Each vacuum brake hose assembly or appropriate part thereof shall be capable of meeting any of the requirements set forth under this heading, when tested under the conditions of S13 and the applicable procedures of S Except for brake hose assemblies designed for use with mineral or petroleum-based brake fluids, a hydraulic brake hose assembly shall meet the constriction requirement of S5. Aftercyclesset the temperature of the environmental chamber to minus 40 degrees Fahrenheit minus 40 degrees Celsius.

Remove the tubing from the chamber and allow to warm at room temperature for one hour.

However, a particular hose assembly or appropriate part thereof need not meet further requirements after having met the constriction requirement S9. Utilize a cylinder with a diameter eight times the nominal outside diameter of the brake hose excluding armor.

Repeat the assembly and disassembly sequence three more times, and then reassemble the end fitting five total assembly steps. Small test cylinder, radius in inches millimeters 2. Immerse an air brake hose in a 50 percent zinc chloride aqueous solution at room temperature for hours.

Perform pressure cycles on the brake hose assembly. Without removing the hose from the test fixture, visually examine the hose for cracks without magnification, ignoring areas immediately adjacent to or within the area covered by the band clamps.

The extended plug gauge weight and spherical diameter specifications are as shown in Figure 4, but the handle portion of the gauge may be deleted and the gauge length may be greater than 3 inches. This is an approximate average radius. A hydraulic brake hose assembly or appropriate part thereof shall be capable of meeting any of the requirements set forth under this heading, when tested under the conditions of S13 and the applicable procedures of S6.

Title 12 – Banks and Banking. Brake hose testing is the most vital aspect of automotive manufacturing.

Title 17 – Commodity and Securities Exchanges. Visibly examine the interior of the hose for cracks without magnification. The collapse of the outside diameter of plastic air brake fmvsss shall not exceed twenty percent of the original outside diameter when bent degrees on a holding fixture to the unsupported bend radius specified in Table VIII and conditioned in air at degrees Fahrenheit 93 degrees Celsius for 24 hours.

Hose assemblies with end fittings that do not permit entry of the gauge e.

Condition the tubing in an air oven at degrees Fahrenheit degrees Celsius for 72 hours. Weight shall be measured to the nearest 0. A vacuum brake hose shall not show cracks visible under 7-power fvmss after exposure to ozone for 70 hours S If the plug gauge does not fully enter the hose up gmvss the handle of the gauge within three seconds, this constitutes failure of the constriction test.

Each air brake rmvss assembly made with end fittings that are attached by crimping or swaging, except those sold as part of a motor vehicle, shall be labeled by means of a band around the brake hose assembly as specified in this paragraph or, at the option of the manufacturer, by means of labeling as specified in S7.

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

All reusable end fittings are removed from the hose. Parts – Reserved. Title 16 – Commercial Practices. The inside of the container lower attachment point and upper attachment point of the machine have provisions to quickly attach a brake hose assembly for tensile testing.

Utilize test apparatus that is dynamically balanced and includes:.
