ISO IEC 24789-2:2011 pdf – ldentification cards – Card service life – Part 2: Methods of evaluation.
– hole punch or equivalent;
magnetic stripe read test equipment with the following characteristics:
— ISO/IEC 10373-2 compliant;
— capable of reporting average signal amplitude (U,.) on middle third of Track 2 (see ISO!IEC 181 1-2.
ISO/IEC 7811-6 or ISO/IEC 7811-8).
Prepare the card by encoding on Track 2 with a reoordrng density of 8 ftpmm (200 ftpi), with a relative tolerance of ± 10%. at a recording current of I,,,,,. in accordance with ISO(IEC 7811.2. ISOIIEC 7811.6 or ISOIIEC 7811-8 and ISO1IEC 10373-2).
NOTE 1 If the magnetic stripe material is required lo comply y.jth any established standard, the compliance tests must be conducted and the results acceptable prior to this procedure.
Punch a hole in the card as shown In FIgure 2.
Measure the average signal amplitude in the read area shown in Figure 2.
Resurface the abrasive wheels for 50 cycles before testing begins and after every 100 cycles. Clean the cards and turntable using a dry soft cloth after the abrasive wheels are resurfaced. Avoid direct finger contact with the cards and abrasxin wheels. Complete the pi’ocedure for each card to the stopping powit before recommencing it with another card.
Mount the card on the turntable without any compliant pad. Add a filler card of the same thickness as the card on the specimen plate so that the abrasive wheels do not bounce when the procedure is in pmogress. Place the abrasive wheels (with the additional loads) on the card and the vacuum nozzle 6.4 mm (0.25 in) above the cards.
Preset the abraser for 50 cycles and start the abraser and vacuum. Ensure that the abrasive wheels do not bounce during the test.
Remove the card and clean the magnetic stripe thoroughly, using a dean soft cloth, to remove debris.
NOTE 2 ParllcLdar care should be taken to ensure that the stripe Is completely free from debris In order to avoid causing damage to the magnetic head used to measure the signal amplitude.
Re-measure average signal amplitude (UA) in the read area shown in Figure 2.
5.6 Wear and soil test
The purpose of this method is to evaluate the effect of abrasion of the entire face of the card.
NOTE Most appcopnaie for cards having surface features sudi as holograms, surface pnntlng, maelc stripes.
signature panels, etc.
— 160 pm or 180 pm sieve:
metal sieve (analytical sieve 63 pm. 0 200 mm. height 50 mm. according to ISO 3310-1) with cover. or pan bottom (0200 mm, height 50 mm) with cover
— vibrating device able to vibrate the metal s4eve or pan bottom along an axis perpendicular to the floor(s) of the sieve and approximately parallel to the local gravitational field, with an amplitude of 1,5 mm ± 0.2 mm (0.059 In i 0.008 in) at a frequency of 45 Hz to 60 Hz;
— 270 g (indicative mass) of polished solid glass pearls having a diameter of 7,0 mm ± 0,2 mm (0.275 in ± 0008 in);
soiling mixture ingredients as follows:
8,0 g ± 0.4 g peal, untreated. unfertilised;
— 2.0 g ± 0.1 g quartz sand61 40— 100 mesh ASTM;
0.5009 ± 0.0259 charcoal activated, grade: for analysis. eg Merck no 102186:
9.00 g ± 0.459 rac-Glycerol 1-monooleate, grade: technical, e.g. AldricWFtuka no. 49960,
200 pm +1- 20 pm thick PVC toil disk wIth an outer diameter 0 mm to 5 mm smaller than the inner diameter of the sieve or pan;
— miscellaneous items for cleaning glass pearls:
— any commercially available dishwastling detergent:
— a colander,
— double-sided thin adhesive tape having an adhesive that does not contaminate the card surface after removal of the tape;
— weighing device having a precision of 0,05g.
Prepare the soiling mixture as follows:
a) Giind reasonably dry peat dust (sphagnum) in an impact mill tor 5 mm.
b) Pass the ground peat dust through the sieve (160 pm or 180 pm).
NOTE I Choosing either of these sizes rather than the other will not affeci the results of the test.
