19、 EN ISO 11127-5:2011ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a su
20、bject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (
21、IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committ
22、ees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be h

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 o
30、f free moisture present in non-metallic blast-cleaning abrasives. It is determined by measuring the mass lost on heating.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

35、 the oven (3.2) at (110 5) C for 15 min and allow it to cool to room temperature 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).5.3 DeterminationPlace the container with the test portion
36、in the oven (3.2), previously adjusted to (110 5) C, and leave for at 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
