21、test location 27 + 1 m1 65 i 2 - 5 Definitions The physical properties of paper are affected materially by its moisture content, which is dependent on the humidity and temperature of the surrounding atmosphere. In order that tests may be made on a paper sack in a defined physical state, it is brough
22、t into equilibrium with an atmsphere of standardized temperature and relative humidity, and tested in that at- mosp here. 1 Scope This part of IS0 6599 specifies the conditioning atmospheres and the method for conditioning samples of intact, empty paper sacks before and during testing. If only conve
23、ntional 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 IS0 187. 2 Field of application This part of IS0 6599 applies to all types of empty paper sacks as specified in IS0 659011. 3 References IS0 187, Paper and b

IS0 669011, Packaging - Sacks - Vocabutary and types - Part 1 : Paper sacks. 1) 4 Principle Exposure of empty sacks to a conditioning atmosphere so that a state of temperature and moistur
25、e content equilibrium is reached between the sacks and this atmosphere. For the purposes of this International Standard, the following definitions apply. 5.1 relative humidity (R.H.) : The ratio of the absolute humidity of the air to the humidity of air saturated with water vapour at the same temper
26、ature and pressure. NOTE - This 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 the saturation vapour pressure at the same (dry bulb) temperature. 5.2 conditioning : The establishment o
27、f a temperature and moisture content equilibrium between empty sacks and an at- mosphere of specified temperature and relative humidity. 6 Conditioning atmospheres The table indicates suitable conditioning atmospheres. Unless otherwise stated in the relevant specifications or test methods, or agreed
28、 between the interested parties, at- mosphere 23/50 shall be used. NOTE - The temperature and relative humidity conditions are those specified in IS0 187 and IS0 554. The tolerances quoted are the reduced or close tolerances specified in IS0 554. Table Relative Remarks I l l 23/50 I 23il I 50 t 2 I
29、Preferred atmosphere 1) At present at the stage of draft Page 4 EN 26 599-1 : 1992 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 con- ditions of temperature and relative hum
30、idity and for 50 cir- culating it that these conditions are uniformly maintained at all relevant points within it. It is recommended that a recording hygrometer, periodically checked by a standard method (for ex- ample with calibrated wet and dry bulb thermometers), be kept in the test space for che
31、cking purposes. 7.2 Determination of temperature 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
32、 less than 2 m/s. When the thermometers of the hygrometer are at the same temperature, with the bulbs dry, the difference in reading shall not exceed 0,2 OC. 8 Procedure The sacks shall be so suspended that the conditioning air cir- culates freely to all their outer surfaces and, in the case of open
33、 mouth sacks, to as much of the inner surface of the innermost ply as possible. 8.1 without barrier plies Sacks without barrier plies shall be kept in the conditioning at- mosphere for at least 24 h. Minimum conditioning period for sacks 8.2 Minimum conditioning period for sacks with barrier plies S
34、acks with one or more barrier plies shall be kept in the condi- tioning atmosphere for at least 7 days. NOTES 1 IS0 187 calls for preconditioning in an atmosphere of low relative humidity. Preconditioning is omitted here as with some sack construc- tions it may cause larger errors than those it redu
35、ces. 2 Where the sack is to be filled with a product after conditioning, the product may change the moisture 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 in 8.1 or 8.2. 9 Test report The test repon shall include the following particulars : a) a reference to this part of IS0 6599; b) the conditioning atmosphere used (23J50, 27/65 or 20/65); c) the time taken to condition the sacks; d) any deviation from this part of IS0 6599.
