Liquefied phenol for industrial use — Determination of phenols content — Bromination method
The method is not specific for phenol. It determines tho total amount of material that can be brominated under the conditions of the test. It is applicable to mixtures of about 80 % (V/V) phenol and 20 % (V/V) water. The principle is based on reaction between phenol and bromine from a measured amound of standard bromide/bromate solution. Formation of tribromophenol, follwed by iodometric…
Sodium and potassium silicates for industrial use — Determination of dynamic viscosity
The determination is carried out by using a rotary viscometer. It is applicable to liquid products, the dynamic viscosity of which lies between 10 and 80000 mN.s/m2. The principle consists in the determination at a temperature of (20 +- 0,2) °C by measuring the couple required to overcome the resistance exercised by the viscous liquid on an immersed element rotating within it at a constant…
Applies to insulated conductors used in industrial installations and the equipment which forms part of them. Not applicable to insulated conductors constituting the terminals of electrical apparatus.
