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…
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…

Statistical interpretation of test results — Estimation of the mean — Confidence interval
Concerns the estimation of the mean of a normal population on the basis of a series of tests applied to a random sample of individuals drawn from this population when the variance of the population is unknown and calculation of the conficence interval for the population mean therefrom and from the standard deviation. Test method may be subject to systematic errors.
