ASTM COLD SOAK TEST

ASTM D6751 Cold Soak Test

This section of our website is intended to educate Biodiesel Producers on the ASTM D6751 Cold Soak Test.  As new information arrives we will post it here to keep our customers informed.  Please Contact Us if you would like to be part of our monthly email letters.


 The ASTM D6751 Cold Soak Test

 

Cold Soak Filtration
• Part of ASTM D6751, quality standard for biodiesel fuels. Measures the diesel’s ability to clog fuel filters after being subjected to cold temperatures
• Performance based test, where results are reported in seconds (The lower the number, the faster the fuel flowed during the test)
 
Every biodiesel producer and blender must pass this (and other) tests after October 1st, 2009

 
Test Overview - ASTM D 7501 - 09 Cold Soak
 
300mL of test fuel is chilled to 40F for 16hrs
• After 16hrs, it is allowed to come to room temperature on its own (no heat, no energy)
• Fuel is put into funnel and pulled through a 0.7μ (micron) glass fiber patch with stainless steel support pulled by a vacuum and the pressure shall be between71.1 and 84.7 kPa (21 and 25 in. of Hg) below atmospheric.
• The amount of time it takes to empty the funnel (in seconds) is recorded
 
• Currently, Less than 360 sec. is required to pass
• Less than 200 sec. is recommended for -10° C or less climates.

IRS Delays Biodiesel ‘Cold Soak’ Deadline for Tax Credit Eligibility

By Ron Kotrba


The Internal Revenue Service pushed back its deadline six months requiring biodiesel to meet the latest version of ASTM D 6751 to legitimately claim the dollar-per-gallon tax credit. The latest version of D 6751 includes a Cold Soak Filtration Test. As a result of IRS’s extension, biodiesel meeting the previous version of D 6751 – the version without a CSFT – is still eligible until IRS’s new enforcement date, Oct. 1

Part III - Administrative, Procedural, and Miscellaneous
Modification of Notice 2008-110; ASTM standards for biodiesel
Notice 2009-34
SECTION 1. PURPOSE
This notice extends the transitional rule set forth in Section 2(c) of Notice 2008-
110, 2008-51 I.R.B. 1298, to September 30, 2009.
SECTION 2. BACKGROUND
(1) Sections 40A, 6426, and 6427(e) of the Internal Revenue Code (Code)
provide tax incentives for the production, sale, and use of biodiesel and biodiesel
mixtures. Section 40A(d)(1) of the Code defines biodiesel as monoalkyl esters of long
chain fatty acids derived from plant or animal matter which meet (i) the registration
requirements for fuels and fuel additives established by the Environmental Protection
Agency under section 211 of the Clean Air Act (42 U.S.C. 7545), and (ii) the
requirements of ASTM D6751.
(2) Effective on October 13, 2008, the American Society of Testing and Materials
revised the requirements of ASTM D6751 by adding a cold soak filtration test for
biodiesel (the October 13, 2008 revision).
2
(3) Section 2(c) of Notice 2008-110 provides a transitional rule to address this
new ASTM D6751 requirement. Under the transitional rule, if a taxpayer’s claim for
biodiesel incentives is related to the production, sale, or use of biodiesel or a biodiesel
mixture before April 1, 2009, a certification that the biodiesel covered by the claim
meets the requirements of ASTM 6751 is valid if the biodiesel meets the requirements
of ASTM 6751 as in effect either before or after the October 13, 2008, revision.
However, if the claim is related to the production, sale, or use on or after April 1, 2009,
the certification of the biodiesel covered by the claim is valid only if the biodiesel meets
the requirements of ASTM 6751 as in effect after the October 13, 2008 revision.
SECTION 3. EXTENSION OF TRANSITIONAL RULE
This guidance extends the transitional rule set forth in Section 2(c) of Notice
2008-110 through September 30, 2009. Therefore, if a taxpayer’s claim for biodiesel
incentives relates to the production, sale, or use of biodiesel or a biodiesel mixture and
the production, sale, or use occurs before October 1, 2009, a certification that the
biodiesel covered by the claim meets the requirements of ASTM D6751 is valid if the
biodiesel meets the requirements of ASTM D6751 as in effect either before or after the
October 13, 2008 revision that added the cold soak filtration test for biodiesel. If a claim
relates to the production, sale, or use of biodiesel or a biodiesel mixture and the
production, sale, or use occurs on or after October 1, 2009, a certification that the
biodiesel covered by the claim meets the requirements of ASTM D6751 is valid only if
the biodiesel satisfies the requirements of ASTM D6751 as in effect after the October
13, 2008, revision that added the cold soak filtration test for biodiesel.

SECTION 4. EFFECT ON OTHER DOCUMENTS
Notice 2008-110 is modified.
SECTION 5. DRAFTING INFORMATION
The principal author of this notice is Charles J. Langley, Jr. of the Office of
Associate Chief Counsel (Passthroughs and Special Industries). For further information
regarding this notice contact Charles J. Langley, Jr. on (202) 622-3130 (not a toll-free

Cold Soak Filtration Test Mandated For Biodiesel Testing

Cold Soak Filtration Test Mandated for Biodiesel Testing - Open Article

 
The newest testing requirement for biodiesel fuel testing is the cold soak filtration test. The procedure was added to the ASTM Method in October 2008. It is designed to improve purity standards in alternative fuels for consumers.
Biodiesel fuel is a non-petroleum based fuel that is made by the transesterification of vegetable oil or animal fat. It can be used to run unmodified diesel engine vehicles. It differs from straight vegetable oil or waste vegetable oil, which require the use of a converted engine.
