20、s a gravimetric method for determining the capacity of glass containers and their compliance with specification limits. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated

21、references, the latest edition of the referenced document (including any amendments) applies. ISO 7348:1992, Glass containers Manufacture Vocabulary. 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 7348:1992 apply. 4 Principle Calculation of the capa

22、city of a glass container from the mass of the water filling the container, adjusted by a factor for density of the water at a given temperature. 5 Sampling The test shall be performed on a predetermined number of containers which shall be representative of the consignment. 6 Apparatus 6.1 General p

23、urpose calibrated thermometer, with a scale range graduated in increments of at least 1 C. 6.2 Balance, with an accuracy as specified in Table 1. 6.3 Strike plate, for brimful determination of wide-mouth containers. 6.4 Depth gauge, for filling level determination. EN ISO 8106:2004 (E) 5 Table 1 Acc

24、uracy limits for balance Capacity (ml) Accuracy limits for the measurement equipment for the gravimetric determination of container capacities (g) Up to 10 0,1 Over 10 Up to 250 0,25 Over 250 Up to 1000 0,5 Over 1000 Up to 5000 1,25 Over 5000 5 7 Procedure 7.1 The reference test temperature is 20 C.

25、 A volume correction factor is applied depending on the temperature at which the test is carried out. 7.2 Using the general purpose calibrated thermometer (6.1), measure the temperature of the water and ensure that it remains within 1 C of the measured value throughout the test. 7.3 Using the balanc

26、e (6.2), weigh the dry, empty container which shall be at ambient temperature and ensure that it remains within 1 C of the measured value throughout the test. 7.4 The container shall be filled on a flat, horizontal surface. The outer surface of the container shall be kept dry throughout the test pro

27、cedure. 7.5 For the determination of brimful capacity fill to just less than, but as near as possible to, the brimful level. The container shall then be topped up with water until the top of the meniscus is level with the top of the rim. For wide mouth containers, place the strike plate across the m

28、outh of the container and top up with water until the meniscus just touches the strike plate. No air bubble shall be trapped underneath the strike plate. 7.6 For the determination of the filling level capacity fill to just less than the fill level. The depth gauge (6.4), adjusted to the specified le

29、vel, shall be inserted centrally and vertically into the neck of the container. The container shall then be filled with water until the centre of the meniscus just touches the tip of the gauge. 7.7 The filled container shall be weighed to the accuracy specified in Table 1. 8 Expression of results 8.

30、1 Calculation of capacity The capacity of the container shall be calculated from the difference between the value of the mass of the filled container and that of the empty container, and shall be expressed as a volume in millilitres. EN ISO 8106:2004 (E) 6 8.2 Calculation of actual capacity The actu

31、al capacity of the container, expressed in millilitres, shall be calculated from the equation Actual capacity = m x VCF where m is the measured mass of water, in grams; VCF is the volume correction factor for water at the test temperature in ml/g. Table 2 gives the volume correction factors for the

32、temperature within the permitted range for distilled water. However in practice non-distilled tap water is mainly used for capacity measurements. lt is therefore necessary to apply additional correction factors, such as for the density of the tap water, appropriate to the location where the measurem

33、ent is carried out. NOTE See Directive 75/107/EEC for the requirement to correct all tests to 20C.
