Originally approved in This method is used to determine the capability of the furnace to meet the permissible temperature variation specified in the applicable product specification, or asttm agreed to by the purchaser and supplier aastm heat treat services. Combining values from the two systems may result in non-conformance with the standard. Survey documentation requirements, and the procedure used to subsequently establish the furnace working zone, are defined in this test wstm.
Current edition approved Oct. The rate of conveyance ast, be representative of normal operating conditions. Examples of these surveying techniques are listed below. Historical Version s – view previous versions of standard. Results of the aetm of this test method shall be expressed as a variation from a temperature set point. The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order as agreed upon by the purchaser and supplier.
Regardless of heat treat furnace type, or processing cycle, it may be necessary for users to know the temperature uniformity in the furnace and whether the material is processed in a zone within the furnace that is capable of meeting the applicable permissible temperature variation requirements.

Use of representative material to simulate product during survey is permitted. Details of awtm procedure shall be as agreed to between purchaser and supplier.
Place them at the outer extremities, the center of the proposed working zone, and in areas of suspected variability in the proposed working zone. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The values stated in each system are not exact equivalents; therefore, each system is to be used independently of the other, without combining values in any way. Documentation of Survey Results 8. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The working zone may be comprised of one or more heating zones in the furnace. Link to Active This link will always route to the current Active version of the standard.
It provides validation of temperature uniformity by a series of tests rather than a single test. 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. In each test, determine the temperature variation pattern at one or asgm of the test locations. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
