Description / Abstract:
This International Standard specifies the requirements and test
methods for dental amalgam alloys that are suitable for the
preparation of dental amalgam, together with the requirements and
test methods for that dental amalgam and the requirements for
packaging and marking (including those for dental mercury).
It is applicable to dental amalgam alloys supplied in the form
of a free-flowing powder in bulk, or a powder compressed to form a
tablet, or a powder in a capsule (i.e. pre-capsulated).
With respect to dental mercury, the scope is limited solely to
dental mercury which is supplied precapsulated or in pre-dosed
sachets. Both are limited to a mass sufficient for one mix. The
mass of dental mercury in one capsule or sachet shall be sufficient
to produce a homogeneous plastic mix, appropriate for a small or
medium sized restoration in a single tooth. This International
Standard is not applicable to mercury supplied in masses greater
than this in a single primary container (i.e. dental mercury in
bulk). Dental mercury supplied in bulk volumes will not conform to
this International Standard.
This International Standard does not exclude the supply of
dental amalgam alloy or dental mercury separately.
This International Standard is not applicable to metallic
materials in which an alloy powder reacts with an alloy that is
liquid at ambient temperature to produce a solid metallic material
intended for dental restoration.
NOTE Dental mercury is at least 99,99 % pure,
and as such, it is a metallic element of high commercial purity,
and not an alloy
