ASTM D129

Standard Test Method for Sulfur in Petroleum Products (General High Pressure Decomposition Device Method)
his standard details the general bomb test method for determination of the amount of sulfur in lubricating oils with additives, additive concentrates, lubricating greases, and other petroleum products with low volatilities. This test method entails oxidizing samples by combustion in a bomb containing oxygen under pressure. The amount of sulfur is determined by gravimetry. Materials needed for the test include a combustion bomb, sample cup, firing wire, ignition circuit, and a cotton wicking or nylon sewing thread. All reagents, samples, and other chemicals used for the test should conform to the required concentration and purity.

ASTM D240-17

Standard Test Method for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter
This test method covers the determination of the heat of combustion of liquid hydrocarbon fuels ranging in volatility from that of light distillates to that of residual fuels.

ASTM D808-16

Standard Test Method for Chlorine in New and Used Petroleum Products (High Pressure Decomposition Device Method)
This test method covers the determination of chlorine in lubricating oils and greases, including new and used lubricating oils and greases containing additives, and in additive concentrates. Its range of applicability is 0.1 m% to 50 m% chlorine. The procedure assumes that compounds containing halogens other than chlorine will not be present.

ASTM D2382

Test Method for Heat of Combustion of Hydrocarbon Fuels by Bomb Calorimeter (High-Precision Method)

ASTM D3286

Standard Test Method for Gross Calorific Value of Coal and Coke by the Isoperibol Bomb Calorimeter
This test method covers the determination of the gross calorific value of coal and coke by the isoperibol bomb calorimeter.

ASTM D4809

Standard Test Method for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter
This test method covers the determination of the heat of combustion of hydrocarbon fuels. It is designed specifically for use with aviation turbine fuels when the permissible difference between duplicate determinations is of the order of 0.2 %. It can be used for a wide range of volatile and nonvolatile materials where slightly greater differences in precision can be tolerated.

ASTM D5865-13

Standard Test Method for Gross Calorific Value of Coal and Coke
This test method pertains to the determination of the gross calorific value of coal and coke by either an isoperibol or adiabatic bomb calorimeter.

DIN 51577

Determination of chlorine and bromine contents of petroleum products by energy-dispersive x-ray spectrometry using a miniature spectrometer

IP 61

Determination of sulfur — High pressure combustion method
This standard specifies a procedure for the determination of sulfur in the range 0,09 % (m/m) to 5,5 % (m/m) in petroleum products including lubricating oils containing additives, additive concentrates, and lubricating greases, that cannot be burned completely in a wick lamp. This standard is applicable to any petroleum product sufficiently low in volatility that it can be weighed accurately in an open sample boat. This standard is not applicable to samples containing elements that give residues, other than barium sulfate, which are insoluble in dilute hydrochloric acid solutions and would interfere in the precipitation step.

ISO 1716

Reaction to fire tests for products -- Determination of the gross heat of combustion
Specifies a method for the determination of the gross heat of combustion of products at constant volume in a bomb calorimeter.
