14、ction of the Packaging and Freight Containers Standards Committee, at the request of the Glass Manufacturers Federation and the National Association of Soft Drink Manufacturers. The control of capacity is a statutory requirement as stipulated in the Measuring Container Bottles (EEC Requirements) Reg
15、ulations 1977 (UK Statutory Instrument 1977 No. 932) which implements EEC Directive 75/107. The method of assessing compliance is given in full in the EEC Directive 75/107 on the approximation of the laws of Member states relating to bottles used as measuring containers. NOTEThe design and dimension
16、s of the neck finish shown in Figure 3 are based on glass container finish reference GF 301 prepared by the Glass Manufacturers Federation, 19 Portland Place, London W1N 4BH. Further Parts of this standard will cover other capacities of multi-trip bottles. This British Standard calls for the use of
17、substances and/or procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and in no way absolves the user from statutory obligations relating to health and safety at any stage of manufacture or use. In particular, attention is drawn t
18、o the tests for internal pressure resistance and thermal shock resistance. An amendment to this Part of this British Standard, which makes certain existing performance requirements more stringent and introduces new requirements for inspection and annealing, was the outcome of initial work on criteri
19、a concerning safety aspects of glass containers for carbonated soft drinks. This work is continuing and it is anticipated that certain clauses in this Part of this British Standard will be superseded by further British Standards concerning safety aspects once this work has been completed. NOTEAdditi
20、onal background information can be found in Packaging in glass by Moody, B. Revised ed. London: Hutchinson Benham, 1977. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance wit
21、h a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 10, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had am
22、endments incorporated. This will be indicated in the amendment table on the inside front cover.

35、shall be as shown in Figure 3. 8.2 Bore dimensions. Bore dimensions shall be measured using a gauge that enters the neck vertically. 8.3 Closure integrity. All sealing surfaces shall be essentially smooth and free from features that prevent adequate sealing. 9 Internal pressure resistance The minimu
36、m resistance to internal pressure of the bottles, shall be 16 bar sustained for 60 s, when tested in accordance with 13.2. NOTE1 bar = 105 Pa. 1 bar = 0.98 kg/cm2 1 bar = 14.5 lbf/in2 10 Verticality The maximum verticality (see 3.6) of the bottles, when tested in accordance with 13.3, shall be 3.3 m
37、m. 11 Thermal shock resistance The bottles shall resist, without breakage, the thermal shock imposed by a fall in temperature of 42 C when tested in accordance with 13.4. 12 Sampling 12.1 Dimensions, neck finish, internal pressure resistance, verticality, thermal shock resistance and annealing. An a
38、dequate sampling plan shall be adopted and detailed records of all test results shall be maintained. NOTEGuidance on sampling is given in Appendix B. 12.2 Sampling for capacity test. The number of bottles in the sample for the capacity test shall be as follows, depending on the method to be used to
39、determine compliance with UK Statutory Instrument No. 932 (see foreword). a) Standard deviation method: the sample size shall be 35 bottles which are representative of one hours production of the bottles. b) Mean range method: the sample size shall be 40 bottles which are representative of one hours
40、 production of the bottles. The sample of 40 bottles is subdivided into 8 subgroups of 5 bottles. NOTEUK Statutory Instrument No. 932 (see foreword) refers primarily to determination of capacity by the manufacturer or inspector. For capacity testing by the bottle user or other interested party, cons
41、ultation should be held with the bottle manufacturer in order to establish a scheme of sampling which complies with this subclause. 13 Test methods 13.1 Capacity test. The following test methods are essentially identical with the two official methods for determining compliance with UK Statutory Inst
42、rument No. 932 (see foreword): a) the standard deviation method; b) the mean range method. Either method may be used to determine compliance with 7.1. The gravimetric test method for determining the capacity at filling level shall be as follows for either method. Sampling shall be in accordance with
43、 12.2. Weigh each bottle empty. Fill each bottle to the filling level with water and weigh again. Determine the mass of water by subtraction, and express the capacity in millilitres, corrected to 20 C, using the temperature conversion given in Appendix A. In the standard deviation method the mean ca
44、pacity ( ) and estimated standard deviation (s) are calculated from 35 bottles which are representative of one hours production. The following inequalities shall be satisfied: s u 0.266 (Ts Ti) where Ts is the upper tolerance limit Ti is the lower tolerance limit as specified in 7.1 for each of the
45、bottles. In the mean range method the capacities of the 8 subgroups from one hours production are determined and the mean range () of the ranges of the 8 samples is calculated. The mean capacity of the 40 bottles is . The following inequalities shall be satisfied: x x1.57 s u Ts+ x1.57 s W Ti R x x0

The internal pressure is measured by the application of internal hy
47、draulic pressure to the bottle. Tap water is suitable for this purpose. 13.2.2 Apparatus. Several different types of equipment are available to increase the pressure either in steps or continuously. In order to achieve comparability between different pieces of equipment, the measured result is corre
48、cted to give the result that would have been obtained if the pressure had been increased in steps at intervals of 60 s as given in 13.2.4. 13.2.3 Procedure. Increase the pressure until the bottle breaks and measure the pressure. The rate of increase of pressure will be determined by the equipment us
49、ed; if the pressure is being increased manually, increase the pressure in increments of 2 bar every 30 s. NOTEIt is advisable to provide protection against flying glass which may be produced when the bottle breaks. 13.2.4 Correction of results. Most modern equipment will automatically correct to intervals of 60 s. If this facility is not available correct the result as shown below: Express the corrected result in bars. 13.3 Verticality test. Measure the verticality using apparatus incorporating a V-block and dial gauge. Care shall be taken wh
