid seals. This NPRM also updates references to standards issued by the Society of Automotive Engineers (SAE) and the American Society for Materials and Testing (ASTM) (no substantive changes to the standard would be made by these updates), and corrects minor errors in the standard.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"National Highway Traffic Safety Administration","name":"National Highway Traffic Safety Administration","id":345,"url":"https://www.federalregister.gov/agencies/national-highway-traffic-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/345","parent_id":492,"slug":"national-highway-traffic-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2010/02/03/2010-1958.html","cfr_references":[{"chapter":null,"citation_url":null,"part":571,"title":49}],"citation":"75 FR 5553","comment_url":null,"comments_close_on":"2010-04-05","correction_of":null,"corrections":[],"dates":"Comments must be received on or before April 5, 2010.","disposition_notes":null,"docket_ids":["Docket No. NHTSA-2010-0012"],"dockets":[],"document_number":"2010-1958","effective_on":null,"end_page":5560,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2010/02/03/2010-1958.xml","html_url":"https://www.federalregister.gov/documents/2010/02/03/2010-1958/federal-motor-vehicle-safety-standards-motor-vehicle-brake-fluids","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2010-1958?publication_date=2010-02-03","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2010-02-03/2010-1958/mods.xml","not_received_for_publication":null,"page_length":8,"page_views":{"count":5226,"last_updated":"2026-10-25 02:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2010-02-03/pdf/2010-1958.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2010-02-03","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2010/02/03/2010-1958.txt","regulation_id_number_info":{"2127-AK58":{"issue":"201810","html_url":"https://www.federalregister.gov/regulations/2127-AK58/fmvss-116-upgrade-rubber-for-brake-fluid-testing","title":"FMVSS 116, Upgrade Rubber for Brake Fluid Testing","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201810&RIN=2127-AK58&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2127-AK58"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2010-02-03T16:02:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":5553,"subtype":null,"title":"Federal Motor Vehicle Safety Standards; Motor Vehicle Brake Fluids","toc_doc":"Motor Vehicle Brake Fluids","toc_subject":"Federal Motor Vehicle Safety Standards:","topics":["Imports","Motor vehicle safety","Motor vehicles","Tires"],"type":"Proposed Rule","volume":75}
