In addition to meeting the requirements specified in their individual material specifications, issued under the jurisdiction of ASTM Committee C16, these insulations must pass the preproduction test requirements of Test Method Cfor stress corrosion effects on austenitic stainless steel, and the confirming quality control, chemical requirements, when tested in accordance with the Test Methods C The values given in parentheses are mathematical conversions to SI units that are provided for c759 only and are not considered standard.
The material shall conform to the established requirements of the basic material specification. Referenced Documents purchase separately The documents listed below astj referenced within the subject standard but are not provided as part of the standard.

Understanding ASTM Test Methods Evaluating Thermal Insulations and Corrosion of Metals
Re your insulation vs. Many facilities departments tasked with creating and implementing an effective CUI-inspection program report very limited budgets and available personnel to carry out this critically important task, which must continue in perpetuity. ASTM International plays an important role in providing the technical data and physical properties for a broad range of materials, including insulation.
The rates are compared to various control solutions including DI water and 1-ppm and 5-ppm chloride solutions. While the older corrosion test strictly relies on visual results, C provides objective, quantifiable data of the actual metal loss due to corrosion caused by the chemical formulation of the various insulations.
The material shall conform to the established requirements of the basic material specification. Hope you anyone could enlighten me. One thing many fail to realize is that ASTM is a consensus group, meaning that edits, additions, or deletions to a document must receive approval from every member that votes on the issue. Preproduction corrosion test and chemical analysis shall be performed to conform to the specified requirements.
Also, remember that external sources of chlorides usually cause more damage than the ppm chlorides found in insulation materials. It is informational only and not an official part of the standard; qstm full text of the standard itself must be referred to for its use and application.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Are you sure you want to empty the cart? The physical and chemical requirements shall conform to the requirements of the basic material specification. The safe operation of oil refineries in the United States is under constant r Link to Active This link will always route to the current Active version of the standard. This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment.
Now what confuses me is that does the claim of this manufacturers possibly real and is the required specification of not less than 5ppm attainable? Unfortunately, CUI can be very difficult to detect, often only being discovered after it has caused significant damage.
Leachable Chloride Content of Thermal Insulation
Helps manufacturers ensure their chemical formulations help reduce the potential for CUI being caused by the insulation itself. Search book title Enter keywords for book title search. Your stated minimum operating temperatures of C are also above where we would anticipate chloride SCC issues unless the component cycles frequently. As these standards frequently take extensive amounts of time to gain consensus within each committee, the absence of a particular test method should not call into question the corrosion performance of any insulation standards that do not yet reference the test.
The coupons are weighed before the test, and are weighed again after the test once the coupon has been cleaned to remove corrosion products formed during the test.
