Significance and Use
This test method may be used to determine the total sulfur content of unknown organic samples or to assay known sulfur containing organic compounds.
This test method may be used on organic materials in which the complete conversion of sulfur to sulfate can be accomplished by sodium peroxide bomb ignition.
This test method assumes that sulfate is quantitatively measured by precipitation with barium chloride solution.
Scope
1.1 This test method covers the determination of sulfur in organic compounds by sodium peroxide bomb ignition. It is intended for application to samples of organic materials containing more than 0.5 % sulfur. The presence of iron may require a separation such as is described.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 6.6.2, Section 7 and 8.3.
Note 1—A Test method baseed on an oxygen bomb combustion of petroleum products is described in Test Method D 129.
1.3 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

What is a Redline?
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
additions
deletions
and other changes between the two standards.
Save Time and Trouble!With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
PriceWhen you select the "Standard + Redline" option you get both documents! Best of all, the cost of a Standard + Redline is only slightly more than buying the Active Standard by itself.
Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). Transit
times average 3 to 5 business days. Please be aware that UPS will not deliver packages to Post Office Boxes.
International orders are delivered via courier post services which can be either a postal service, courier
service, or a combination of both. Standard Service is untraceable. Please allow 4-7 weeks for delivery.
Please be aware that carriers will not deliver packages to Post Office Boxes. Because of the variability of
customs processes and procedures in different countries, ASTM International cannot guarantee transit times to
international destinations. Customs duty and taxes are the responsibility of the consignee.
