Gives construction and performance requirements for hotel and
restaurant deep fat fryers for use with natural gas, manufactured
gas, mixed gas, liquefied petroleum gases and LP gas-air
mixtures. The standard also covers approval of all electrical
equipment, wiring and accessories.
Methyl ethyl ketone, isobutyl methyl ketone and isoamyl ethyl ketone for industrial use — Determinat...
Acetylation of a test portion with acetyl chloride and determination of the alcohol equivalent to the acetyl groups that have reacted by titration with standard volumetric sodium hydroxide solution in the presence of phenolphthalein. Correction of the acidity of the sample.
Control of Electrochemical Corrosion of Underground Metallic Structures
1. Scope
1.1 The provisions of this Standard, forming a part of the Canadian Electrical Code, Part III, embody the applicable principles and general practices where underground metallic structures are subject to the risk of electro-chemical corrosion.
1.2 This Standard is issued for the guidance of all parties owning, controlling, or operating grounded electric systems and subsurface…
1. SCOPE
1.1 This Standard applies to complete, flue-connected, oil-fired warm air
appliances, irrespective of the heating capacity or the type of burner used.
1.2 The requirements given herein apply to appliances intended for
installation with the appliance base placed upon the floor, except as provided
for in Clause 1.4; and intended to be used with pipes or ducts for the…
Furfural for industrial use — Determination of total carbonyl compounds — Volumetric method
Reaction between hydroxylammonium chloride and carbonyl groups in a test portion, followed by determination of the hydrochloric acid liberated by titration with standard volumetric sodium hydroxide solution in the presence of bromophenol blue as indicator.
Methyl ethyl ketone for industrial use — Examination for residual odour
The principle of examination is the comparison of the odour of the sample with that of an agreed reference standard. If there is no odour after the butanone has been evaporated the product is without any residual odour.
Tritolyl phosphate for industrial use — Determination of acidity to phenol red — Volumetric method
Specifies the titration of any acidity present in an ethanolic solution with standard volumetric sodium hydoxide solution in the presence of phenol red as indicator. The end point of the titration corresponds to the formation of the salt Na2 HPO4 .
Tritolyl phosphate for industrial use — Determination of apparent free phenols content — Volumetric ...
The method specified determines only those phenols capable of reacting at the 2nd, 4th and 6th position (-OH = 1). The procedure consists in extraction of free phenols from a test portion with sodium hydroxide solution. Bromination of these phenols with potassium bromide-bromate solution in an acid medium and determination of the excess bromine after reaction with potassium iodide by titration…
