3.2.6 primary rein system—any natural or synthetic material or assembly designed for the purpose of controlling a horse while
riding or driving.
3.2.7 rein system section 1—the portion of the rein system defined as the section between the mid-point of the grip and distal
loop end of the rein system.
3.2.7.1 Discussion—
Rein system section 1 may or may not include some type of secondary rein system designed to permit the rein system to remain
functional should the primary rein system fail between the grip and connecting hardware or loop end of the rein.
3.2.8 rein system section 2—the portion of the rein system defined as the section between the mid-point of the grip of the right
rein leading away from loop end to the mid-point of the grip of the left rein.
3.2.8.1 Discussion—
Rein system section 2 may include a buckle assembly for connecting two single sections of rein. Rein system section 2 shall not
include a secondary rein system but may include connecting hardware.
3.2.9 secondary rein system—any natural or synthetic material or assembly designed to activate and function after a failure of
the primary rein system.
4. Significance and Use
4.1 All test procedures described in this specification are to be performed on new rein systems.
4.2 This specification is intended to measure the breaking force of the primary rein system and secondary rein system (if
applicable) as well as the breaking force of rein section 2 when loaded in a tensile testing machine.
4.3 This specification is not meant to be all inclusive since special circumstances may occur that dictate the use of
nonconforming procedures for evaluation of a rein system. These special circumstances and the requirements they establish cannot
be totally anticipated and therefore must be considered on an individual basis.
5. Apparatus
5.1 Testing Machines—Machines used for tension testing shall conform to the requirements of Practices E4. The loads used in
used in determining the breaking force of the reins shall be within the loading range of the tensile machine as defined in Practices
E4.
5.2 Gripping Devices:
5.2.1 General—Various types of gripping devices may be used to transmit the measured load applied by the testing machine
to the test specimens. To ensure axial tensile stress within the gage length, the axis of the test specimen should coincide with the
center line of the heads of the machine. Any departure from this requirement may introduce bending stresses that are not included
in the usual stress computation. It is essential that any gripping mechanism, whether it be a winch, wedge grip, or slip drum clamp,
not cause any damage or stress concentration in the test material that might influence the breaking strength. Failure away from the
area of the gripping mechanism is generally sufficient to demonstrate this.
5.2.2 Shackle and Eye Bolts—A shackle and eye-bolt loop assembly may be used at one end of the testing machine to attach
the loop end of the rein system to the testing machine. Where the loop end of the rein passes over the shackle or eye bolt, the
minimum effective diameter of the bearing surface must exceed 5 mm. The maximum load capacity of the shackle and eye bolt
must at least be greater than the 10 kN (2250 lb).
5.2.3 Tie Down Winch—A tie down winch assembly may be used at one of the testing machine to attach the strap or grip section
of the rein system to the testing machine. The tie down winch assembly shall have sufficient diameter that several revolutions of
strap section may be wrapped around the winch rod and held in place during tensile loading.
5.2.4 Wedge Grips—Testing machines usually are equipped with wedge grips. These wedge grips generally furnish a
satisfactory means of gripping long specimens of ductile material. If, however, for any reason, one grip of a pair advances farther
than the other as the grips tighten, an undesirable bending stress may be introduced. When liners are used behind the wedges, they
must be of the same thickness and their faces must be flat and parallel. For best results, the wedges should be supported over the
entire lengths of the heads of the testing machine. This requires that liners of several thicknesses be available to cover the range
of specimen thickness. For proper gripping, it is desirable that the entire length of the serrated face of each wedge be in contact
with the specimen. It is essential that the rein system is uniformly gripped when the load is applied.
5.2.5 Split Drum Clamps—Split drum type clamping systems that conform to Specification D6775 may be used to clamp the
rein systems in the testing machine. Ensure that the clamps are positioned such that they are facing opposite of each other in order
to ensure that the applied forces are acting through the rein system and no off-axis loading is occurring.
5.3 Recording Equipment—The recording equipment shall meet the following criteria:
F2842 − 11 (2017)
5.3.1 Force Transducer—A load cell or force transducer shall be mounted at the top or bottom of the support assembly in such
a manner that it shall be capable of reporting the magnitude of the axial tensile force applied to the rein system throughout the
entire duration of the testing sequence. The load cell shall be capable of measuring a force of at least 13.3 kN (3000 lb).
5.3.2 Force Recording—The force applied to the rein system shall be recorded using digital data processing that complies with
the requirements of SAE J211. The minimum sampling rate shall not be less than 100 Hz and the resolution of the data acquisition
system shall not be less than 12 bits (including sign).
5.3.3 Signal filtering—Analog or digital filtering of the force data channel shall comply with the requirements of SAE J211.
6. Performance Requirements
6.1 When the rein section 1 samples are tested according to the procedures described in Section 9, the maximum breaking force
for the primary rein system shall be greater than 2.22 kN (500 lb). If the primary rein section breaks at a maximum force of less
than 2.22 kN (500 lb), then the rein shall be considered to fail this performance requirement. Upon breakage of the primary rein
system, a secondary rein system shall be actuated and the maximum breaking force for the secondary rein system of rein section
1 shall be greater than 2.22 kN (500 lb) when tested according to the procedures described in Section 9.
6.2 When the rein section 2 samples are tested according to the procedures described in Section 9, the breaking force shall not
exceed 3.3 kN (750 lb).
7. Sampling and Test Schedule
7.1 A total of six complete rein systems as offered for sale shall be required for testing to this specification. Each rein shall be
prepared in accordance with the procedures in 9.1 and tested in accordance with the procedures described in 9.2.
7.2 Testing must begin within ten minutes after the t
