Door Locks and Door Retention Components

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 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or sections that do not apply under the Act or Regulations, the conversion of imperial to metric units, the deletion of superseded dates, and minor changes of an editorial nature.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 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.

Official Version of Technical Standards Documents

Technical Standards Documents may be consulted electronically in both HTML and Portable Document Format (PDF) on the Department of Transport's Web site. The PDF version is a replica of the TSD as published by the Department and is to be used for the purposes of legal interpretation and application.

S5.2.2 Door System. The test procedures for S4.2.2 are as follows:

S5.2.2.1 Tests are conducted using a full vehicle with the sliding door and its retention components.

S5.2.2.2 The test is conducted using two force application devices capable of applying the outward transverse forces specified in S5.2.2.4. The test setup is shown in Figure 10. The force application system shall include the following:

(a) Two force application plates.

(b) Two force application devices capable of applying the outward transverse load requirements for a minimum displacement of 300 mm.

(c) Two load cells of sufficient capacity to measure the applied loads specified in S5.2.2.4.

(d) Two linear displacement measurement devices required for measuring force application device displacement during the test.

(e) Equipment to measure for a 100-mm separation, as specified in S4.2.2.2(a), while respecting all relevant safety and health requirements.

S5.2.2.3 Test Setup

(a) Remove all interior trim and decorative components from the sliding door assembly.

(b) Remove seats and any interior components that may interfere with the mounting and operation of the test equipment and remove all pillar trim and any non-structural components that overlap the door and cause improper placement of the force application plates.

(c) Each force application device and associated support structure is rigidly fixed on a horizontal surface on the vehicle floor while applying the loads.

(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) (i) The force application plate is 150 mm in length, 50 mm in width, and at least 15 mm in thickness. The plate edges are rounded to a radius of 6 mm ± 1 mm.

(ii) The plates are rigidly fixed perpendicular to the force application devices to maintain the displacement of the force application plate in the transverse direction. The plates allow for longitudinal rotation with respect to the vehicle’s centreline axis. The plates do not allow for rotation in the vehicle’s transverse direction.

(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 such that the long edge of the plate is as close to the edge of the interior edge of the door as possible, but not such that the forward edge of the plate is more than 12.5 mm from the interior edge.

(g) For any tested door edge that contains more than one latch/striker, the following setup procedures are used:

(1) (i) The force application plate is 300 mm in length, 50 mm in width, and at least 15 mm in thickness. The plate edges are rounded to a radius of 6 mm ± 1 mm.

(ii) The plates are rigidly fixed perpendicular to the force application devices to maintain the displacement of the force application plate in the transverse direction. The plates allow for longitudinal rotation with respect to the vehicle’s centreline axis. The plates do not allow for rotation in the vehicle’s transverse direction.

(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 such that the long edge of the plate is as close to the edge of the interior edge of the door as possible, but not such that the forward edge of the plate is more than 12.5 mm from the interior edge.

(h) For any tested door edge that does not contain at least one latch/striker, the following setup procedures are used:

(1) (i) The force application plate is 300 mm in length, 50 mm in width, and at least 15 mm in thickness. The plate edges are rounded to a radius of 6 mm ± 1 mm.

(ii) The plates are rigidly fixed perpendicular to the force application devices to maintain the displacement of the force application plate in the transverse direction. The plates allow for longitudinal rotation with respect to the vehicle’s centreline axis. The plates do not allow for rotation in the vehicle’s transverse direction.

(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 such that the long edge of the plate is as close to the edge of the interior edge of the door as possible, but not such that the forward edge of the plate is more than 12.5 mm from the interior edge.

(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) Place the load application structure so that the force application plates are in contact with the interior of the sliding door.

(k) Apply a preload of 500 N to each actuator and “zero” the displacement measuring device.

S5.2.2.4 Test Procedure

(a) Move each force application device at any rate up to 2 000 N 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, hold the resulting load.

(d) Maintain each force application device load as specified in paragraph (c) and within 30 seconds measure the separation between the exterior edge of the door frame and the interior of the door along the perimeter of the door.
