ISO IEC 7811-1 pdf download.Identification cards — Recording technique — Part 1: Embossing
1 Scope
This document is one of a series of International Standards describing the parameters for identification cards as defined in the terms and definitions clause and the use of such cards for international interchange. This document specifies requirements for embossed characters on identification cards. The embossed characters are intended for transfer of data either by use of imprinters or by visual or machine reading. It takes into consideration both human and machine aspects and states minimum requirements. It is the purpose of this document to provide criteria to which cards shall perform. No consideration is given within this document 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 10373-1 specifies the test procedures used to check cards against the parameters specified in this document. NOTE 1 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. NOTE 2 Tactile Identifier Mark (TIM) defined by ISO/IEC 7811-9 can be located in the name and address area of this document. The layout of embossed characters in this area is not intended to interfere with TIM.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 7810 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — IEC Electropedia: available at http: //www .electropedia .org/ — ISO Online browsing platform: available at http: //www .iso .org/obp 3.1 embossing characters raised in relief from the front surface of the card 3.2 unused card card which has been embossed with all the characters required for its intended purpose but has not been issued 3.3 returned card embossed card after it has been issued to the card holder and returned for the purpose of testing 3.4 identification number number that identifies the card holder
4 Conformance
A prerequisite for conformance with this document is conformance with ISO/IEC 7810 for the ID-1 size card. An identification card is in conformance with this document if it meets all mandatory requirements specified herein. Default values apply if no others are specified.
5 Card characteristics
5.1 General Special attention shall be paid to the characteristics of the material affecting its suitability for this purpose, particularly in respect to its ability to resist crushing and collapsing of the embossed parts when operating in imprinters. Cards shall be made of PVC (polyvinyl chloride) and/or PVCA (vinyl chloride/vinyl acetate copolymer) or materials having equal or better performance such as polyesters, polyethylenes and polycarbonates. NOTE Refer to machine manufacturer instructions regarding card construction requirements for achieving embossed character relief heights in compliance with this document. At the time of publication there was no agreed on test method for verifying the suitability of card structures for embossing. See informative Annex C.5.2 Card warpage When lying convex side up on a flat rigid surface, the maximum distance from the flat surface to any non-embossed portion of the convex side of an embossed card immediately prior to issue shall not be greater than 2,5 mm (0.10 in) including the card thickness. NOTE The amount of card warpage depends on the card material and the embossing technique used. 5.3 Surface distortions No raised area shall exceed 0,51 mm (0.020 in) on the front of the card in the area A as shown in Figure 1.
