Tissue paper and tissue products - Part 12 : determination of tensile strength of perforated lines - Calculation of perforation efficiency

ISO 12625-12:2010 specifies a test method for the determination of the tensile strength of perforated lines of tissue paper. It uses a tensile-testing apparatus operating with a constant rate of elongation.This method is only used for measuring machine-direction tensile strength, that is for cross-direction perforations on tissue paper.The calculation of perforation efficiency is also specified in ISO 12625-12:2010.

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!
