32、r liquid or solid. It also describes the apparatus used forthis process.NOTE Methods of sampling milk and milk products, including milk fats, are specified in ISO 707.2 Terms and definitionsFor the purposes of this International Standard, the following terms and definitions apply.2.1 consignmentquan

33、tity of 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

34、 bulk samplequantity 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 f

35、rom the 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 pri

36、nciplesThe 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.EN ISO 5555:2001 + A1:2014 (E) 4 DIN EN ISO 5555:2014-1

37、0 The methods of taking samples described below are intended for the guidance of experts and may be used fora) consignments in bulk, e.g. in land tanks, ships tanks, tank wagons, tank cars and tank containers, andb) consignments consisting of a number of packages, e.g. barrels, drums, cases, tins, b

38、ags 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 whether the sample is intended for preli

39、minary 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 sampled and they shall not catalyse chem

40、ical 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 temperature conditions, maybe used; po

41、lyethylene 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 circumstances is glass permitted insi

42、de 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 are all simple, robust and easily clean

43、ed. 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 arepresentative sample from a required level o

44、r 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 in this International Standard may be

45、 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.EN ISO 5555:2001 + A1:2014 (E) 5 DIN EN ISO 5555:2014-10 a) Simple w
