13、S0 61 : 1999 Foreword International Standard IS0 61 : 1976 Plastics - Determination of apparent density of moulding material that cannot be poured from a specified funnel, which was prepared by ISO/TC 61 Plastics of the International Organization for Standardization, has been adopted by Technical Co
14、mmittee CEN/TC 249 Plastics, the Secretariat of which is held by IBN, as a European Standard. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by December 1999 at the l
15、atest. In accordance with the CENKENELEC Internal Regulations, the national standards organizations of the follow- ing countries are bound to implement this European Standard: Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Ne
16、therlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. Endorsement notice The text of the International Standard IS0 61 : 1976 was approved by CEN as a European Standard without any modification.

17、ion Handling ServicesPage 3 EN IS0 61 : 1999 1 This International Standard specifies a method of determi- ning the apparent density, .e. the mass per unit of volume, of loose moulding material that cannot be poured from a funnel of specified design. NOTE - For a method of determining the apparent de
18、nsity of loose moulding material that can be poured from a specified funnel, see IS0 60. A knowledge of apparent density is of limited value in estimating the relative fluffiness or bulk of moulding materials, unless their densities in the moulded condition are approximately the same. SCOPE AND FIEL
19、D OF APPLICATION 2 APPARATUS 2.1 Balance, accurate to 0,l g. 2.2 Measuring cylinder, smoothly finished inside, which may be constructed of metal, of capacity 1 O00 * 20 ml and internal diameter 90 I2 mm. 2.3 Plunger, consisting of a hollow cylinder of mass 2300k 20g, closed at one end and having an
20、external diameter slightly smaller than the internal diameter of the measuring cylinder. The plunger may conveniently be weighted with lead shot. 3 PROCEDURE 3.1 Drop 60 f 0.2 g of loose moulding material, little by little, into the measuring cylinder (2.2) so that it is distrib- uted evenly with it
21、s surface as level as possible. Lower the plunger (2.3) slowly into the measuring cylinder until it is entirely supported by the material. After 1 min, measure the height of the material, with the plunger resting upon it, to the nearest 1 mm. A convenient method of measuring the height of the materi
22、al is, for example, by means of a suitable scale marked vertically on the outside surface of the plunger. 3.2 Make three determinations on the sample of moulding material under test. 4 EXPRESSION OF RESULTS The apparent density of the moulding material under test is given, in grams per millilitre (s
23、ee note) by the formula m Ah where m is the mass, in grams, of the material placed in the measuring cylinder (.e. 60); A is the internal cross-sectional area of the measuring cylinder, in square centimetres; h is the height of moulding material in the measuring cylinder, in centimetres. NOTE - Altho
24、ugh apparent density is calculated in grams per cubic centimetre, it is expressed here in grams per millilitre for the sake of uniformity with iSO60. No adjustment of the test result is required. Take as the result the arithmetic mean of the results of the three determinations. 5 TESTREPORT The test report shall include the following particulars : a) complete identification of the material tested; b) the individual results and the mean.
