ISO 9009:1991 download.Glass containers — Height and non-parallelism of finish with reference to container base — Test methods.
ISO 9009 specifies test methods for determining the height and the non-parallelism of finish with reference to the container base of glass containers.
2 NormatIve reference
The following standard contains provisions which, through reference in this text, constitute provisions of ISO 9009. At the time of publication, the edition iiidkuled was vatid All slandaids are subject to revision, and parties to agreements based on ISO 9009 are encouraged to investigate the possibility of applying the most recent edition of the standard Indicated below. Members of IEC and ISO maintain registers or currently valid International Standards.
ISO 7348:1991, Glass containers — Manufacture — Vocabulary.
3 DefInitions
For the purposes of ISO 9009, the definitions given in ISO 7348 and the following definitions ppIy.
3.1 (maxImum) height of a container: The distance between the highest point on the plane of the top surface of the finish and the standing surface. (See figure 1.)
3.2 minimum height of a container: The distance between the lowest point on the plane of the top surface of the finish and the standing surface, (Sf! figure 1.)
3.3 non-parallelIsm: The difference between the maximum and minimum heights of a container. (See figure 1.)
4 PrInciple
4.1 CheckIng of the height of a container using maximum and minimum GO/NO GO gauges or by using an appropriate measuring Instrument, Deter. minatlon of the (maximum) height.
4.2 Determination of the non-parallelism of finish.
S Apparatus
5.1 For checking the height
Various types or gauge exist. Examples are given In 5.1.1 and 5 1.2
5.1.1 HeIght gauge. consisting (or example of a baseplate with one or two vertical pillars and
a) a fixed horizontal cross-piece, In which case the distance between Pie baseplate and the cross- piece s equivalent to the thmension to be gauged, or
b) a fixed horizontal cross-piece with a step. In which case the distances between the baseplate and the two portions o( the cross-piece are equivalent to the maximum and minimum heights to be gauged (see, for example. figure 2), or
c) an adjustable horizontal cross-piece, which may be fixed at a distance from the baseplate equivalent to the distance to be gauged.
5.1.2 WIndow gauge, which combines minimum body diameter and maximum height.
5.2 For determination of height
Various types of apparatus exist, such as an engineering height vernier and a micrometer height gauge. Such apparatus shall have an accuracy or measurement of at least 0,1 mm.
5.3 For determination of non-parallelism The apparatus may be
a) that described In 51.1 C) together with feeler gauges in 0,1 mm steps, or
b) the apparatus described in 5 2.
For Quick qualitative determinations, a spirit level may be used.
6 Sampling
Sampling shall form the subject of agreement between the parties concerned.
7 Procedure
7.1 Height of container
7.1.1 QuIck check
Place the container on a metai baseplate. Set up a height gauge (5 11) (see. fnr example. figure 2) so that the minimum and maximum heights correspond to the height tolerance requirements to an accuracy of 0.1 mm.
Dctcrminc thoc contalncrs which slide under the highest portion of the gauge and which do not slide under the lowest portion of the gauge.
7.1.2 Determination of (maximum) height
Using an engineering height vernier or other suitable apparatus (5.2), measure the (maximum) height of the container to an accuracy of o,t mm.
7.2 Non-parallelIsm of finish with reference to container base
Place the container on a metal basepiate. Using an engineering height vernier or other suitable apparatus (5.2) measure, to an accuracy of 0.1 mm, the lowest point of the finish (i.e. the minimum height) and, if not already determined in 7.1.2, the highest point of the finish (i.e. the maximum height) (see figure 1).
8 ExpressIon of results
8.1 Height of container
8.1.1 Quick check (see 7.1.1)
II results by attributes are required, take as the result the number of containers which meet the height tolerance requirements,
8.1.2 (Maximum) height (see 7,12)
Take as the result the height, in millimetres, determined in 7,1.2.
8.2 Non-parallelism of finish with reference to container base
Take as the result the difference between the maximum and minimum heights. In millimetres, determined In 7.2.
9 Test report
The t.ct report shall specify the following lnformat ion:
a) reference to this International Standard;
b) reference to the test method(s) used (i.e. 7.1 and/or 7.2):
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.
