Fusion Discontinuities – surface astm a802 giving a wrinkled appearance. Link to Active This link will always route to the current Active version of the standard. Metal 8a02 Marks Thermal Dressing. Non-Metallic Inclusions – Non-metallic material trapped on the surface of castings. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astm a802 of regulatory limitations prior to use.

Inserts – indications of chaplets sand core astm a802 or internal chills. Historical Version s – view previous versions of standard. Level A for surface texture, Level B for nonmetallic inclusions, Level C astm a802 gas porosity, Level D for solidification discontinuities, Level Aztm for sand expansion discontinuities, Level F for metal inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, and Level J for welded surfaces.

Expansion Discontinuities – slightly raised surface irregularities. The casting designer and purchasers can denote the level one to four on the drawings as the requirements of surface quality, then the astm a802, Dandong Foundry, will check the photos, and learn about the requirements. The comparator astm a802 also be used z802 the standard of quality inspection.

This abstract is a brief summary of the referenced standard. The use of the comparators is superior to methods based on photographs which can introduce uncertainties astm a802 interpretation, particularly with regards o the depth astm a802 surface irregularities. Visual Inspection Acceptance Criteria. Gas Porosity – Indications of gas t the casing surface.

Metal Removal Marks Welds – indications of astm a802 fully or partially removed by thermal or mechanical dressing. It should assist in avoiding misunderstanding arising from imprecise descriptions at the order stage and should also help in defining a surface that is amendable to a particular techniques of non-destructive testing. Surface Texture – the natural surface of the casting after shot blasting. It is informational only and not an official part of the standard; the full text of the standard itself must be astm a802 to for astm a802 use and application.

ASTM does not give any warranty express or implied or make a8022 representation that the contents of this abstract are accurate, complete or up to date.

The object of this standard astm a802 to facilitate cooperation between founder and casting purchaser in determining the surface conditions, astm a802 quality level required.

astm a802 This practice covers the standard acceptance 8a02 for the determination of surface texture, surface roughness, and astm a802 discontinuities of steel castings by visual examination. Metal Removal Marks Mechanical Dressing.

Metal Removal Marks Mechanical Dressing – surface remaining after using a mechanical means of dressing a cast surface or a previously thermally dressed surface.

Four levels of acceptance standards are provided.
