21、 the surrounding atmosphere. In order that tests may be made on a paper sack in a defined physical state, it is brought into equilibrium with an atmosphere of standardized temperature and relative humidity, and tested in that atmosphere. 1 Scope This part of ISO6599 specifies the conditioning atmosp

22、heres and the method for conditioning samples of intact, empty paper sacks before and during testing. If only conventional paper tests are to be carried out on the material of a sack, samples of this material shall be cut out and conditioned as specified in ISO187. 2 Field of application This part o

23、f ISO6599 applies to all types of empty paper sacks as specified in ISO6590-1. 3 References ISO187, Paper and board Conditioning of samples. ISO554, Standard atmospheres for conditioning and/or testing Specifications. ISO6590-1, Packaging Sacks Vocabulary and types Part1: Paper sacks 1) . 4 Principl

24、e Exposure of empty sacks to a conditioning atmosphere so that a state of temperature and moisture content equilibrium is reached between the sacks and this atmosphere. 5 Definitions For the purposes of this International Standard, the following definitions apply. 5.1 relative humidity (R.H.) the ra

25、tio of the absolute humidity of the air to the humidity of air saturated with water vapour at the same temperature and pressure NOTEThis ratio is usually expressed as a percentage. At ordinary atmospheric temperatures, this ratio is almost exactly equal to the ratio of the actual vapour pressure to

26、the saturation vapour pressure at the same (dry bulb) temperature. 5.2 conditioning the establishment of a temperature and moisture content equilibrium between empty sacks and an atmosphere of specified temperature and relative humidity 6 Conditioning atmospheres The Table indicates suitable conditi

27、oning atmospheres. Unless otherwise stated in the relevant specifications or test methods, or agreed between the interested parties, atmosphere23/50 shall be used. NOTEThe temperature and relative humidity conditions are those specified in ISO187 and ISO554. The tolerances quoted are the reduced or

28、close tolerances specified in ISO554. Table 7 Equipment 7.1 Room and measuring instrumentation The room in which conditioning is carried out shall be provided with automatic equipment for bringing the air to standard conditions of temperature and relative humidity and for so circulating it that thes

29、e conditions are uniformly maintained at all relevant points within it. It is recommended that a recording hygrometer, periodically checked by a standard method (for example with calibrated wet and dry bulb thermometers), be kept in the test space for checking purposes. 7.2 Determination of temperat

30、ure and relative humidity The relative humidity of the conditioning air shall be determined by a reliable method. Where a wet and dry bulb hygrometer is used, it shall be placed in an air current of the speed required by the tables used. This shall be not less than2m/s. 1) At present at the stage of

32、he bulbs dry, the difference in reading shall not exceed0,2 C. 8 Procedure The sacks shall be so suspended that the conditioning air circulates freely to all their outer surfaces and, in the case of open mouth sacks, to as much of the inner surface of the innermost ply as possible. 8.1 Minimum condi

33、tioning period for sacks without barrier plies Sacks without barrier plies shall be kept in the conditioning atmosphere for at least24h. 8.2 Minimum conditioning period for sacks with barrier plies Sacks with one or more barrier plies shall be kept in the conditioning atmosphere for at least7days. N

34、OTE 1ISO187 calls for preconditioning in an atmosphere of low relative humidity. Preconditioning is omitted here as with some sack constructions it may cause larger errors than those it reduces. NOTE 2Where the sack is to be filled with a product after conditioning, the product may change the moistu

35、re content of the paper and a further period for moisture equilibration may be needed; this should be not less than the minimum conditioning periods given in8.1 or8.2. 9 Test report The test report shall include the following particulars: a) a reference to this part of ISO6599; b) the conditioning a

36、tmosphere used(23/50,27/65 or20/65); c) the time taken to condition the sacks; d) any deviation from this part of ISO6599.BSEN26599-1:1993 BSI 12-1999 National annex NA (informative) Committees responsible The United Kingdom participation in the preparation of this European Standard was entrusted by
