DIN EN 12580:2014-02 EN 12580:2013 (E) 4 Introduction Soil improvers and growing media are generally traded by volume as the weight of the product can be greatly affected by the moisture content. It is important for both consumers and traders to know the vo

22、lume of product being traded. Furthermore, for the cultivation of plants, it is the volume of the product, and not the weight, that is generally important. The volume is calculated from knowing the weight and bulk density of the product, the latter being determined from weighing a known reference vo

23、lume of product. For those materials traded by reference to its mass, this document recognises the effects the moisture content can have on the quantity declared. Therefore the principle is that for such transactions any weight should be accompanied by the moisture content so that the solid matter c

24、ontent can be calculated. As some soil improvers and growing media are compressible (and some may be presented in compressed blocks or bales), it is important that this aspect be addressed in the method of determining the bulk density. A suitably competent person should undertake this testing. Even

25、for materials traded by volume, the moisture content can have an effect as high moisture levels increase agglomerations, can reduce the ability to decompress or reconstitute materials, reduce their flow characteristics and give higher apparent bulk densities and lower volumes. The preparation and sa

26、mpling of all materials prior to quantity determination is covered in EN 12579. Quantity determination will be performed as soon as possible after preparation and sampling. DIN EN 12580:2014-02 EN 12580:2013 (E) 5 1 Scope This European Standard specifies methods for the determination of a quantity o

27、f soil improvers and growing media in bulk and in packages. This is a reference method, which is designed with an appropriate precision level so that it can be used to validate any quantity declaration made. This standard is applicable to material that is in solid form, reconstituted if necessary, b

28、ut not to blocks sold as such by dimension; for these, see EN 15761. This method is not applicable for material with more than 10 % (V/V) of particles greater than 60 mm in size; for these, see EN 15238. The requirements of this standard may differ from the national legal requirements for the declar

29、ation of the products concerned. Where there is no legal requirement to use this method, for example in quantity control of packaged product, then it is permissible for any other methods to be used so long as these other methods can be demonstrated to be comparable with this standard method in givin

30、g the same quantity with the same precision. Material which has become excessively wet and which cannot be easily broken down into a flowable material will not be suitable for the determination of quantity and may not give a representative result. However, because of the diverse nature and bulk dens

31、ity of these materials, it is not possible to quantify what is excessive. This standard is intended to be used by manufacturers, buyers and enforcement agencies in verifying claims made for these products. It is not intended that it should necessarily be used for the purpose of manufacturing control

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any ame

Note 2 to entry: Bulk density in this standard refers to the apparent density in air (based on conventional mass) and not the density in vacuum. 3.5 pac

37、kage container in which the goods are delivered and which remains with them after delivery Note 1 to entry: A package may be a loose-filled sack typically up to 100 l, a compressed block or bale and even a big bale, typically of 4 m3or more. 3.6 strike transparent sheet of flat material, normally gl

39、ivery in bulk or in packages, the quantity of material is determined and reported either by volume or by weight. The unit of measurement (weight or volume) used for the quantity declaration needs to comply with national regulations where they exist. 5.2 Where the quantity declared is by volume then

40、the material is weighed and then sampled and its bulk density is determined. From this information, the volume is then calculated. Clauses 6 to 11 of the standard apply. 5.3 Where the quantity declared is by weight then the moisture content is also determined so that the dry matter weight can be det

41、ermined and declared. Clauses 12 and 13 of the standard apply. NOTE The structure of the material can change with time and handling and this can affect the volume of the material. 6 Apparatus 6.1 Measure, rigid, 20 l 0,4 l with a height to diameter ratio between 0,9:1 and 1:1. The volume V1shall be

42、known to the nearest 10 ml at 20 C, with an uncertainty of measurement (k = 2) of no more than 50 ml. A standard 300 mm internal diameter pipe of height 283 mm with an end cap can be suitable. DIN EN 12580:2014-02 EN 12580:2013 (E) 7 The apparent weight of 1 l of water at 20 C is 997,15 g. Therefore

43、 no air buoyancy correction needs to be made. NOTE Information about the measurement and expression of uncertainty is given in the OIML Guide (G1) to the expression of uncertainty in measurement (sometimes referred to as GUM). 6.2 Collar, rigid, of the same diameter as the measuring cylinder (6.1) a

NOTE Wires crossing each oth

45、er at right angles form the mesh with the appropriately sized square holes. Ideally the fall controller should be separated from the measure to avoid jogging or vibrating material in the measure during the filling process.

46、ylinder (6.1) NOTE 1 For convenience and ease of use it is advisable to have 3 handles on the cylinder and 2 on the filling collar and the fall controllers. NOTE 2 For stability it is useful to have three short legs/feet on the base of the measuring cylinder. Figure 1 Diagrammatic representation of

For packaged material, the weighing instrument shall conform to Table 1 with class III tolerances as specified

48、 in EN 45501, unless more restrictive provisions exist in national regulations. For bulk material, the weighing instrument shall conform to class III of EN 45501. NOTE National legislation is likely to require that the equipment be verified before use, and so it will be marked with the CE mark and a
