Fluid power systems and components — Multiple lip packing sets — Methods for measuring stack heights
Specifies methods for measuring sealing devices having more than one seal in the set. Specifies methods for measuring stack height in order to determine that the sets are to an acceptable dimensional standard. Does not specify the dimensions for packing sets or their components. Describes three acceptable methods, and figure 1 shows a typical measuring device for the methods 1 and 2, the figures…
This Guide establishes certain basic principles for the functioning of a system of product information. It concerns those cases where the information is based in general on standards approved or recognized by ISO, IEC or the national standards body, and is one of a series dealing with various aspects of consumer information, including comparative testing and marks of conformity with standards.
Acetic anhydride and butan-1-ol for industrial use — Determination of bromine number
The principle consists in treatment of a test portion in acid solution with excess standard volumetric potassium bromide-potassium bromate solution, addition of potassium iodide solution and titration of the liberated iodine with a standard volumetric solution of sodium thiosulphate. - Replaces ISO Recommendation R 761-1968.
Sodium hexafluorosilicate for industrial use — Determination of free acidity and total hexafluorosil...
With respect to the free acidity, applicable to products having contents, expressed as H2 SiF6 , equal to or more than 0,1 % (m/m). First, determination of the free acid contents by titration of an ice-cooled test portion with a standard volumetric sodium hydroxide solution in the presence of potassium nitrate and using bromothymol blue as indicator, then, followed by titration at near boiling…
Diffusable Hydrogen in Mild Steel and Low-Alloy Steel Weld Metals: Test
Method
1. Scope
1.1 The purpose of this Standard is to provide a test method for measuring
the content of diffusible hydrogen in deposited weld metal.
Note: In order to obtain the total hydrogen content, it would be
necessary to obtain the residual content by hot extraction at 650°C
under vacuum or using a carrier gas method.
1.2 This assessment shall…
Electromagnetic Interference Measuring Instrument - C.I.S.P.R. Type
1. Scope
1.1 This Standard sets forth the characteristics of an instrument conforming to C.I.S.P.R. requirements for the measurement of electromagnetic interference, both conducted and radiated, in the frequency range 0.15 MHz - 1000 MHz, as set for th in related CSA Standards on Tolerable Limits of Electromagnetic Interference. The frequency range, methods of use, and tolerable limits are…
Surface active agents — Determination of free alkalinity or free acidity — Titrimetric method
The determination is carried out in the following way: Titration of an ethanolic or propanolic solution of the product with a standard volumetric potassium hydroxide or hydrochloric acid or sulphuric acid solution whichever is appropriate, in the presence of phenolphthalein as indicator.
Surface active agents — Determination of alkalinity — Titrimetric method
A clear solution of the substance is titrated with a standard volumetric hydrochloric acid solution, in the presence of methyl orange or bromophenol blue as indicator. This method is only applicable when so indicated in the specific standard for each product; in particular, it is not suitable for products containing soaps.
Formic acid for industrial use — methods of test — Part 7: Determination of low contents of other vo...
The principle consists in a decomposition of most of the formic acid in a test portion by sulphuric acid an of the remainder by chromic acid. Steam distillation of acetic acid and/or other volatile acids and titration of the distillate with standard volumetric sodium hydroxide solution in the presence of phenolphthalein as indicator. The method is applicable to products containing less than 0,5…
