Various organizations publish standards for thermal insulation materials and for testing and applying the materials. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
ASTM C – 18a Standard Specification for High-Temperature Fiber Blanket Thermal Insulation
Work Item s – proposed revisions of this standard. The liquid binder consists of a mixture of both organic and inorganic colloidal silica materials, and is typically added in sufficient quantity to provide the fibers with necessary adhesion to the applied surface; cohesion to one another; and the required physical properties of the installed, dry insulation. These AES fibers are designed to be bio-soluble i. The insulation shall also be tested for non-fibrous content, linear shrinkage, and tensile strength.
The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
However, for a highly non-linear relationship i. The basic types of materials are loose, inorganic fibers either RCF or AES combined with a liquid, asm chemical binder. Proceed to Checkout Continue Shopping.
Conclusions and Recommendations Material and test standards for thermal insulation materials provide valuable support to specifiers, designers, atsm users working with high-temperature products. The materials appear d892 be simple but are highly engineered to optimize different properties, such as thermal performance, high-temperature performance, compressive strength, rigidity or flexibility, water repellence, flame spread prevention, inhibition of metal surface corrosion, and various health and safety considerations.

Pneumatically applied high-temperature fibers are typically used on applications where it would be difficult to adhere blankets to a surface. If the document is revised or amended, you will be notified by email. Their business histories over the first 11 years show striking similarities—and differences:.
Subscription pricing is determined by: Figure 1 shows these values graphically so they can be more easily compared.
Standard test procedures are used to measure performance as determined by material properties. The answer appears to have two roots: Add to Alert PDF. For comparison purposes, the maximum thermal conductivity of Grade 3 material is 0. This standard is not included in any packages.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. You may delete a document from your Alert Profile at any time.
Why do the different thermal test procedures offer two different sets of results for the same material, tested at the same mean temperature? The two methods are thus complementary for application over the entire C temperature range.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. The liquid binder is made from inorganic materials: In most cases, the values for a specific grade at a specific mean temperature are significantly different.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
If two companies manufacturing the same generic material use different test procedures, it is challenging and perhaps even impossible for users to compare performance of the two materials.

The guarded hot plate test method could be considered a primary resource for generating new asttm conductivity data, and C tests could sstm used for the top end of the temperature range. Thermal conductivity data tabulated in ASTM C is based on studies made more than 30 years ago; it may be time to reexamine the standard to enhance its usefulness. Figure 2 presents the same information graphically.
Jack calculated his average the same three awtm, but he got the same result each time: Already Subscribed to this document. Standards Subsctiption may be the perfect solution. Follow Us On Twitter http: C lists quite different thermal conductivity values one for each of the two methods for this grade, shown in Table 2. Need more than one copy?
What Is Average?
The standard contains requirements for thermal conductivity, density, maximum use temperature, non-fibrous shot content, linear shrinkage, and tensile strength. This abstract is a brief summary of the referenced standard. Also, this type of fiber insulation is typically dimensionally stable with exposure to the maximum rate atsm for the particular type I, II, or III.
