Binders for paints and varnishes — Determination of softening point — Ring-and-ball method
Specifies a method of test for resins (including rosin) and similar materials by means of the ring-and-ball apparatus. In general, with materials of this type, softening does not take place at a definite temperature. As the temperature rises, these materials gradually and imperceptibly change from brittle or exceedingly thick and slow-flowing materials to softer and less viscous liquids. For this…
Volatile organic liquids — Determination of boiling range of organic solvents used as raw materials
This method is applicable to organic liquids that boil between 30 and 300 C at normal pressure, and that are chemically stable and do not corrode the apparatus during the distillation such as hydrocarbons, esters, alcohols, ketones, ethers and similar products. The principle consists in distillation of a 100 ml test portion under prescribed conditions, systematic observation of thermometer…

This is applicable to distribution systems in which the hazards of stacking, vertical impact, horizontal impact, and vibration are encountered or are likely to be encountered. The following information shall be recorded in the order given: description of the trial, results of the trial, package, hazards in trial and general information.
The guidance describes methods for obtaining conditions for the successful keeping of shoots of the species Asparagus officinalis Linnaeus. It includes conditions of harvesting and putting into store, and optimum conditions, such as temperature, relative humidity, air circulation and storage life.
Hydrochloric acid for industrial use — Determination of oxidizing or reducing substances content — T...
The method is applicable to products having oxidizing or reducing matter contents equal to or greater than 0.001 % (m/m). The principle is based on detection of the presence of these matter by a preliminary qualitative test. In the case of oxidizing matter adding of potassium iodide solution and titration of the liberated iodine with sodium thiosulphate standard volumetric solution until the blue…
