Paper and board - Determination of bending resistance - Part 1 : constant rate of deflection

ISO 2493-1:2010 specifies procedures, based on the two-point loading principle, for determining the bending resistance of paper and board. ISO 2493-1:2010 applies to the measurement of the bending resistance within the range 20 mN to 10 000 mN. It is not applicable to corrugated board but can be applicable to the components of such board. The bending angle is 15° and the bending length is 50 mm. For samples having a bending resistance that is too low to measure with a bending length of 50 mm, a shorter bending length, i.e. 10 mm, can be used. For boards that tend to be permanently deformed if bent through 15°, the half bending angle, i.e. 7,5°, can be used.

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!
