The material shall conform to the established requirements of the basic material specification. January 30, – February 2, Where: Historical Version s – view previous versions of standard.
Unlike ferrous iron-based steel that rusts, stainless steel will fail through a process known as external stress corrosion cracking ESCC. As long as a given product meets the insulation-specific minimum requirements, it can be considered an adtm material to bid on the project.
In contrast, material standards are the specified results that must be achieved via the applicable test methods in order to claim that a particular insulation material is compliant with the ASTM standard.
The rates are compared to various control solutions including DI water and 1-ppm and 5-ppm chloride solutions. This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. Other methods involve removing a small percentage of the insulation in CUI-prone areas, inspecting the base metal, and then re-covering the exposed pipe with new insulation and cladding.
C Terminology Relating to Thermal Insulation. This means that it is possible for aastm different insulation materials to meet their own minimum c79, but one may suit a particular application better than the other as to one or more attributes.

If the steel shows any cracking under a microscope, the insulation will fail.

Nails, Spikes, and Staples. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
One thing many fail to realize is that ASTM is a consensus cc795, meaning that edits, additions, or deletions to a document must receive approval from every member that votes on the issue.
Most ASTM material standards for industrial insulation contain one or more of these test methods regarding corrosion.
Leachable Chloride Content of Thermal Insulation
Test methods are exactly that—they lay out a plan to test, evaluate, and report specific physical properties. It has been required that they are to contain not more than 5ppm of Cl content. Copyright Compu-tecture, Inc. Land Use and Development.
Link to Active This link will always route to the current Active version of the standard. This also helps engineers know that every word of the standard is deliberate and agreed upon by all of the members of the committee. So the insulation needs to be tight from moisture intrusion.

Preproduction corrosion test and chemical analysis shall be performed to conform to the specified requirements. This abstract is a brief summary of the referenced standard. The material shall conform to the established requirements of the basic material specification.
The coupons are weighed astmm the test, and are weighed again after the test once the coupon has been cleaned to remove corrosion products formed during the test.

So please participate and share knowledge just as you have in the past. Also, remember that external sources of chlorides usually cause more damage than the ppm chlorides found in insulation materials. It has a long reputation as a credible, non-biased source for test methods and material standards, and as such can be an essential resource for specifiers who are looking for insulations with excellent CUI performance.
In addition to meeting the requirements specified in their individual material specifications, issued under the jurisdiction of ASTM Committee C16, these aetm 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
