25、rdization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to b

26、e represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards

27、 are drafted in accordance with the rules given in the ISO/IEC Directives, Part3.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

28、vote.Attention is drawn to the possibility that some of the elements of this International Standard may be the subject ofpatent rights.

31、d or solid. It also describes the apparatus used forthis process.NOTE Methods of sampling milk and milk products, including milk fats, are specified in ISO707.2 Terms and definitionsFor the purposes of this International Standard, the following terms and definitions apply.2.1 consignmentquantity of

32、fat delivered at one time and covered by a particular contract or shipping documentNOTE It may be composed of one or more lots or parts of lots.2.2 lotidentified quantity of fat, presumed to have uniform characteristics2.3 incrementquantity of fat taken at one time from one place in a lot2.4 bulk sa

33、mplequantity of fat obtained by combining the various increments from a lot in amounts proportional to the quantities theyrepresentNOTE The bulk sample should be representative of the lot and should take account of any contractual requirements.2.5 laboratory samplequantity of fat, obtained from the

34、bulk sample after suitable homogenization and reduction in size, which isrepresentative of the lot and intended for laboratory examination2.6 conventional mass per volume sample“litre weight in air” samplequantity of fat taken for the mass of fat to be calculated from the volume3 General principlesT

35、he object of sampling and of preparing samples is to obtain from a consignment (which may be in lots) amanageable quantity of the fat, the properties of which correspond as closely as possible to the properties of theconsignment sampled.BS EN ISO 5555:2002+A1:2014 EN ISO 5555:2002+A1:2014 (E)1 ISO :

37、, e.g. barrels, drums, cases, tins, bags and bottles.4 Requirements for apparatus4.1 GeneralFor a particular purpose, the choice of sampling instruments and their suitability depend on the skill of the sampler infollowing the recommended procedures.In all circumstances, it shall be borne in mind whe

38、ther the sample is intended for preliminary inspection, for analysis,or for the determination of conventional mass per volume (“litre weight in air”).4.2 MaterialsSampling instruments, ancillary apparatus and sample containers shall be made of materials which are chemicallyinert to the fat being sam

39、pled and they shall not catalyse chemical reactions.For sampling instruments, stainless steel is the most suitable material. Aluminium may be used only when the acidityis low but not for the storage of samples.Only plastics which meet the requirements of the first paragraph above, at the operating t

40、emperature conditions, maybe used; polyethylene terephthalate (PET) satisfying food contact requirements is recommended.Copper and copper alloys shall not be used nor any toxic material.WARNING If glass apparatus is used for a particular reason, great care shall be taken to avoid breakages.Under no

41、circumstances is glass permitted inside tanks containing oils and fats.4.3 Examples of types of sampling instruments4.3.1 GeneralMany forms and types of sampling instruments exist, and the instruments described in this International Standard areonly examples of those commonly used.The instruments ar

42、e all simple, robust and easily cleaned. They may be used for all the sampling operationsdescribed in this International Standard with all types of fats commonly found in commerce.Certain basic requirements are common to all sampling instruments; for example they shall be capable of taking arepresen

43、tative sample from a required level or area, and of preserving the integrity of the sample until it can betransferred to a sample container. Ease of cleaning, practical size and ability to withstand rough usage are otheressential characteristics.Alternative designs of instruments to those described

44、in this International Standard may be used, for example tomeet the needs of individual users.The instruments may be of various sizes according to the quantity of sample required and the accessibility of the fat.4.3.2 Sampling instrumentsThe following types may be used.BS EN ISO 5555:2002+A1:2014 EN

48、.5.2 The apparatus and sample containers shall be clean and dry prior to use.5.3 Sampling shall be carried out in such a manner as to protect the samples, the fat being sampled, the samplinginstruments and the sample containers from adventitious contamination with rain, dust, etc.5.4 All extraneous

49、material shall be removed from the outside of the sampling instruments before the instrumentsare emptied.5.5 If heating is necessary to facilitate sampling, it is important that fats are not overheated. It is recommended, inaccordance with usual practice, that the temperature of a bulk of fat in a storage tank should not be raised by morethan per day.The area of heating coils should be large in relat
