ISO IEC 7810 pdf download – Identification cards — Physical characteristics
5.1.2Card edges
Edge burrs normal to the card face shall not exceed 0,08 mm(0.003 in) above the card surface,
6Card construction
The card may be made of solid, laminated, or bonded materials, with or without inserts.
7 Card materials
The card shall be made of any material fulfilling the requirements of this International Standard.Card insertmaterial may be used.Card inserts are not, however, specied in this Intermational Standard and shall notinterfere with other requirements specified in this lnternational Standard.
WARNING— Some materials are sensitive to the effects of plasticizers which may be incorporated insome flexible plastic materials. ldentification cards kept in contact with such flexible plastics maydegrade the physical properties of the identification card.
8Card characteristics
The following general characteristics apply to identification cards. ID-000, IlD-2 and lD-3 size cards shall havethe same material properties as lD-1 size cards.
8.1 Bending stiffness
The bending stiffness of the lD-1 size card shall be such that deformations in normal use (bends not creases)can be removed by the recording or printing device without impairing the function of the card. The deformationwhich occurs when the card is subjected to the test load as described in ISO/EC 10373-1 shall be 35 mm(1.38 in) maximum and 13 mm (0.51 in) minimum. The card shall returm to within 1,5 mm (0.06 in) of itsoriginal flat condition within one minute after the load is removed.
8.2 Flammability
Resistance to flammabiity,if required，is specified in the International Standards dealing with the variousapplications of identification cards.
8.3Toxicity
The card shall present no toxic hazard in the course of normal use.
8.4Resistance to chemicals
The card shall meet the dimensional and warpage requirements, and there shall be no separation of cardcomponents after submersion in short term (1 minute) solutions and after submersion in the acid and alkalineartificial perspiration solutions, for 24 hours, as described in the referenced test method document.
8.5Card dimensional stability and warpage with temperature and humidity
After exposure to the following temperature and relative humidity:
temperature:
– 35 C to + 50c (- 31 °F to + 122F)
relative humidity:5 % to 95 %
The structural reliability shall remain in compliance for dimensions and warpage, as specified in Clause 5 and8.11 except for the ID-000 size card. Wider temperature ranges depending on the application are based onmutual agreement between the supplier and the card purchaser.
8.6Light
The card and its printed text shall resist deterioration from exposure to light encountered during normal use.
8.7Durability
Durability of the card is not established in this International Standard. lt is based on a mutual agreementbetween the card purchaser and the supplier.
8.8Peel strength
Component layers of material that form the card structure shall be bonded to the extent that any layer shallpossess a minimum peel strength of 0,35 Nmm (2 lbflin). if the overlay tears during the test,this signifies thatthe bond is stronger than the overlay,which is automatically deemed acceptable.
NOTE The issuer is warned that the card’s artwork design directly influences lamination bond strength. Certainprinting inks may prevent the card from meeting the delamination requirement The peel angle for this measurement is 90″,as described in iSO/IEC 10373-1.
8.9Adhesion or blocking
When finished cards are stacked together, the cards shall show no adverse effects such as:
a)delamination
b)discoloration or colour transferc)changes to surface finish
d)transfer of material from one card to anotherdeformation
The cards shall be easily separated by hand.
8.10 Opacity,ID-1 size card
All machine readable cards shall have an optical transmission density greater than 1,3 for the range of 450 nmto 950 nm, and greater than 1,1 for the range of 950 nm to 1 000 nm on all card areas except for area c andarea d as shown in Figure 2.Area c and area d as shown in Figure 2 may be optically transparent and do nothave a specified optical transmission density.
NOTE1 This characteristic is required for applications in which the presence of a card is detected by its attenuation oflight transmitted between a source and a sensor.
NOTE 2 There will be no opacity requirements for the range of 450 nm to 850 nm at the next revision of lSO/IEC 7810.Until that time , it is possible that alimited number of terminals may not be able to detect cards having lower than specifiedopacity in the 450 nm to 850 nm frequency range.
NOTE 3 Cards with area d transparent that are inserted with an incorect orientation may not be delteclted in someterminals.
NOTE4 The specified areas for opacity of machine readable cards has changed since the last edition of lSOIEC 7810.
