22、 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 held
23、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of an identical text or by endorsement, at the latest by January 1998, and conflicting national standards shall be withdrawn at the latest by January 1998. According to CEN/CENELEC Internal Regulat
24、ions, 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 the Uni

27、 a number of parts of ISO 11127 dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements on each are contained in the various parts of ISO 11126. The ISO 11126 and ISO 11127 series have been drafted as a coherent set of I
28、nternational Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A. This part of ISO 11127 specifies a method for the determination of the level of free moisture present in non-metallic blast-cleaning abrasives. It is determined by measuring
29、the mass lost on heating. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO 11127. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreem
30、ents based on this part of ISO 11127 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 11127-1:1993, Preparation of steel substrates before appli
31、cation of paints and related products Test methods for non-metallic blast-cleaning abrasives Part 1: Sampling. 3 Apparatus Ordinary laboratory apparatus and glassware, together with the following: 3.1 Container or tray, capable of withstanding the heat applied and of sufficient volume to allow the t
32、est portion to be spread in a thin layer. 3.2 Oven, capable of being maintained at a temperature of (110 5) C. 3.3 Balance, capable of weighing to an accuracy of 0,01 g. 3.4 Desiccator, containing a desiccant such as dried silica gel impregnated with cobalt chloride. 4 Sampling Take a representative
33、 sample of the product to be tested, as described in ISO 11127-1. Be sure to store the sample in a sealed container until required. 5 Procedure Carry out the determination in duplicate. 5.1 Test portion Dry the container (3.1) in the oven (3.2) at (110 5) C for 15 min and allow it to cool to room te
34、mperature in the desiccator (3.4). Weigh the container to the nearest 0,01 g. Weigh into the container, to the nearest 0,01 g, a test portion of approximately 100 g (m0). 5.2 Determination Place the container with the test portion in the oven (3.2), previously adjusted to (110 5) C, and leave for at
35、 least 1 h. Transfer the container to the desiccator and allow to cool to room temperature. Reweigh the container with the dried test portion to the nearest 0,01 g and determine the mass of the dried test portion (m1). 6 Expression of results Calculate the moisture content M, expressed as a percenta
36、ge by mass, using the equation: where If the duplicate determinations differ by more than 0,05 % (absolute), repeat the procedure described in clause 5. Calculate the mean of two valid determinations and report the result to the nearest 0,01 %. 7 Test report The test report shall contain at least th
37、e following information: a) all details necessary to identify the product tested, in accordance with the appropriate part of ISO 11126 (see Annex A), if applicable; b) a reference to this part of ISO 11127 (ISO 11127-5); c) the result of the test; d) any deviation from the test method specified; e)
38、the date of the test; f) the name of the person who carried out the test. m0is the mass, in grams, of the test portion before heating; m1is the mass, in grams, of the test portion after heating.
