TECHNICAL STANDARDS DOCUMENT
Number 206, Revision 1
Door Locks and Door Retention Components
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 the corresponding Regulation contains additional requirements,
footnotes indicate the amending subsection number.
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of superseded dates, and minor changes of an editorial nature.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 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.1

until the required load has been achieved. Failure consists of a separation
of either the hinge. Record the maximum load achieved.
(b) Transverse Load. Attach the hinge system
to the mounting provision of the test fixture illustrated in figure 7.
Hinge attitude must simulate the vehicle position (door fully closed)
relative to the hinge centreline. For test purposes, the load is to be
applied equidistant between the linear centre of the engaged portions
of the hinge pin and through the centreline of the hinge pin in the transverse
vehicle direction. Apply the test load at a rate not to exceed 5 mm/min
until the required load has been achieved. Failure consists of a separation
of either the hinge. Record the maximum load achieved.
(c) Vertical Load. Attach the hinge system
to the mounting provision of the test fixture illustrated in figure 7.
Hinge attitude must simulate the vehicle position (door fully closed)
relative to the hinge centreline. For test purposes, the load is to be
applied through the centreline of the hinge pin in a direction
orthogonal to the longitudinal and transverse loads. Apply the test load
at a rate not to exceed 5 mm/min until the required load has been
achieved. Failure consists of a separation of either
the hinge. Record the maximum load achieved.

are not applicable and arrangement of the test fixture is altered so that
the test forces are applied to the complete hinge.

(d) Determine the forward and aft edges of the sliding door, or its
adjoining vehicle structure, that contains a latch/striker.
(e) Close the sliding door, ensuring that all door retention components
are fully engaged.
(f) For any tested door edge that contains one latch/striker, the
following setup procedures are used:
(1) The force application plate is 150 mm in length, 50 mm
in width, and at least 15 mm in thickness.
(2) Place the force application device and force application plate
against the door so that the applied force is perpendicular to the vertical
longitudinal plane that passes through the vehicle’s longitudinal centreline
and vertically centred on the door-mounted portion of the latch/striker.
(3) The force application plate is positioned as close to the edge
of the door as possible. It is not necessary for the force application
plate to be vertical.
(g) For any tested door edge that contains more than one latch/striker,
the following setup procedures are used:
(1) The force application plate is 300 mm in length, 50 mm
in width, and at least 15 mm in thickness.
(2) Place the force application device and force application plate
against the door so that the applied force is perpendicular to the vertical
longitudinal plane that passes through the vehicle’s longitudinal centreline
and vertically centred on a point midway between the outermost edges of
the latch/striker assemblies.
(3) The force application plate is positioned as close to the edge
of the door as possible. It is not necessary for the force application
plate to be vertical.
(h) For any tested door edge that does not contain at least one latch/striker,
the following setup procedures are used:
(1) The force application plate is 300 mm in length, 50 mm
in width, and at least 15 mm in thickness.
(2) Place the force application device and force application plate
against the door so that the applied force is perpendicular to the vertical
longitudinal plane that passes through the vehicle’s longitudinal centreline
and vertically centred on a point midway along the length of the door
edge, ensuring that the loading device avoids contact with the window
glazing.
(3) The force application plate is positioned as close to the edge
of the door as possible. It is not necessary for the force application
plate to be vertical.
(i) The door is unlocked. No extra fixtures or components may be welded
or affixed to the sliding door or any of its components.
(j) Attach any equipment used for measuring door separation that will
be used to determine separation levels during the test procedure.
(k) Place the load application structure so that the force application
plates are in contact with the interior of the sliding door.
S5.2.2.4 Test Procedure
(a) Move each force application device at a rate of 20 to 90 mm
per minute until a force of 9,000 N is achieved on each force application
device or until either force application device reaches a total displacement
of 300 mm.
(b) If one of the force application devices reaches the target force
of 9,000 N prior to the other, maintain the 9,000-N force with that
force application device until the second force application device reaches
the 9,000-N force.
(c) Once both force application devices have achieved 9,000 N
each, stop forward movement of the force application devices and hold
the resulting load for a minimum of 10 seconds.
(d) Maintain the force application device position of paragraph (c)
and measure the separation between the exterior edge of the door frame
and the interior of the door along the perimeter of the door.
