TECHNICAL STANDARDS DOCUMENT
Number 206
Door Locks and Door Retention Components
This Technical Standards Document reproduces the content of Federal Motor
Vehicle Safety Standard No. 206, "Door Locks and Door Retention Components",
issued by the National Highway Traffic Safety Administration of the United
States Department of Transportation. The general requirements governing
Technical Standards Documents (TSD) are set out in section
12 of the Motor Vehicle Safety Act, which allows for
the use of a TSD to incorporate enactments by a foreign government. Because
the requirements of the Regulations may alter or override some provisions
or specify additional requirements, this Document should be read in conjunction
with the Motor Vehicle Safety Act and section
206 of the Motor Vehicle Safety Regulations. As
a guide, the subsection of the Regulations that alters or limits a TSD
provision is indicated in the margin by the number within parentheses.
Amendments to this TSD will be made from time to time to incorporate revisions
made to the reference document, and a Notice of Revision announcing an
amendment will be published in the Canada Gazette Part I. The revised
TSD will come into force six months after publication of the Notice.
Certain non-technical changes have been made to the U.S. standard by
the Department of Transport. These include the deletion of items that
do not apply under the Motor Vehicle Safety Act, minor changes
of an editorial nature, and the correction of a conversion error in S5.5.
Additions have been underlined, and provisions that do not apply
have been stroked-through. One section has been deleted
completely and marked "[CONTENT DELETED]".
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of superseded dates, and minor changes of an editorial nature.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 Dates
The original version of a TSD comes into effect on the date that the
regulation in which it is first incorporated by reference is published
in the Canada Gazette Part II. Subsequent revisions of a TSD come
into effect on the date of publication of the Notice of Revision in the
Canada Gazette Part I. The Effective Date is that of the publication
of the final amendment or the notice of revision in the Canada Gazette.
Compliance with the requirements of a newly issued TSD is not mandatory
until six months following the effective date, during which time it is
permissible to continue to comply with the requirements of the previous
Regulation or TSD. Manufacturers and importers must comply with the requirements
of a newly issued TSD as of the Mandatory Compliance Date.
