TP012 - Pravilnik o metodah za določanje kakovosti žit, ki so predmet intervencijskega nakupa

This document specifies a test method for ensuring the traceability of bulk density, called “mass per
hectolitre”, measuring instruments through reference to standard measurement instruments. The
mass per hectolitre is of commercial importance for grain cereals. Several types of instruments with
varying performances exist for measuring it.
This document also specifies the performances required of national standards instruments, secondary
standards instruments, and measuring instruments used in laboratories or in collection or storage silos.

This International Standard provides general guidelines for the determination of nitrogen by the Kjeldahl method. It applies to food and feed products containing nitrogenous compounds that can be directly determined by the Kjeldahl method.
NOTE This measurement principle does not take into account the nitrogen from nitrates and nitrites.

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. It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances, and parameters usually homogeneously distributed like those used to assess quality or compliance with specification. It can be used to determine insects in a grain lot.

This International Standard specifies the determination of the a-amylase activity of cereals by the falling number (FN) method according to Hagberg-Perten. This method is applicable to cereal grains, in particular to wheat and rye and their flours, durum wheat and its semolina. This method is not applicable to the determination of low levels of a-amylase activity. By converting the FN into a liquefaction number (LN), it is possible to use this method to estimate the composition of mixtures of grain, flour or semolina with known FNs necessary to produce a sample of a required FN.

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 (Panicum miliaceum), rye, oats, triticale, sorghum in the form of grains, milled grains, semolina or flour. The method is not applicable to maize and pulses.
