The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject 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 (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 committees 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 held responsible for identifying any or all such patent rights.

Every National Committee has the right to be represented on the IDF Standing Committees carrying out the technical work. IDF collaborates with ISO and AOAC International in the development of standard methods of analysis and sampling for milk and milk products. Draft International Standards adopted by the Action Teams and Standing Committees are circulated to the National Committees for voting. Publication as an International Standard requires approval by at least 50% of IDF National Committees casting a vote.

1 Scope This International Standard specifies the reference method for the determination of the total solids content of cheese and processed cheese. NOTE This method may not be applicable to processed cheese preparations as defined in the FAO/WHO Code of Principles Standard A-8. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 total solids content of cheese mass fraction of substances determined by the procedure specified in this International Standard NOTE The total solids content is expressed as a percentage by mass. 3 Principle A weighed test portion mixed with sand is dried by heating it in a drying oven at 102 °C. The dried test portion is then weighed to determine the loss of mass. 4 Reagents Use only reagents of recognized analytical grade, and distilled or demineralized water or water of at least equivalent purity. 4.1 Dilute hydrochloric acid (HCl), with a mass fraction of 25 %. 4.2 Quartz sand or sea sand. 4.2.1 The sand shall pass through a woven wire cloth sieve with nominal size of aperture of 600 µm but is retained by a sieve with a nominal size of aperture of 150 µm. The sand shall comply with the suitability test given in 4.2.2. 4.2.2 Put approximately 20 g of sand in a flat-bottomed dish (5.4) with a stirring rod (5.5). Heat the opened dish with sand, stirring rod and its lid in the oven (5.3) set at 102 °C for at least 2 h. Close the dish and allow to cool in the desiccator (5.2) to the temperature of the balance room. Weigh the closed dish to the nearest 1 mg, recording the mass to four decimal places.

Heat the opened dish, stirring rod and its lid in the oven (5.3) set at 102 °C for at least 4 h. Close the dish and allow it to cool in the desiccator (5.2) to the temperature of the balance room. Weigh the closed dish to the nearest 1 mg, recording the mass to four decimal places. The difference between the two weighings shall not exceed 1,0 mg. 4.2.3 If this requiremen
