Описание (английский):

ISO 16482-1:2013 specifies a method for determining the non-volatile content, by mass, of aqueous rosin-resin dispersions, using an oven. This method is applicable to resin dispersions having a softening point from 60 °C to 100 °C, measured in accordance with ISO 4625‑1 (ring-and-ball method).

Overview

EN ISO 16482-1:2016 specifies the oven method for determining the non-volatile-matter (NV) content of aqueous rosin-resin dispersions used as binders in paints and varnishes. The procedure measures NV by mass after controlled evaporation of water at elevated temperature and is applicable to resin dispersions with a softening point of 60 °C to 100 °C (measured in accordance with ISO 4625-1, ring-and-ball method).

This standard is part of ISO 16482 (which also includes a microwave method) and is adopted as a CEN standard for consistent binder quality control across coatings laboratories.

Key Topics

Scope and applicability: Oven method for aqueous rosin-resin dispersions with specified softening point range.

Principle: Evaporate water from a measured test portion at 135 °C in a non-convection oven and determine the mass of the residue to calculate NV as a percentage by mass.

Required apparatus:

Analytical balance accurate to 0.0001 g.
Aluminium dishes (bottom diameter (45 ± 5) mm; rim height ≤ 40 mm).
Non-convection oven maintained at (135 ± 3) °C and a convection oven at about 160 °C for dish drying.

Reagents: Chemically pure toluene and acetone for dish cleaning where required.

Sampling and repeatability: Follow ISO 15528 for representative sampling; perform determinations in triplicate and report the mean to one decimal place.

Applications

Quality control of binders for paints and varnishes to confirm non-volatile content and consistency between production batches.

Verification of raw material specifications where NV influences film formation, solids content, and coating performance.

Laboratory acceptance testing and routine production checks to support formulation decisions and compliance with product specifications.

Practical notes:

Dishes are cleaned (toluene then acetone), solvent-evaporated, and dried in the convection oven at about 160 °C for at least 24 h before use.

For each test, three dried dishes are cooled, weighed, filled with the specified test portion, dried at 135 °C (non-convection) until a constant weight is reached (minimum 45 minutes), cooled, and reweighed.

Calculate NV from the loss in mass and report the average of three valid results.

ISO 15528 - Sampling of paints, varnishes and raw materials; defines representative sampling procedures.

ISO 16482-2 - Microwave method (alternate technique for NV determination) - referenced as part of the ISO 16482 series.

This standard provides a reproducible, well-defined laboratory method to obtain reliable NV values for rosin-resin dispersions, supporting consistent binder evaluation and coating quality control.
