13、dard has been prepared under the direction 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 Con
14、tainer Bottles (EEC Requirements) Regulations1977 (UK Statutory Instrument1977 No.932) which implements EEC Directive75/107. The method of assessing compliance is given in full in the EEC Directive75/107 on the approximation of the laws of Member states relating to bottles used as measuring containe
15、rs. NOTEThe design and dimensions of the neck finish shown inFigure 3 are based on glass container finish reference GF301 prepared by the Glass Manufacturers Federation,19 Portland Place, London W1N4BH. Further Parts of this standard will cover other capacities of multi-trip bottles. This British St
16、andard calls for the use of 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 part
17、icular, attention is drawn to 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 outcom
18、e of initial work on criteria 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 This work is continuing and it is anticipated that certain clauses in this Part of this British Standard will be superseded by further British Standards concerning safety aspects once this work ha
19、s been completed. NOTEAdditional 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
20、 application. Compliance with 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, pagesi andii, pages1 to10, an inside back cover and a back cover. This standard has been updated (see copyright d
21、ate) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS6119-1:1981 BSI 11-1999 1 1 Scope This Part of this British Standard specifies the design and dimensions, neck finish, capacity, internal pressure resistance, verticality, thermal

NOTEGuidance on sampling is given inAppendix B. 12.2 Sampling for capacity test. The number of bottles in the sample for the c
37、apacity test shall be as follows, depending on the method to be used to determine compliance with UK Statutory Instrument No.932 (seeforeword). a) Standard deviation method: the sample size shall be35 bottles which are representative of one hours production of the bottles. b) Mean range method: the
38、sample size shall be40 bottles which are representative of one hours production of the bottles. The sample of40 bottles is subdivided into8 subgroups of5 bottles. NOTEUK Statutory Instrument No.932 (see foreword) refers primarily to determination of capacity by the manufacturer or inspector. For cap
39、acity testing by the bottle user or other interested party, consultation 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 of
40、ficial methods for determining compliance with UK Statutory Instrument No.932 (see foreword): a) the standard deviation method; b) the mean range method. Either method may be used to determine compliance with7.1. The gravimetric test method for determining the capacity at filling level shall be as f
41、ollows for either method. Sampling shall be in accordance with12.2. 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 to20 C, using the temperature conversion given
42、 inAppendix A. In the standard deviation method the mean capacity () and estimated standard deviation (s) are calculated from35 bottles which are representative of one hours production. The following inequalities shall be satisfied: s u 0.266 (T s T i ) where T sis the upper tolerance limit T iis th
43、e lower tolerance limit as specified in7.1 for each of the bottles. In the mean range method the capacities of the8 subgroups from one hours production are determined and the mean range () of the ranges of the8 samples is calculated. The mean capacity of the40 bottles is . The following inequalities
44、 shall be satisfied: x x 1.57 s u T s + x 1.57 s W T i R x x 0.668R u T s + x 0.668R W T i R u 0.628T s T i ()BS6119-1:1981 BSI 11-1999 3 13.2 Internal pressure resistance test 13.2.1 Principle. The internal pressure is measured by the application of internal hydraulic pressure to the bottle. Tap wa
45、ter 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 corrected to give the result that would hav
46、e been obtained if the pressure had been increased in steps at intervals of60s as given in13.2.4. 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 used; if the pressure is being increased ma
47、nually, increase the pressure in increments of2bar every30s. 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 of60s. If this facility is not availab
48、le 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 while turning the bottle in the V-block to compensate for any pressure exerted by the dial gauge. Suc
49、h pressure exerted to overcome the dial gauge pressure shall be directed downward towards the V-block. The verticality is expressed as half the difference between the maximum and minimum readings of the dial gauge obtained during rotation of the bottle through360 . NOTEThe measurement obtained includes slight dimensional deviations that may occur in other parts of the bottle such as ring finish ovality, tilted finish, and rocky bottoms. No correction is made. 13.4 Thermal shock resistance test. Use two tanks filled with water. The water in
