Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is the responsibility atsm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Persons using this practice must have a knowledge of the practical application of heat transfer theory relating to thermal insulation materials and systems. Register now while it’s still free! In the cylindrical coordinate system, Practice C can be applied to radial c860 flows for all types of piping circuits.

The range and quality of the astn and thermal property data of the materials comprising the thermal insulation system limit the calculation accuracy. Download Now Defense manufacturing is all about project manufacturing and project accounting. When an international standard for piping and insulation sizing occurs, this practice can be rewritten to meet those needs.

ASTM-C, –

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Are you sure you want to empty the cart? Because of this averaging, portions of the surface will have different surface temperatures and heat flux rates from the average. Therefore, no SI version of the practice has been prepared, because a standard SI equivalent of this practice would be complex. Are you an Engineering professional?

Also, phase change of a gas, liquid, or solid within a solid matrix or phase change by other mechanisms will provide abrupt changes in the temperature dependence of thermal conductivity. Land Use and Development. The exterior surface temperature of the insulation is often shown to provide information on personnel protection or surface condensation. This cost can be substantially reduced by the use of accurate engineering data tables, or available computer analysis tools, or both.

Infrared inspection, in-situ heat flux measurements, or both are often used in conjunction with Practice C to evaluate insulation system performance and durability of operating systems. The wind part is what I want to confirm. For example, the condensation of the gaseous portions of thermal insulation in extremely cold conditions will have an extremely influential effect on the apparent thermal conductivity of the insulation.

Air blowing across real objects often follows flow directions and velocities much different from the direction and velocity aastm the main free stream. Link to Active This link will always route to the current Active version of the standard. There were no books found for the applied search filters.

An executable version of a program based on this standard may be obtained from ASTM. The computer program is intended for flat slab, pipe and hollow sphere insulation systems.

Also, additional calculations may be desired to include other data such as system costs or economic thickness. Download Now White Paper: With the existence of radiation and convection modes of heat transfer, the measured value should be called apparent thermal conductivity as described in Terminology C 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.
