本標(biāo)準(zhǔn)規(guī)定了谷物水分電子測量儀的基本技術(shù)要求、試驗方法、檢驗規(guī)則和標(biāo)志、包裝、運輸、貯存等要求。 本標(biāo)準(zhǔn)適用于通過電量來測量谷物水分含量的電子測量儀器。對于多用儀器(如谷物水分、溫度電子測量儀)中的水分測量部分也應(yīng)符合本標(biāo)準(zhǔn)的規(guī)定。
This International Standard specifies requirements for the dynamic or static sampling, by manual or mechanical means, of cereals and cereal products, for assessment of their quality and condition
Specifies a routine reference method for the determination of the moisture content of cereals and cereal products
This document specifies a method that uses an alveograph to determine the rheological properties of different types of dough at adapted hydration obtained from \"\"soft\"\" to \"\"hard\"\" wheat flour (Triticum aestivum L.) produced by industrial milling or laboratory test milling.It describes the alveograph test and how to use a laboratory mill to produce flour in two stages: - Stage 1: preparation of the wheat grain for milling to make it easier to separate the bran from the endosperm (see Clause 7);- Stage 2: the milling process itself, including the break system involving three fluted rollers, reduction of particle size between two smooth rollers and the use of
This International Standard specifies a routine reference method for the determination of the moisture content of cereals and cereal products.This International Standard applies to: wheat, rice (paddy, husked and milled), barley, millet (Panicummiliaceum), rye, oats, triticale, sorghum in the form of grains, milled grains, semolina or flour.The method is not applicable to maize and pulses.NOTE For moisture content determination in maize, see ISO 6540[5]; and for pulses, see ISO 24557[7].
Guidance for the sampling in the case of non-uniformly distributed characteristics
Guidance for the sampling in the case of non-uniformly distributed characteristics
This International Standard specifies requirements for the dynamic or static sampling, by manual ormechanical means, of cereals and cereal products, for assessment of their quality and condition.It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirablesubstances, and parameters usually homogeneously distributed like those used to assess quality orcompliance with specification.It can be used to determine insects in a grain lot.It is applicable to sampling for assessment of the quality and condition of lots of genetically modifiedorganisms (GMO) but is inappropriate for the determination of the presence of adventitious geneticallymodified material in non-GM product.It is not applicable to seed grain.
