The work
19、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen
20、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the
21、ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibi
22、lity that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

26、icted to dental amalgam reusable mixing-capsules; classification into two types has been deleted; labelling requirements have been updated. requirements for single-use capsules are now within the scope of ISO 20749:2017, these being: the requirement for surface contamination of the package and the c

29、ctrically-powered mixing machine, as described in ISO 7488 is used for mixing dental amalgam alloy powder with dental mercury. In addition, a removable mixing-capsule is used to contain the dental amalgam alloy and the dental mercury during the mixing process.NOTE Traditionally, the mixing machine f
30、or dental amalgam has been called an amalgamator. The latter is now a deprecated term.

44、e during mixing6.2.1 PrincipleThe loss of content from the mixing-capsule during mixing is determined by weighing the mixing-capsule initially and again after mixing. Repeating the measurement of loss of mass from the mixing-capsule and testing a number of mixing-capsules are required because the am
45、ount lost could vary from mix to mix and from capsule to capsule.6.2.2 Test sampleSelect five mixing-capsules at random. If the use of a pestle is recommended, select five of a type recommended for use with the mixing-capsule.If one of these mixing-capsules does not satisfy the requirement for the l
46、oss of mass from the mixing-capsule during mixing, a further five mixing-capsules from the same lot will be required.6.2.3 Apparatus6.2.3.1 Laboratory balance, with an accuracy and resolution of 0,1 mg.6.2.3.2 Periodontal probe, WHO type, ball ended (0,5 mm diameter).6.2.3.3 Brush having soft bristl
