11、ew. BSISO6576:2004 iii Foreword ISO (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
12、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 Commissi
13、on (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 c
14、ommittees 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 n
15、ot be held responsible for identifying any or all such patent rights. ISO 6576 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 7, Spices and condiments. This second edition cancels and replaces the first edition (ISO 6576:1984), of which it constitutes a minor revision.

The laurel leaf is oblong, tough, lanceolate, more or less undulated at the edges, pointed or obtuse at the tip (depending on the origin) with a short petiole. It is green on
21、the surface, the underneath being lighter in colour, sometimes approaching yellow. Its length varies from to and its width from to at the widest point of the leaf (depending on the origin). When it is dry, the leaf is soft, shiny on the surface and dull underneath. It has veins which are visible on
22、the surface and prominent on the underneath. A filament of small veins is clearly visible. (See Figure 1.) 1) Commonly known as “bay laurel” or “bay-leaves” and should not be confused with Pimenta racemosa (Miller) J.W.

If the magnification exceeds , this fact shall be stated in the test report. 3.4 Extraneous matter For the purposes of this International Standard, extraneous matter is considered to be a) all matter which does not constitute the laurel le
26、af, in particular stems, and b) all other extraneous animal, vegetal and mineral matter. The total extraneous matter content, when determined by the method specified in ISO 927, shall not exceed(by mass). 3.5 Classification Laurel may be classified according to its country of production and the dime
27、nsions of its leaves. The main producing countries are listed in Annex B. 3.6 Chemical requirements Laurel shall comply with the requirements given in Table 1. 4 Sampling Sample consignments of laurel in accordance with ISO 948. Prepare a ground sample for analysis in accordance with ISO 2825, such
28、that the whole of the product passes through a sieve of aperture size .
