Sumary

Cereals. Determination of bulk density, called "mass per hectolitre".

La masse volumique dite "masse à l'hectolitre", également et traditionnellement appelée "poids spécifique", est un critère universellement utilisé dans le commerce des céréales et principalement du blé. Sa détermination, simple et facile à mettre en oeuvre, donne quelques indications sur la teneur en eau et les impuretés des céréales et le rendement en farine dans le cas des blés.

Cereals. Determination of bulk density, called "MASS per hectolitre".

La masse volumique dite "masse à l'hectolitre", également et traditionnellement appelée "poids spécifique", est un critère universellement utilisé dans le commerce des céréales et principalement du blé. Sa détermination, simple et facile à mettre en oeuvre, donne quelques indications sur la teneur en eau et les impuretés des céréales et le rendement en farine dans le cas des blés. Cependant, cette détermination fait l'objet de critiques nombreuses en raison de son caractère non scientifique ; les résultats étant fortement influencés par l'espace vide entre les grains conjointement mesuré par la méthode. D'autre part, les indications données par cette détermination peuvent être obtenues par des méthodes spécifiques et précises.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

mandatory clauses to satisfy,
non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
