Cereals - Determination of bulk density, called mass per hectolitre - Part 2: Method of traceability for measuring instruments through reference to the international standard instrument (ISO 7971-2:2009)

ISO 7971-2:2009 specifies a test method for ensuring the traceability of mass per hectolitre measuring instruments through reference to standard measurement instruments. The mass per hectolitre or bulk density is of commercial importance for grain cereals. Several types of instruments with varying performances exist for measuring it.
ISO 7971-2:2009 also specifies the performances required of national standards instruments, secondary standards instruments, and measuring instruments used in laboratories or in collection or storage silos.

Getreide - Bestimmung der Schüttdichte, sogenannte Masse je Hektoliter - Teil 2: Verfahren zur Rückverfolgbarkeit von Messgeräten mittels Referenz auf internationale Normalgeräte (ISO 7971-2:2009)

Dieser Teil von ISO 7971 legt ein Prüfverfahren zur Sicherstellung der Rückverfolgbarkeit der für die Messung
der Masse je Hektoliter angewendeten Geräte durch Bezugnahme auf ein internationales Normalgerät fest.
Die Masse je Hektoliter oder die Schüttdichte ist bei Getreidekorn von enormer wirtschaftlicher Bedeutung.
Zur Messung dieser Eigenschaft stehen verschiedene Messgeräte mit unterschiedlichem Leistungsverhalten
zur Verfügung.
Dieser Teil von ISO 7971 legt auch die Leistungsanforderungen fest, die die nationalen Normalgeräte, die
sekundären Normalgeräte, und die in Laboratorien oder in Annahme- oder Lagersilos verwendeten Messgeräte
erfüllen müssen.

Céréales - Détermination de la masse volumique, dite masse à l'hectolitre - Partie 2: Méthode de raccordement des instruments de mesure à l'étalon international (ISO 7971-2:2009)

L'ISO 7971-2:2009 spécifie une méthode d'essai pour assurer le raccordement des instruments de mesure de la masse à l'hectolitre aux étalons. La masse à l'hectolitre ou masse volumique présente un intérêt commercial pour les céréales en grains. Il existe plusieurs types d'instruments aux performances variables pour la mesurer.
L'ISO 7971-2:2009 spécifie également les performances exigées pour les étalons nationaux et secondaires ainsi que pour les instruments de mesure utilisés dans les laboratoires ou dans les silos de collecte ou de stockage.

Žito - Določanje prostorninske mase, imenovane hektolitrska masa - 2. del: Metoda sledljivosti za merilne instrumente glede na referenčni mednarodni etalonski instrument (ISO 7971-2:2009)

Ta del ISO 7971 opredeljuje preskusno metodo za zagotavljanje sledljivosti za merilne instrumente hektolitrske mase ob sklicevanju na standardne merilne instrumente. Hektolitrska masa oziroma gostota razsutega tovora je gospodarskega pomena za zrnata žita. Obstaja več vrst instrumentov z različnimi zmogljivostmi za njeno merjenje. Ta del ISO 7971 prav tako opredeljuje zmogljivosti, ki se zahtevajo za državne standardne instrumente, sekundarne standardne instrumente in merilne instrumente, uporabljene v laboratorijih ali v zbirkah ali skladiščnih silosih.
