Introduction
As defined by section
12 of the Motor Vehicle Safety Act, a Technical Standards Document
(TSD) is a document that reproduces an enactment of a foreign government
(e.g. a Federal Motor Vehicle Safety Standard issued by the U.S. National
Highway Traffic Safety Administration). According to the Act, the Motor
Vehicle Safety Regulations may alter or override some provisions
contained in a TSD or specify additional requirements; consequently, it
is advisable to read a TSD in conjunction with the Act and its counterpart
Regulation. As a guide, where modifications have been made, the corresponding
clause number is indicated in the margin of the TSD within parentheses.
TSDs are revised from time to time in order to incorporate amendments
made to the reference document, at which time a Notice of Revision is
published in the Canada Gazette, Part I. All TSDs are assigned
a revision number, with "Revision 0" designating the original version.
Identification of Changes
In order to facilitate the incorporation of a TSD, certain non-technical
changes may be made to the foreign enactment. These may include the deletion
of words, phrases, figures, or sections that do not apply under the Act
or Regulations, the conversion of imperial to metric units, the deletion
of superseded dates, and minor changes of an editorial nature. Additions
are underlined, and provisions that do not apply are stroked
through. Where an entire section has been deleted, it is replaced
by: “[CONTENT DELETED]”. Changes are also made where there
is a reporting requirement or reference in the foreign enactment that
does not apply in Canada. For example, the name and address of the U.S.
Department of Transportation are replaced by those of the Department of
Transport.
Effective Date and Mandatory Compliance Date
Compliance with the requirements of a TSD that is being introduced for
the first time is not mandatory until six months after publication in
the Canada Gazette, Part II, of the Regulations that incorporate
the TSD. In the case of a revision, compliance becomes mandatory six months
after publication of the Notice of revision in the Canada Gazette,
Part I, as long as the requirements of the previous version continue to
be met. Voluntary compliance is permitted as of the Effective Date of
the TSD.

plus 55 54kg of unsecured mass at each designated seating
position.
S7.2 Side moving barrier test conditions |
| |
(a) Vehicles manufactured before September 1, 2009 2004.
The side moving barrier crash test conditions are those specified in S8.2
of Standard No. 208 (49 CFR 571.208).
|
| |
(b) Vehicles manufactured on or after September 1, 2009 2004.
The side moving deformable barrier crash test conditions are those specified
in S6 and S7 of Standard No. 214 (49 CFR 571.214).
S7.3 Rear moving barrier test conditions |
| |
(a) Vehicles manufactured before September 1, 2009 2006.
The rear moving barrier test conditions are those specified in S8.2 of
Standard No. 208 (49 CFR 571.208), except for the positioning of the barrier
and the vehicle. The barrier and the test vehicle are positioned so that
at impact:
(1) The vehicle is at rest in its normal attitude;
(2) The barrier is travelling at 48 km/h with its face perpendicular
to the longitudinal centerline of the vehicle; and
(3) A vertical plane through the geometric center of the barrier impact
surface and perpendicular to that surface coincides with the longitudinal
centerline of the vehicle.
|
| |
(b) Vehicles manufactured on or after September 1, 2009 2006.
The rear moving deformable barrier is the same as that shown in Figure 2
of Standard No. 214 (49 CFR 571.214) and specified in 49 CFR,
Part 587, except as otherwise specified in paragraph S7.3(b). The
barrier and test vehicle are positioned so that at impact:
(1) The test vehicle is stationary;
(2) The deformable face of the barrier is mounted on the barrier 50 mm
(2 inches) lower than the height from the ground specified in Figure 2
of Standard No. 214 (49 CFR 571.214) (All dimensions from the
ground in Figure 2, Front View and Side View, should be reduced
by 50 mm [2 inches].);
(3) The barrier is travelling at 80 km/h ± 1.0 km/h; and
(4) The barrier impacts the test vehicle with the longitudinal centerline
of the vehicle parallel to the line of travel and perpendicular to the
barrier face within a tolerance of ± 5 degrees. The test vehicle
and barrier face are aligned so that the barrier strikes the rear of the
vehicle with 70 percent overlap toward either side of the vehicle. So
aligned, the barrier face fully engages one-half of the rear of the vehicle
and partially engages the other half. At impact, the vehicle’s longitudinal
centerline is located inboard of either of the side edges of the barrier
by a distance equal to 20 percent of the vehicle’s width ±
50 mm (see Figure 3). The vehicle’s width is the maximum
dimension measured across the widest part of the vehicle, including bumpers
and molding, but excluding such components as exterior mirrors, flexible
mud flaps, marker lamps, and dual rear-wheel configurations.

S7.4 Static rollover
test conditions
The vehicle is rotated about its longitudinal axis, with the axis kept
horizontal, to each successive increment of 90°, 180°, and 270° at a uniform
rate, with 90° of rotation taking place in any time interval from 1 to
3 minutes. After reaching each 90° increment, the vehicle is held
in that position for 5 minutes.
S7.5 Moving contoured barrier test conditions
The following conditions apply to the moving contoured barrier crash
test.
S7.5.1 The moving contoured barrier, which is mounted on
a carriage as specified in Figure 1, is of rigid construction, symmetrical
about a vertical longitudinal plane. The contoured impact surface, which
is 629 mm high and 1,981 mm wide, conforms to the dimensions shown in
Figure 2 and is attached to the carriage as shown in that figure. The
ground clearance to the lower edge of the impact surface is 133 mm ±
13 mm. The wheelbase is 3,048 mm ± 50 mm.
S7.5.2 The moving contoured barrier, including the impact surface,
supporting structure, and carriage, has a mass of 1,814 kg ± 23 kg
with the mass distributed so that 408 kg ± 11 kg is at
each rear wheel and 499 kg ± 11 kg is at each front wheel.
The center of gravity is located 1,372 mm ± 38 mm rearward
of the front wheel axis, in the vertical longitudinal plane of symmetry,
401 mm ± 13 mm above the ground.
S7.5.3 The moving contoured barrier has a solid nonsteerable
front axle and fixed rear axle attached directly to the frame rails with
no spring or other type of suspension system on any wheel. (The moving
barrier assembly is equipped with a braking device capable of stopping
its motion.)
S7.5.4 The concrete surface upon which the vehicle is tested is
level, rigid, and of uniform construction, with a skid number of 75
when measured in accordance with American Society of Testing and Materials
Method E: 274‑65T at 64 km/h, omitting water delivery
as specified in paragraph 7.1 of that method.
S7.5.5 The barrier assembly is released from the guidance mechanism
immediately prior to impact with the vehicle.
