It applies to wide-mouth

21、 glass containers, designated for sterilization and other purposes, where a hermetic seal is required. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition

22、 indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid

23、International Standards. ISO7348:1991, Glass containers Manufacture Vocabulary. 3 Definitions For the purposes of this International Standard, the definitions given in ISO7348 and the following definition apply. 3.1 deviation from flatness of top sealing surface quantitative measure of a saddled fin

24、ish NOTE 1A saddled finish usually occurs after the container has been properly formed and before it leaves the annealing lehr. NOTE 2The deviation from flatness of the top sealing surface should not be confused with the “non-parallelism of finish with reference to container base” which is dealt wit

25、h in ISO9009:1991, Glass containers Height and non-parallelism of finish with reference to container base Test methods. 4 Principle 4.1 Quick check to determine whether the top sealing surface meets predetermined flatness requirements. 4.2 Measurement of the distance between the top sealing surface

26、and a flat plate pressed onto this surface. 5 Apparatus 5.1 Horizontal flat baseplate 5.2 Feeler gauges, in steps of0,05mm,i.e.0,05mm,0,1mm, etc. NOTE 3For rapid inspection, and especially for automatic checking, other apparatus exist. An example of such an apparatus works by measuring how good is t

27、he vacuum produced when the container is inverted on a standard rubber base and exhausted. 6 Sampling Sampling shall form the subject of agreement between the parties concerned. 7 Procedure 7.1 General Invert the container on the horizontal flat baseplate(5.1). If the container rocks, allow it to st

28、abilize before continuing with the determination. 7.2 Quick check to determine whether the top sealing surface meets predetermined flatness requirements 7.2.1 Select a feeler gauge(5.2) of the same thickness as the out-of-flatness deviation permitted. 7.2.2 Try to insert the feeler gauge in the gap,

29、 if present, between the baseplate and the top sealing surface throughout the circumference of the finish. During this operation the gauge shall lie flat on the baseplate and shall be moved smoothly on it. The feeler gauge is considered to be inserted when its head reaches over the inside edge of th

30、e finish, provided that during this operation the container under test does not rock or exhibit any other motion. 7.2.3 If the gauge cannot be inserted from any direction, the container is considered to meet the flatness requirement. 7.2.4 If the gauge can be inserted, repeat the procedure described

31、 in7.2.2 using the next thicker gauge. If this second gauge cannot be inserted, the container is considered to meet the flatness requirement. If this second gauge can be inserted, the container is considered as not meeting the flatness requirement. 7.3 Determination of deviation from flatness of top

32、 sealing surface 7.3.1 According to the case, select a feeler gauge of the same thickness as the out-of-flatness deviation permitted, or select the smallest gauge or the second smallest gauge (i.e.0,1mm). 7.3.2 Try to insert the feeler gauge selected, using the same procedure as described in7.2.2. 7

33、.3.3 Continue the determination using smaller or larger gauges as necessary. The determination is terminated when two gauges are identified which differ in thickness by not more than one step (i.e.0,05mm), the smaller one of which can be inserted and the larger one of which cannot. 8 Expression of r

34、esults 8.1 Quick check(7.2) If results by attributes are required, take as the result the number of containers which meet the flatness requirement.EN29885:1994 4 BSI 12-1999 8.2 Determination(7.3) For each container tested, take as the result the thickness, in millimetres, of the smaller of the two

35、gauges identified in7.3.3. 9 Test report The test report shall specify the following information: a) reference to this International Standard; b) reference to the test method(s) used (i.e.7.2 and/or7.3); c) the size of the sample and the type of container tested; d) manufacturing details; e) the typ
