Paints and varnishes — Determination of pH value — Part 1: pH electrodes with glass membrane
ISO 19396-1:2017 specifies a method for laboratory measurement of the pH value of polymer dispersions and coating materials using pH electrodes with a glass membrane. ISO 19396‑2 specifies a method for measuring the pH value using pH electrodes with ion-sensitive field-effect transistor (ISFET) technology.
Synchronous belt drives — Automotive belts — Determination of physical properties
This International Standard specifies test methods for determining the physical properties of synchronous belts
used in driving engine parts, such as camshafts, fuel injection pumps, balancing shafts. These test methods
are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated
and qualified by dynamic laboratory and field testing.
