3.1 SAMPLING OF BATTERIES
All tests shall he carried out on new battery samples. Samples shall he considered as new not later than—
(a) 60 days after the acid filling and formation date for filled and charged batteries and (b) 90 das after the manufacturer’s shipment date for dry -charged batteries.
3.2 PREPARATION OF BATTERIES BEFORE TEST—DEFINITION OF A FIJ LLV-CHARC ED BATTERV
All tests, except the cold cranking amps test of a dry or conserved charge battery. shall commence with fully-charged batteries.
To be considered fully-charged a battery shall:
(a) For vented batteries
Be charged at a voltage of 16 V ±0. I V for 24 h with the maximum current limited to
0.15 Cr1 (see Clause 1.3.1). The battery temperature shall be maintained in the range
25°C to 35°C. If necessary, an appropriate environmental control system shall be
used. e.g. a water bath.
(b) For valve-regulated batteries
Be charged at a voltage of 14.1 V ±0.1 V for 24 Ii. The battery temperature shall be maintained below 25°C. If necessary, an appropriate environmental control system shall be used. e.g. a water bath.
Any manufacturer’s recommendations concerning activation shall be followed.
3.4 MEASURING INSTRUMENTS
3.4.1 Electrical measuring instruments
The accuracy and type of the instruments to be used in the performance of the tests specified in this Standard shall be as follows:
(a) Voltmeter—Accuracy Class 0.5, resistance not less than 1000 Q/V, in accordance with IEC 6005 1-2, or digital voltmeters.
(b) Ammet—Moving coil, accuracy Class I, in accordance with IF.C 6005 1-2 or digital ammeters.
3.4.2 Temperature measurement
The thermometers used for measuring temperatures shall have an appropriate range, and the value of each scale division shall not be greater than 1°C. The accuracy of the calibration of the instruments shall be not less than 0.5°C.
3.4.3 Density liteasurement
The density of the electrolyte shall be measured with a hydrometer with a graduated scale. The valLie of each division of the scale shall be 5 kg/rn3. The accuracy of calibration shall be 5 kg/m3 or better.
4.3ACCEPTANCE TESTING
4.3.1Testing
Ten batteries shall be subject to the tests listed in Table 4.2.The tests shall be done in theorder shown in Table 4.2. If one battery fails any of the tests number 4,5,6,7 or 8 theeleventh battery (see Clause 4.2) may be substituted for the failed battery.
4.3.2 Criteria of acceptance
The batteries shall be deemed to comply with this Standard if all ten batteries pass the testslisted in Table 4.2.
When the eleventh battery is substituted for a failed battery and passes all of the tests listed for that battery, the batteries shall be deemed to comply with this Standard.
