Butadiene for industrial use — Determination of active tert-butyl-catechol (TBC) (4- (1,1- dimethyle...
The active TBC in a test portion is extracted by mixing with a solution containing m-nitrophpenol (as the internal standard) and evaporating the butadiene. The TBC and m-nitrophenol are separated by high-performance liquid chromatography and detected by UV: The peak areas or peak heights are measured and the TBC content is determined by using a calibration graph. The polymerization inhibitor TBC…

internal diameter of 32 mm for use on portable and wheeled fire
extinguishers, hand hose line fixed extinguishing systems, and
also as booster hose on fire apparatus.
Cinematography — A-chain frequency response for reproduction of 35 mm photographic sound — Reproduct...
This International Standard specifies the A-chain electrical frequency response characteristic for photographic Sound reproduction in motion-picture control rooms and indoor theatres. lt is intended, in conjunction with ISO 2969, to assist in the standardization of recording monitor and reproduction characteristics of motion-picture Sound dubbing theatres, review rooms and indoor theatres. This…
Metallic and other non-organic coatings — Review of methods of measurement of thickness
This second edition cancels and replaces the first edition (i. e. ISO 3882:1978). Applies to both metallic and non-metallic substrates. It is limited to tests already specified, or to be specified, in International Standards, and excludes certain tests which are employed for special applications. Includes five non-destructive methods and four destructive methods.
Information Processing Systems - Open Systems Interconnection - Basic
Reference Model
This National Standard of Canada is equivalent to International Standard ISO
7498-1984.
1 Scope and field of application
This International Standard describes the Reference Model of Open Systems
Interconnection. It establishes a framework for coordinating the development
of existing and future standards for the interconnection of systems and is

Electrical Equipment for Flammable and Combustible Fuel Dispensers
1. Scope
1.1 This Standard applies to the electrical features of power-operated dispensers for petroleum-based liquids, including propane and lighter-than-air fuel such as natural gas, used as fuel in internal combustion engines, where such devices are operated at 750 V and less, in accordance with the Rules of the Canadian Electrical Code, Part I, and are intended to dispense the fuel directly…
Oils of sassafras and nutmeg — Determination of safrole and cis- and trans-isosafrole content — Gas ...
A small quantity of the oils is analyzed by gas chromatography under specified conditions on a packed column. The safrole and cis- and trans-isosafrole contents are determined by using the internal standard method. As stationary phase are used polydimethylsiloxane, or polyethylene glycol 20000. Operating temperatures: Oven: isotherm about 100 °C when using polydimethylsiloxane; isotherm about 125…
Oils of thujone-containing Artemisia and oil of sage (Salvia officinalis Linnaeus) — Determination o...
A small quantity of the oils is analyzed under specified conditions. The alpha- and beta-thujone contents are determined by using the internal standard or addition method. As stationary phase are used cyanopropyl methylphenyl methyl silicone, or trifluoropropylmethyl silicone, or polyethylene glycol 1500. Operating temperatures: Oven: isotherm about 100 °C when using cyanopropyl methylphenyl…
Oil of calamus — Determination of cis-beta-asarone content — Gas chromatographic method on packed co...
A small quantity of the oil is analyzed under specified conditions. The cis-beta-asarone contents is determined by using the internal standard or addition method. As stationary phase polyethylene glycol 20000 is used. Operating temperatures: Oven: isotherm about 190 °C. Injection system and detector: about 170 °C.
