Resumen del asunto	Existe un problema con los Out-of-Service Criteria de América del Norte y el 49 CFR en lo que respecta a las uniones en las mangueras de freno. En la Parte II del apartado 4 del OOSC, Sistema de Frenos, g. Manguera/Tubo de Freno, (4), se indica: "Uniones incorrectas, como una unión realizada deslizando los extremos de la manguera sobre un trozo de tubo y sujetando la manguera al tubo con una abrazadera (393.45(a))". Consulte el 49 CFR 393.45(a) y no encontrará ninguna referencia a esta práctica como prohibida. Si bien se menciona la infracción en el Apéndice G, no podemos aplicarla, y el OOSC entra en conflicto directo con la normativa.
Justificación o necesidad	Esto debe aclararse y corregirse, ya sea como una enmienda al OOS o volviéndolo a colocar en el reglamento (393.45(a), como una acción prohibida, como estaba allí hasta hace poco.
Solicitud de acción	Solicitamos que se aclare esta cuestión y que se brinde la orientación adecuada al personal sobre este tema.
Medidas adoptadas por el comité	Prior to August 15, 2005, 49 CFR 393.46 (f) stated the following (f) Splices in tubing if installed on a vehicle after March 7, 1989, must use fittings that meet the requirements of SAE Standard J512-OCT 80 Automotive Tube Fittings or for air brake systems SAE J246--March 81 Spherical and Flanged Sleeve (Compression) Tube Fittings as found in the SAE Handbook 1985 edition.
