Pulps - Laboratory sheets - Determination of physical properties (ISO 5270:2012)
N EN ISO 5270
Annotation
This International Standard specifies the relevant International Standards to be used for the determination of physical properties of laboratory sheets made of all kind of pulps. It is applicable to laboratory sheets prepared in accordance with ISO 5269-1, ISO 5269-2 or ISO 5269-3.
In this International Standard, it is left to the pulp producer and the pulp user to agree upon which properties are relevant to be tested. The results are, if applicable, reported in index form.

Мякоть - Лабораторные листы - Определение физических свойств (ISO 5270:2012)
Этот Международный стандарт определяет соответствующие Международные стандарты, которые будут использоваться для определения физических свойств лабораторных листов, сделанных из всего вида мякоти. Это применимо к лабораторным листам, подготовленным в соответствии с ISO 5269-1, ISO 5269-2 или ISO 5269-3.
В этом Международном стандарте это оставляют пульповому производителю и пульповому пользователю согласовать, какие свойства необходимы быть проверенными. О результатах, если применимо, сообщают в форме индекса.
