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. This method is used to determine the capability of the furnace to meet the permissible temperature variation specified in the applicable product specification, or as agreed to by the purchaser and supplier of heat treat services. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Use of representative material to simulate product during survey is permitted.

Place them at the outer extremities, the center of the proposed working zone, and in areas of suspected variability in the proposed working zone. Attach survey test sensors to, or set them in the load.

It provides validation of temperature uniformity by a series of tests rather than a single test. Documentation of Survey Results 8.

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. A superscript aatm e indicates an editorial change since the last revision or reapproval.

Interpretation of Results and Establishment of the Working Zone 9. In each test, determine the temperature a919 pattern at one or more of the test locations. Starting time and chart speed shall be marked on the original temperature charts, 8. Current edition approved Oct. Results of the application of this test method shall be expressed as a variation from a temperature set point.

Furnace Survey Equipment 5. Details of this procedure shall be as agreed to between purchaser and supplier. 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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
