20 Dec NHTSA’s proposal to amend FMVSS. No. to include the latest requirements in the SAE brake hose standards for hydraulic, vacuum, and. 10 Apr FMVSS specifies labeling and performance requirements for motor vehicle brake hose, brake hose assemblies, and brake hose end. With the launch of air brake hose and 25 series crimp fittings it is important to understand the Department of Transportation (DOT) regulation FMVSS

Utilize an impact test apparatus as shown in Figure 8. Title 37 – Patents, Trademarks, and Copyrights.

Utilize test apparatus that is dynamically balanced and includes:. Utilize a inch vacuum brake hose assembly sealed at one end. The vibration test shall be conducted in an environmental chamber and the air temperature shall be cycled between minus 40 degrees Fahrenheit minus 40 degrees Celsius fnvss degrees Fahrenheit degrees Celsius during the test.

Title 31 – Money and Finance: However, a particular tubing assembly or appropriate part thereof need not meet further requirements after having met the constriction requirement S Bend the hose around a mandrel with a diameter equal to five times the initial outside diameter of the hose.

However, a particular hose assembly or appropriate part thereof need not meet further requirements after having met the constriction fvmss S9. The section you are viewing is cited by the following CFR sections. Prepare an air brake tubing assembly with a free length of 6 inches six inches of exposed tubing between the end fittingswith the end fittings installed in accordance with the end fitting manufacturer’s instructions.


Each air brake hose constructed of synthetic or natural elastomeric rubber shall conform to the dimensional requirements specified in Table III, except for brake hose manufactured in metric sizes. The information need not be present on tubing that is sold as part of a motor vehicle. Utilize an air brake tubing assembly or prepare a inch length of tubing and install end fittings according to the end fitting manufacturer’s instructions. Remove the hose and cool it at room temperature for 2 hours.

After 24 hours of exposure to salt spray, a hydraulic brake hose end fitting shall show no base metal corrosion on the end fitting surface except where crimping or the application of labeling information has caused displacement of the protective coating S6.

FMVSS – 4ward Testing

Title 41 – Public Contracts and Property Management. Toc – Table Of Contents Parts – If necessary install adapters on the end fittings to permit quick attachment to the machine, to keep water from entering the tubing assembly, fmvs to ensure that the tubing assembly is in a straight position when installed on the machine.

Nominal hose inside diameter, millimeters 1. Plastic air brake tubing shall not rupture when subjected to 80 percent of the mfvss strength pressure in Table VIII for the size of tubing being tested, after being exposed to ultraviolet light for hours and then impacted with a one pound weight dropped from a height of 12 inches.

Free length means the linear measurement of hose exposed between the end fittings of a hose assembly in a straight position. The designation may consist of block capital letters, numerals or a symbol. Conduct the burst strength test in S Remove the hose from the test cylinder and visibly examine the exterior of the hose for cracks without magnification.


The testing that 4ward carried out was of a high standard, met deadlines and targets that were necessary and we were kept involved with regular updates as the testing progressed.

49 CFR 571.106 – Standard No. 106; Brake hoses.

Remove the plugs from the end fittings. The cylinder is constructed of a non-reactive material or coated to prevent chemical reaction with zinc chloride.

Title 27 – Alcohol, Tobacco Products and Firearms. Aftercyclesset the temperature of 160 environmental chamber to degrees Fahrenheit degrees Celsius. Plastic air brake tubing shall conform to the dimensions in Table VII after conditioning in boiling water for two hours.

SAE J FMVSS – VH | Continental ContiTech

In the case of light duty hose the first application of force shall not exceed a peak value of 50 pounds, and the fifth application of force shall reach a peak value of at least 20 pounds S They do not represent conversions.

Title 38 – Pensions, Bonuses, and F,vss Relief.

The movable attachment point has a cycle rate of cycles per minute. To account for slight out-of-round conditions, diameter measurements may be calculated using the average of the major and minor diameters. A plastic air brake tubing assembly when subjected to a tensile pull test shall either elongate 50 percent fvss withstand the conditioned tensile load in Table VIII without separation from its end fittingswith one end of the assembly conditioned in boiling water for fmvsss minutes.
