ISO 15361 Pulps — Determination of Zero-Span Tensile Strength, Wet or Dry

ISO 15361 specifies the procedure for determining the tensile strength of laboratory sheets at a test span which is initially zero.

It is applicable to all kinds of fibres, including recycled fibres.

The laboratory sheets can be tested either dry, rewetted, or never dried.

For ISO 15361, use a tensile-testing machine capable of applying a load of (25 +- 2) N/s per 10 mm of jaw width

*** Before conducting ISO 15361 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
