Significance and Use 4. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only. This procedure is essential when changing from one compound to another and is recommended as a routine practice. 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.

It is especially suited for those compounds used for r3123 or other low pressure molding techniques. Because this test method does not contain a round-robin-based numerical precision and bias statement, it shall not be used as a referee test method in case of dispute. Best Practices for Incorporating Standards Education in the. For referee testing, all material shall be shipped and stored in moisture-barrier containers.
We have no amendments or corrections for this standard. The use of excessive amounts of compound will result in shorter, inconsistent spiral flows.
Data Sheet for CalCoat ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

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. Last previous edition approved in as D – 98 Therefore, the force exerted by the plunger shall be measured by some means such as an accurately calibrated direct-reading force gage or proving ring.
NOTE 4—There is considerable evidence that the test is usable over a wider range of flow lengths, but this has not yet been confirmed by interlaboratory testing. It is recommended that a pot diameter between The relationship between the amount of compound and the dimensions of the transfer pot is critical in obtaining meaningful, reproducible spiral-flow values.
NOTE 3—Since the only commercially available molds are calibrated in inches, spiral-flow length will be reported in these units. Please first verify your email before subscribing to alerts. For transfer pots It involves the use of a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature and pressure with a controlled charge mass.

If the document is revised or amended, you will be notified by email. Cure the compound as recommended for easy removal. Standards Subsctiption may be the perfect solution. NOTE 2—Preliminary evidence indicates that, in many cases, reasonable correlations may be achieved between laboratories using presses with different pot diameters. This standard is not included in any packages. Several preliminary moldings shall be made with the material to be tested to purge the helical runner before beginning the test.
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. D — 09 FIG. Need more than one copy?
