This International Standard gives the requirement for the permissible reduction in strength resulting from crevice corrosion of dental amalgam products that are within the scope of ISO 24234: Dentistry – Dental amalgam and ISO 20749: Dentistry – Pre-capsulated dental amalgam. It provides details of the test procedure for determining this.

This International Standard describes requirements for tooth-like colour representations made of ceramic materials used to determine the tooth colour in the patient’s mouth or to check the colour of dental prosthesis, which are referred to as shade guides (colour rings) in this standard. The coordinates of tooth colours in the colour space (colour coordinates) the specification of which is left to the manufacturers’ discretion as well as the colour deviations of ceramic and other masses or materials used in the manufacture of dental prosthesis do not fall into the scope of this standard. Resources for visualizing the colours of ceramic and other masses, e.g. mass shade guides and colour patterns for certain ceramic and other masses, do not fall into the scope of this International Standard. They can be manufactured from any materials and serve solely to illustrate the colour effect; they do not serve colour determination inside the mouth.

The purpose of this standard is to develop uniform nomenclature for the description of forensic dental data and define a standardized set of uniform terms to convey this information. The goal of the standard is not to define the extent of information collected, only to be certain that common terms are used in order to aid in an identifying human remains or a living amnesiac.

This document is one of a series of standards describing the characteristics for identification cards as defined in the definitions clause and the use of such cards for international interchange. This document specifies requirements for a high coercivity magnetic stripe (including any protective overlay) on an identification card and encoding technique. It takes into consideration both human and machine aspects and states minimum requirements. Coercivity influences many of the quantities specified in this document but is not itself specified. The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure. This is achieved with minimal probability of damage to other magnetic stripes by contact while retaining read compatibility with magnetic stripes as defined in ISO/IEC 7811-2. This document provides for a card capacity of approximately 10 times that of a card conforming to ISO/IEC 7811-6. The number of tracks has been increased to 6, each track being approximately half the width of tracks conforming to ISO/IEC 7811-6, located so that readers designed to read these high density tracks will also be able to read cards conforming to ISO/IEC 7811-2 and ISO/IEC 7811-6. Data is encoded in 8 bit bytes using the MFM encoding technique. Data framing is used to limit error propagation and error correction techniques further improve reliability of reading. It is the purpose of the ISO/IEC 7811 series of standards to provide criteria to which cards shall perform. No consideration is given within these standards to the amount of use, if any, experienced by the card prior to test. Failure to conform to specified criteria is negotiated between the involved parties. ISO/IEC 10373-2 specifies the test procedures used to check cards against the parameters specified in this document. NOTE Numeric values in the SI and/or Imperial measurement system in this document may have been rounded off and are consistent with, but not exactly equal to each other. Using either system is correct but intermixing or reconverting values can result in errors. The original design was made using the Imperial measurement system.
