EC Directive76/211, referred to in5.1.1, is implemented in the UnitedKingdom by the Weights and Measures (Packaged Goods) Regulations1979 (S
8、I1979/1613) as amended by the Weights and Measures (Packaged Goods) (Amendment) Regulations1980 (SI1980/1064). These Regulations were made under the Weights and Measures Act1979, which introduced into the UnitedKingdom the “average system” of metrological control. Copies of the above Regulations etc

17、eserved to all CEN membersEN76:1978 BSI 12-1999 2 Brief history This European Standard is based on the work of CEN/TC78 “Capacities of glass jars for preserved fruit, vegetables and similar products” and CEN/TC81 “Capacities of metal cans for fruit, vegetables and similar products”, the secretariats
18、 of which were held by DIN and IBN, respectively and later both by DIN. The proposal for this standard originated in a mandate of the Commission of the European Communities (CEC) dated28February1974. Representatives of the CEC from the department concerned have participated in the meetings of both t
19、echnical committees. During the meetings of CEN/TC78 representatives of the following countries participated: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Sweden, Switzerland, UnitedKingdom. In the preparation of its work CEN/TC81 had the opportunity to draw on t
20、he work already published by ISO/TC52. The following countries contributed to the work of CEN/TC81: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Sweden, Switzerland, UnitedKingdom. The Technical Committees prepared separate draft European Standards, i.e.prEN76 “P
21、ackages for certain pre-packed foodstuffs”, Part1: “Capacities, general considerations,” Part2: “Capacities of glass containers” and Part3: “Capacities of metal containers”. Subsequently, the CEC indicated that the work should come under a single scope and that they favoured a reduction in the numbe
22、r of capacities up to1700ml. Following a joint meeting of CEN/TC78 and CEN/TC81, the Conseil de Grance decided at its meeting in April1977 that a combined standard should be prepared having a scope which was aligned with that contained in the draft Directive published in the Official Journal of the
23、European Communities No. C193/3 dated1976-08-18. A first draft of a combined prEN76 was issued for final vote in June1977. Due to the unsuccessful result of the vote a subsequent joint meeting was held in February1978 to consider the comments submitted. This standard has been prepared in accordance
24、with the decisions of the CDG and incorporating the agreements made at the February1978 joint meeting. This European Standard was adopted by CEN on the strength of its acceptance by the following member countries: Austria, Denmark, Germany, Ireland, Italy, Portugal, Switzerland, UnitedKingdom. Conte

27、es) of vegetable products 1)(fruit, vegetables, tomatoes, potatoes) for human consumption. 1.2 Excluded from this standard are containers for pre-packaging jams, marmalades, chestnut paste, soups, sauces, baby foods, fruit and vegetable juices and all frozen and dried vegetable products. Also exclud
28、ed are vent-hole and dcollage metal containers. 2 Definitions 2.1 capacity of a glass container within the meaning of this standard is the brimful capacity determined according to6.1 2.2 capacity of a metal container within the meaning of this standard is the capacity of a closed container determine
29、d according to6.2 2.3 prepackage a prepackage within the meaning of this standard is the combination of a product and the individual package in which it is prepacked. A product is prepacked when it is placed in a package of whatever nature without the purchaser being present, and the quantity of pro
30、duct contained in the package has a predetermined value and cannot be altered without the package either being opened or undergoing a perceptible modification 2.4 tumbler a tumbler within the meaning of this standard is a means of packaging so designed that, when emptied, it can be used as a drinkin

34、Permissible errors 5.1 Glass containers 5.1.1 The brimful capacities of glass containers shall be checked for per cent defectives in accordance withsampling procedures and tables for inspection by variables for defective per cent with a2,5% acceptable quality level (AQL). This shall be carried out i
35、n accordance with EC Directive76/211 dated20January1976 concerning the approximation of the laws of the member States relating to the making up by weight or volume of certain prepackaged products. 5.1.2 To evaluate the results, the “standard deviation” or “mean range” methods may be applied. Metal c
36、ontainers. The maximum permissible error on the nominal capacity is the sum of the deviations of the mean capacities and the manufacturing tolerance. To comply with this standard,99,7% of the individual metal containers shall be within the limits of clause4. They result from the statistical distribu
37、tion between 3 (standard deviation) limits based on the declared capacity of the containers to which the tolerance applies. 6 Method of measurement 6.1 Glass containers. The brimful capacity is determined as follows. 6.1.1 Weigh the empty glass container. Nominal capacities, ml Upper and lower limit

One of the following methods should be used for determining the capacities of hermetically sealed metal containers. 6.2.1 Methods to be used for two-and three-piece containers with no
42、n-flexing sides and/or ends. 6.2.1.1 Apply one end to the body by the usual method (three-piece containers only). 6.2.1.2 Drill two holes3mm to4mm in diameter and about5mm apart in the loose end of the container and as close as possible to the countersink, from the inside surface outwards. 6.2.1.3 A
43、pply this end to the body by the usual method. 6.2.1.4 Weigh the empty container to the nearest gram. 6.2.1.5 Fill the container with water at a temperature of20 C 3)from a narrow water jet through one of the holes, with the container inclined at an angle to the vertical so that the holes are as hig
44、h as possible. 6.2.1.6 When water runs out of the second hole, ensure complete filling by closing the holes with the fingers, gently shaking the container and then completing the filling. 6.2.1.7 Remove any surplus water from the outside of the container. 6.2.1.8 Weigh the filled container to the ne
45、arest gram. 6.2.1.9 The difference between the weighings plus0,28% represents the capacity of the container in millilitres. 6.2.2 Method to be used for two- and three-piece containers when the use of method6.2.1 would result in distortion. 6.2.2.1 Apply one end to the body by the usual method (three
46、-piece containers only). 6.2.2.2 Drill two holes3mm to4mm in diameter and about5mm apart in the loose end of the container and as close as possible to the countersink, from the inside surface outwards. 6.2.2.3 Apply this end to the body by the usual method. 6.2.2.4 Weigh the empty container to the n
47、earest gram. 6.2.2.5 Fill the container with water at a temperature of20 C 3)from a narrow water jet through one of the holes, with the container inclined at an angle to the vertical so that the holes are as high as possible. 6.2.2.6 Place the container in a receptacle, filled with water, the holes
48、being at the highest point of the container. The water in the receptacle should be not more than10mm below the highest point of the container. 6.2.2.7 Fill the container completely using a pipette. 6.2.2.8 Close the holes with small pieces of adhesive tape. 6.2.2.9 Remove the container from the rece
49、ptacle. 6.2.2.10 Remove any surplus water from the outside of the container. 6.2.2.11 Weigh the filled container to the nearest gram. 6.2.2.12 The difference between the weighing plus0,28% represents the capacity of the container in millilitres. NOTEThe density correction of0,28ml for each100ml of capacity is based essentially on the temperature of the water which is weighed in the container, but also allows for the buoyancy of th
