ISO 5351

Limiting viscosity of pulp is a key product parameter both for final product QC testing and for product specification for the purpose of international commodity trading. ISO 5351:2010 is currently the most widespread test procedure for pulp viscosity.

Based on this document, it will be possible to device a robust and fit for purpose Standard Operating Procedure for the pulp testing. ISO 5351:2010 may be purchased here:
