This British Standard is part 3 of a series of standard

10、s. It specifies requirements for flat-plate cells and batteries with pasted positive plates. It supersedes BS 6290-3:1986 which is withdrawn. BS 6290-1 has been withdrawn, having been superseded jointly by BS 6290-2:1999, BS 6290-3:1999, BS 6290-4:1997 and BS EN 60896-1:1992. BS 6290-2 specifies req

11、uirements for lead-acid high-performance Plante plate cells and batteries. BS 6290-4 specifies the criteria for classifying lead-acid valve-regulated cells and batteries.

12、safety and health aspects of the handling, installation, usage and maintenance of lead-acid stationary cells and batteries is given in BS 6133. Annexes designated normative are part of the body of the standard. A British Standard does not purport to include all the necessary provisions of a contract

The terminal pillars shall not carry any part of the weight of either plate group 4.6 Containers Containers shall be made of a plastics material, e.g. styrene acrylonitrile. 4.7 Cell

30、lids Cell lids shall be sealed to the container. Terminal pillars shall be sealed where they pass through the lid. NOTE The sealing should be designed to prevent corrosion of the pillar above the lid. Apart from the vent holes, the complete cell shall be sufficiently sealed to withstand an internal

31、pressure of 1 961 Pa (200 mmH 2 O). 4.8 Vent plugs Vent plugs shall allow no visible wetting of the cell lid when the cell is being overcharged at the 0.09C r3 rate at 208C ambient temperature, where C r3 is the rated capacity in amperes for a 3 h discharge time. 4.9 End springs or packing pieces En

32、d springs or packing pieces shall be provided to hold the plate groups in position. NOTE The end springs or packing pieces should be designed to hold the plate groups in position throughout the anticipated life of the cell. 5 Performance NOTE Operational recommendations relating to performance are g

33、iven in annex C. Information on recharge characteristics and operating characteristics is given in annexes D and E. 5.1 Capacity 5.1.1 The rated capacity shall be stated by the manufacturer in terms of a discharge time of 3 h, as detailed in BS EN 60896-1:1992, clause 6, i.e. C r3 . The fully charge

34、d electrolyte density that applies for the rated capacity shall be stated by the manufacturer. 5.1.2 When the actual capacity of a cell is measured as a laboratory type test in accordance with BS EN 60896-1:1992, clause 13, the cell shall achieve the rated value stated, C r3 , on the first discharge

35、. 5.1.3 When the actual capacity of a battery is measured as a site test in accordance with BS EN 60896-1:1992, clause 13, the battery shall achieve the rated value stated, C r3 , on the first discharge. No individual cell voltage shall be below 1.75 V after 2.5 h of discharge. NOTE The voltage of i

36、ndividual cells of a battery may fall below 1.80 V (subject to the requirement of 5.1.3). A cell whose voltage falls below 1.75 V after 2.5 h of discharge during site testing of a battery may be replaced and the test repeated. 5.1.4 If an additional test for capacity is required at a different disch

37、arge rate, the final voltages given in annex F shall apply. 5.2 Endurance When tested in accordance with BS EN 60896-1:1992, clause 15, the endurance, in charge/discharge cycles, shall be that stated by the manufacturer. 5.3 Constant-voltage float-charge operation When tested in accordance with BS E

38、N 60896-1:1992, clause 14, the cell, monobloc or battery shall meet the requirements specified in BS EN 60896-1:1992, 7.2. 5.4 Charge retention When tested in accordance with BS EN 60896-1:1992, clause 16, the charge retention shall be that stated by the manufacturer. 5.5 Short-circuit current and i

39、nternal resistance When tested in accordance with BS EN 60896-1:1992, clause 17, the short-circuit current and internal resistance shall be those stated by the manufacturer. BSI 02-2000 3 BS 6290-3:1999 5.6 Flammability of non-metallic parts When tested in accordance with method FV given in BS 6334:

40、1983, the flammability category in accordance with BS 6334:1983, 9.4 shall be that stated by the manufacturer. NOTE The principal non-metallic parts of a battery are the cell containers and lids. The flammability of the portion of the container in contact with electrolyte on its inner surface is red

41、uced considerably by the thermal capacity of the electrolyte. As a consequence, the parts of the containers above the electrolyte level, together with the lid and accessories, are those most vulnerable to fire damage. 6 Type tests NOTE Where individual cell voltages cannot be measured, e.g. in the c

42、ase of monobloc units, the cell voltage should be derived by dividing the voltage of the unit by the number of cells in the unit. Where a sample size is quoted in the test method, the value stated for cells applies to monobloc units. Type tests shall employ the test sequences recommended in BS EN 60

43、896-1:1992, clause 18. The accuracy of measuring instruments used in the tests shall conform to BS EN 60896-1:1992, clause 11. Cells and batteries shall be prepared for testing in accordance with BS EN 60896-1:1992, clause 12. 7 Identification marks Identification marks shall conform to BS EN 60896-

44、1:1992, as amended by Amendment No. 1, clause 19 to 22 (section six).BS 6290-3:1999 4 BSI 02-2000 Annexes Annex A (informative) Applications Electrical performance characteristics indicate that the pasted positive plate cell has a better energy density in ampere hours per cubic metre (Ah/m 3 ) than

45、the Plante cell at the 3 h rate of discharge. Whilst there is no reliable test to confirm the service endurance of the product, experience has shown that, under well maintained float-charge conditions, a product life of 10 years or more can be expected. However, product life depends upon plate desig

46、n, electrolyte density and operating parameters. The pasted positive plate cell used for stand-by purposes can be cycled, but its design is not appropriate to regular deep discharges. The pasted positive plate cell is particularly recommended for power systems where space for the battery is limited,

47、 and where a shorter service life, relative to the Plante cell, is acceptable. Typical applications are stand-by engine starting, uninterruptible power supplies and emergency lighting. NOTE When considering the size of a battery for a particular application, it should be recognized that service life

48、 is normally considered to have expired when the capacity falls to 0.8C r3 . The user should define the required level of performance at the end of service life and size the battery accordingly. Annex B (informative) Electromagnetic compatibility Rechargeable cells or batteries within the scope of t

49、his standard are not sensitive to normal electromagnetic disturbances, and therefore no immunity tests are required under the terms of Directive 89/336/EEC (EMC Directive) 1. Free-standing rechargeable cells or batteries electrically isolated from any associated electrical system are for all practical purposes electromagnetically inert, and therefore any requirement for conformity with Directive 89/336/EEC 1 in respect of electromagnetic emission is deemed to be satisfied. It should be noted that the electrical system in which rechargeable cells or batter
