NF ISO 3105
Glass capillary kinematic viscometers. Specifications and operating instructions.
Cancels and replaces the first edition (1976). Gives specifications and operating instructions for glass capillary viscometers widely used for the determination of kinematic viscosity of petroleum products by the procedure described in ISO 3104. Also describes the calibration of these viscometers. These viscometers are modified Ostwald viscometers, suspended-level viscometers and reverse-flow viscometers.

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!
