液体渗透性试验的标准实施规程

Standard Practice for Liquid Penetrant Testing [Replaced:AIR FORCE MIL-STD-6866 CANC NOTICE 2,AIR FORCE MIL-STD-6866 VALID NOTICE 1,AIR FORCE MIL-STD-6866]

适用范围:<p>This practice establishes the basic parameters for controlling the application of the liquid penetrant method. This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the inspector and, therefore, must be supplemented by a detailed procedure that conforms to the requirements of this practice. Specification <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?E165-HTML">E165</a> contains information to help develop detailed requirements.</p><p id="s00002">1.1 This practice establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, and nonmetal components. </p> <p class="desc"> <span class="smallcap">Note</span> 18212;This practice replaces MIL-STD-6866</p> <p id="s00003">1.2 The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance (in-service) examinations. These processes are applicable for the detection of discontinuities, such as lack of fusion, corrosion, cracks, laps, cold shuts, and porosity, that are open or connected to the surface of the component under examination.</p> <p id="s00004">1.3 Caution must be exercised in the usage of elevated temperature with components manufactured from thermoplastic materials. Also, some cleaners, penetrants, and developers can have a deleterious effect on nonmetallic materials such as plastics. Prior to examination, tests should be conducted to ensure that none of the cleaning or examination materials are harmful to the components to be examined.</p> <p id="s00005">1.4 <span class="italic"><span class="italic">Units</span>8212;</span>The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.</p> <p id="s00006">1.5 All areas of this practice may be open to agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization.</p> <p id="s00007">1.6 <span class="italic">This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. </span>
