Wide-mouth glass containers — Deviation from flatness of top sealing surface — Test methods to the formal vote The result of the formal vote was positive This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 1994, and conflicting national standards shall be withdrawn at the latest by October 1994 In accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany,

specifies two Sampling shall form the subject of agreement complementary test methods for the determination between the parties concerned of the deviation from flatness of the top sealing surface of wide-mouth glass containers Procedure It applies to wide-mouth glass containers, 7.1 General designated for sterilization and other purposes, where a hermetic seal is required Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard At the time of Invert the container on the horizontal flat baseplate (5.1) If the container rocks, allow it to stabilize before continuing with the determination 7.2 Quick check to determine whether the top sealing surface meets predetermined flatness requirements publication, the edition indicated was valid All 7.2.1 Select a feeler gauge ( 5.2) of the same standards are subject to revision, and parties to thickness as the out-of-flatness deviation permitted agreements based on this International Standard 7.2.2 Try to insert the feeler gauge in the gap, if are encouraged to investigate the possibility of present, between the baseplate and the top sealing applying the most recent edition of the standard surface throughout the circumference of the finish indicated below Members of IEC and ISO maintain During this operation the gauge shall lie flat on the registers of currently valid International Standards baseplate and shall be moved smoothly on it The ISO 7348:1991, Glass containers — Manufacture — feeler gauge is considered to be inserted when its Vocabulary head reaches over the inside edge of the finish, provided that during this operation the container Definitions For the purposes of this International Standard, the definitions given in ISO 7348 and the following definition apply 3.1 deviation from flatness of top sealing surface 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 in 7.2.2 using the next thicker gauge If this second gauge cannot be inserted, the quantitative measure of a saddled finish container is considered to meet the flatness NOTE requirement If this second gauge can be inserted, A saddled finish usually occurs after the container has been properly formed and before it leaves the annealing lehr NOTE The 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 with in ISO 9009:1991, Glass containers — Height and non-parallelism of finish with reference to container base — Test methods 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 the container is considered as not meeting the flatness requirement 7.3 Determination of deviation from flatness of top 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 0,1 mm) 7.3.2 Try to insert the feeler gauge selected, using the same procedure as described in 7.2.2 sealing surface and a flat plate pressed onto this 7.3.3 Continue the determination using smaller or surface larger gauges as necessary The determination is terminated when two gauges are identified which Apparatus 5.1 Horizontal flat baseplate differ in thickness by not more than one step (i.e 0,05 mm), the smaller one of which can be inserted and the larger one of which cannot 5.2 Feeler gauges, in steps of 0,05 mm, i.e 0,05 mm, 0,1 mm, etc Expression of results NOTE 8.1 Quick check (7.2) For rapid inspection, and especially for automatic checking, other apparatus exist An example of such an apparatus works by measuring how good is the vacuum produced If results by attributes are required, take as the when the container is inverted on a standard rubber base and result the number of containers which meet the exhausted © BSI 12-1999 flatness requirement EN 29885:1994 8.2 Determination (7.3) For each container tested, take as the result the thickness, in millimetres, of the smaller of the two gauges identified in 7.3.3 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/or 7.3); c) the size of the sample and the type of container tested; d) manufacturing details; e) the type of apparatus used; f) the results obtained; g) the tester’s name and signature, and date of test © BSI
