27、2006, Uncontrolled Copy, (c) BSI EN ISO 11127-4:1997 BSI 04-19993 1 Scope This is one of 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 o
28、f ISO 11126. The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International 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 of assessing whether a non-metallic blast-cl
29、eaning abrasive has a minimum hardness of 6 on Mohs scale. NOTE 1The test described in this part of ISO 11127 is a pass/fail test and is not a method for the accurate determination of hardness. 2 Normative reference The following standard contains provisions which, through reference in this text, co
30、nstitute 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 agreements based on this part of ISO 11127 are encouraged to investigate the possibility of applying the most recent edition of the standa
31、rd indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

33、resent, select a few grains of each. 5.2 Place the selected grains between two glass microscope slides (3.2) and, whilst applying pressure, slowly move one slide over the other with a reciprocating motion for 10 s. Examine the glass surfaces and, if scratched, the material shall be considered as hav
34、ing a minimum hardness of 6 on Mohs scale. 6 Test report The test report shall contain at least the 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 11
