24、0 2 Foreword The text of the International Standard from Technical Committee ISO/TC 35, Paints and varnishes, of the International Organization for Standardization (ISO) has been taken over as a European Standard by Technical Committee CEN/TC 139, Paints and varnishes, the secretariat of which is he
25、ld by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 1997, and conflicting national standards shall be withdrawn at the latest by December 1997. According to CEN/CENELEC Internal Re
26、gulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and th

28、ealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-
29、cleaning abrasives. Information on all parts of both series is given in Annex A. This part of ISO 11125 specifies a test method for the determination of the apparent density of metallic blast-cleaning abrasives. The purpose of the test is to establish the soundness of the metallic abrasive. Signific
30、ant levels of internal shrinkage or hollow particles will reduce the apparent density. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11125. At the time of publication, the editions indicated were val
31、id. All standards are subject to revision, and parties to agreements based on this part of ISO 11125 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

33、f ISO 11125, the following definition applies. 3.1 apparent density the mass of a given volume of metallic abrasive, as determined by the pyknometer method described in this part of ISO 11125 4 Materials 4.1 Distilled or deionized water, of at least grade 3 purity as specified in ISO 3696. 5 Apparat
34、us Ordinary laboratory apparatus and glassware, together with the following: 5.1 Pyknometer, Gay-Lussac type, of capacity 50 ml, with a capillary stopper. 5.2 Balance, capable of weighing to an accuracy of 0,01 g. 6 Sampling Take a representative sample of the product to be tested, as described in I
35、SO 11125-1. 7 Procedure Carry out the determination in duplicate. 7.1 Weigh, using the balance (5.2), the clean, dry pyknometer (5.1) to an accuracy of 0,01 g (m1). 7.2 Add approximately 100 g of the test sample and reweigh (m2). 7.3 Add distilled or deionized water (4.1) to the pyknometer until it
36、is completely filled. Replace the stopper and gently shake the pyknometer to displace air adhering to the test portion. Remove the stopper, fill with water and then replace the stopper, forcing excess water out through the capillary tube. Carefully dry the outside of the pyknometer. Ensure there are
37、 no air bubbles present. Reweigh the pyknometer and its contents (m3). 7.4 Empty the pyknometer of water and test portion. Rinse several times to remove all traces of abrasive. Refill with distilled or deionized water, replace the stopper and ensure that there are no air bubbles present. Dry the out
38、side of the pyknometer and weigh (m4). NOTE 1Care should be taken that the pyknometer is handled as little as possible in order to prevent warming by hand. Pyknometer, test portion and water should as far as possible be at the same room temperature. Licensed Copy: sheffieldun sheffieldun, na, Sun No
