    12、 direction of the Packaging and Freight Containers Standards Committee at the request of the Consumers Association. This British Standard replaces BS1925 “Capacity of glass milk bottles”, and BS2812 “Dimensions of glass milk bottles”Part1 “Bottles of the aluminium foil cap type”. These standards are

    13、 consequently now withdrawn and BS2812-2 “Bottles for sterilized milk” is also now withdrawn. The design of the bottle specified in this standard is commonly known as the “Pintie”. At the time of publication of this standard, different traditional tall bottle designs are still in use, although if th

    14、e present market trend continues, the Pintie will largely replace them. Details of the dimensions of the tall bottles may be obtained from the bottle manufacturer. The control of capacity is a statutory requirement as stipulated in the Measuring Container Bottles (EEC Requirements) Regulations1977 (

    15、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 approximation of the laws of member states relating to bottles used as measuring containers. NOTEThe design and dimensions of the neck finish ar

    16、e based on a glass container finish, reference GF124, prepared by the Glass Manufacturers Federation,19 Portland Place, London W1N4BH. 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.

    17、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, pages i and ii, pages1 to6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may

    18、have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS6106:1981 BSI 12-1999 1 1 Scope This British Standard specifies the design and dimensions, neck finish, capacity, verticality, thermal shock resistance, and markings for1pint(568ml) glass bott

    19、les for pasteurized milk, intended for multi-trip use as measuring containers. The bottle specified has a35 neck finish. Gauges for measuring dimensions, together with methods of test for capacity, verticality, and thermal shock resistance, are also specified. 2 References The title of the publicati

    20、on referred to in this standard is given on the inside back cover. 3 Definitions For the purposes of this British Standard the following definitions apply. 3.1 filling level the distance from the top of the neck finish to the centre of the meniscus measured on the centreline of the bottle, the bottl

    21、e resting on a horizontal surface 3.2 verticality the horizontal deviation of the centre of the bore entrance from a vertical line through the centre of the base, the bottle resting on a horizontal surface NOTEFor the method of measurement, see12.2. 4 Material The bottles shall be made from white fl

    22、int glass. 5 Bottle design The bottle designs shall be as shown in Figure 1. The glass distribution shall be as uniform as possible. The approximate glass mass shall be260g. 6 Dimensions 6.1 Requirement. The bottle dimensions shall be as shown in Figure 1. Sampling and acceptance levels shall be in

    23、accordance with11.1. 6.2 Checking. The toleranced body diameters (atthe shoulder and the base, seeFigure 1) shall be checked by, means of GO-NO GO gauges, using a ring gauge for the maximum diameter, and a gap gauge with a10mm wide anvil for the minimum diameter. The diameter of the neck finish shal

    24、l be checked using a Parnaby gauge, as shown in Figure 3, in which each engaging surface subtends an angle of90 . 7 Capacity 7.1 Capacity at filling level. The capacity at filling level of the bottles, when tested in accordance with12.1, shall be568 10ml. Sampling shall be in accordance with11.2. 7.

    25、2 Filling level. The filling level at20 C shall be15mm. 8 Neck finish 8.1 Design and dimensions. The design and dimensions of the neck finish shall be as shown in Figure 2. Sampling and acceptance levels shall be in accordance with11.1. 8.1.1 Bore dimensions. The minimum through bore shall be23.5mm.

    26、 Bore dimensions shall be measured using a gauge which enters the neck vertically. 8.1.2 Closure integity. All sealing surfaces shall be essentially smooth and free from features which prevent adequate sealing. 9 Verticality The maximum verticality (see3.2) of the bottles, when tested in accordance

    27、with12.2, shall be2.3mm. Sampling and acceptance levels shall be in accordance with11.1. 10 Thermal shock resistance Bottles shall resist, without breakage, the thermal shock imposed by a fall in temperature of35 C, when tested in accordance with12.3. Sampling and acceptance levels shall be in accor

    28、dance with11.1. 11 Sampling and acceptance levels 11.1 Dimensions, neck finish, verticality and thermal shock resistance. Dimensions, neck finish, verticality and thermal shock resistance of bottles shall be as detailed in Table 1. BS6106:1981 2 BSI 12-1999 Table 1 Sampling and acceptance levels for

    29、 dimensions, neck finish, verticality and thermal shock resistance 11.2 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 determine compliance with the UK Statutory Instrument. (See foreword.) Standard dev

    30、iation method. The sample size shall be35 bottles which are representative of one hours production of the bottles. Mean range method. The sample size shall be40bottles which are representative of one hours production of the bottles. The sample of40bottles shall be subdivided into eight subgroups of

    31、five bottles. NOTEThe UK Statutory Instrument (see foreword) refers primarily to determination of capacity by the manufacturer or inspector. For capacity testing by the bottle user or other interested party, consultation should be held with the bottle manufacturer in order to establish a scheme of s

    32、ampling which complies with the requirements of11.2. 12 Test methods 12.1 Capacity test. The following test methods are essentially identical with the two official methods for determining compliance with the UK Statutory Instrument (see foreword). a) The standard deviation method. b) The mean range

    33、method. Either method may be used to determine compliance with the requirements of7.1. The gravimetric test method for determining the capacity at filling level shall be as follows for either method. Sampling shall be in accordance with11.2. Weigh each bottle empty. Fill each bottle to the filling l

    34、evel 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 table given in Appendix A. In the standard deviation method the mean capacity() and estimated standard deviation (s) are calculated f

The following inequalities shall be satisfied. a) +1.57 su T s b) 1.57 sW T i c) su 0.266 (T s T i ) where T sis the upper tolerance limit T iis the lower tolerance limit as specified in7.1 In the mean range method the capacities of the

    36、eight subgroups from an hours production are determined and the mean range () of the ranges of the eight samples is calculated. The mean capacity of the40 bottles is . The following inequalities shall be satisfied. a) +0.668 u T s b) 0.668 W T i c) u 0.628 (T s T i ) 12.2 Verticality test. Measure t

    37、he verticality using an apparatus incorporating a V block and dial gauge, taking care while turning the bottle in the V block to compensate for any pressure exerted by the dial gauge. Direct this pressure downward towards the V block. Express the verticality as half the difference between the maximu

    38、m and minimum readings of the dial gauge obtained during rotation of the bottle through360 . NOTEThe measurement obtained includes slight dimensional deviations which may occur in other parts of the bottle, such as ring finish ovality, tilted finish, and rocky bottoms. No correction is made. 12.3 Th
