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/FDIS 7971-2:2018)

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.

Getreide - Bestimmung der Schüttdichte, sogenannte Masse je Hektoliter - Teil 2: Verfahren zur Rückverfolgbarkeit von Messgeräten mittels Referenz auf internationale Normalgeräte (ISO/FDIS 7971-2:2018)

Dieses Dokument legt ein Prüfverfahren zur Sicherstellung der Rückverfolgbarkeit der für die Messung der Schüttdichte, bezeichnet als „Masse je Hektoliter“, angewendeten Geräte durch Bezugnahme auf ein Normal¬messgerät fest. Die Masse je Hektoliter ist bei Getreide von wirtschaftlicher Bedeutung. Zur Messung dieser Eigenschaft stehen verschiedene Messgeräte mit unterschiedlichem Leistungsverhalten zur Verfügung.
Dieses Dokument legt auch die Leistungsanforderungen fest, die die nationalen Normalgeräte, die sekun-dären Normalgeräte und die in Laboratorien oder in Annahme  oder Lagersilos verwendeten Messgeräte er¬füllen 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/FDIS 7971-2:2018)

Le présent document spécifie une méthode d'essai pour assurer le raccordement des instruments de mesure de la masse volumique, dite «masse à l'hectolitre» aux étalons. La masse à l'hectolitre présente un intérêt commercial pour les céréales en grains. Il existe plusieurs types d'instruments aux performances variables pour la mesurer.
Le présent document 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 7971-2:2019)

Ta dokument določa preskusno metodo za zagotavljanje sledljivosti instrumentov za merjenje prostorninske mase, imenovane »hektolitrska masa«, glede na referenčne etalonske merilne instrumente. Hektolitrska masa je komercialno pomembna za žito v zrnju. Za merjenje je na voljo več vrst instrumentov z različnimi zmogljivostmi.
Ta dokument določa tudi zmogljivosti, ki se zahtevajo od nacionalnih etalonskih instrumentov, sekundarnih etalonskih instrumentov in merilnih instrumentov, ki se uporabljajo v laboratorijih ali v zbirnih oziroma skladiščnih silosih.
