Guide for Loading Dry-Type Distribution and Power Transformers
1. Scope
1.1 This Standard covers general recommendations for loading dry-type distribution and power transformers that have in sulation systems limited to 150, 185 and 220°C maximum hottest-spot operating temperatures, manufactured in accordance with CSA Standard C9, Dry-Type Transformers.
This standard covers the construction and performance of domestic
conversion burners for use with natural gas and propane with
inputs of not more than 400 000 Btu/h (120 kW).
1. Scope
1.1 This Standard applies to single-phase and 3-phase dry-type transformers within the limits of the electrical ratings listed in Clauses 6.2 and 6.3, and intended to be used in accordance with the service conditions for dry-type transformers outlined under Appendices A and B.
Note: For information on the loading of dry-type transformers see CSA Standard C9.1, Guide for Loading…
Applies to all kinds of pulp delivered in bales or rolls, and is recommended for use when sampling for all kinds of testing purposes except for the determination of saleable mass. If the pulp is to be tested for saleable mass, in addition to other properties, the gross sample obtained according to the appropriate International Standard for sampling saleable mass may also be used for the other…
This second edition cancels and replaces the first edition (i. e. ISO 2080:1973). Includes terms widely used in the science and industry of elektrodeposition and metal- finishing. In addition to terms used in the three official ISO languages (English, French and Russian), this International Standard includes the equivalent terms in the German language.Elektrolytisches Herstellen von…
Ethanol for industrial use — Methods of test — Part 6: Test for miscibility with water
The principle of the procedure consists in addition of water to a test portion, under specified conditions, and examination for opalescence against a black background with side illumination, using a second Nessler cylinder containing water as the standard. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which they constitute a technical…
Ethanol for industrial use — Methods of test — Part 7: Determination of methanol content (methanol c...
The principle is based on the conversion of methanol present in a test portion to formaldehyde by oxidation. The oxidation is carried out with a solution of potassium permanganate in phosphoric acid. Reaction of the formaldehyde formed with chromotropic acid (4,5-dihydroxynaphthalene-2,7-disulphonic acid). Photometric measurement of the violet coloration obtained at a wavelength of about 570 nm…

The principle is based on the conversion of the methanol present in a test portion to formaldehyde by oxidation with a solution of potassium permanganate in phosphoric acid. Reaction of the formaldehyde formed with Schiff reagent. Visual comparison of the colour obtained with the colours of standard colorimetric solutions containing known quantities of formaldehyde. - International Standards ISO…
Ethanol for industrial use — Methods of test — Part 10: Estimation of hydrocarbons content — Distill...
The principle is based on distillation of a test portion in the presence of water, addition to the distillate of a saturated sodium chloride solution and measurement of the volume of insoluble hydrocarbons. A Hempel fractionating column with Liebig condenser is used for the distillation. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which…
