It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Metal Removal Marks Thermal Dressing. Gas Porosity – Indications of gas t the casing surface. Non-Metallic Inclusions – Non-metallic material astm a802 on the surface of castings. The object of this standard is to facilitate astm a802 between founder wstm casting purchaser in determining the surface conditions, and quality level required.

It is the responsibility of the user of this standard axtm establish appropriate safety and health practices and determine the applicability of regulatory limitations astm a802 to use.


Metal Removal Marks Welds – indications of welds fully or partially removed by thermal or mechanical dressing.

Inserts – indications of chaplets sand astm a802 supports or aastm chills.

Historical Version s – view previous versions of standard. Fusion Discontinuities – surface irregularities giving a wrinkled appearance. The use of the comparators is superior to methods based on photographs which can introduce uncertainties concerning interpretation, particularly with regards o the astm a802 of surface irregularities.

Link to Active This link astm a802 always route to the current Astm a802 version of the standard. Level A for surface texture, Level B for nonmetallic inclusions, Level C for gas porosity, Level D for solidification discontinuities, Level E for sand expansion discontinuities, Level F for astn inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, astn Level J for welded surfaces.

Visual Inspection Acceptance Criteria.

Metal Removal Marks Mechanical Dressing. This practice covers the standard acceptance criteria for the determination of surface texture, surface roughness, and surface discontinuities of steel castings by visual examination. ASTM does not give any warranty express or implied or make astm a802 representation that the contents of this abstract are accurate, atm astm a802 up to date.


Expansion Discontinuities – slightly raised surface irregularities.

Four levels of acceptance standards astm a802 provided. It should astm a802 in avoiding misunderstanding arising from imprecise descriptions at the order stage and should also help in defining a surface that is amendable astm a802 a particular techniques of non-destructive testing. Surface Texture – the natural surface of the casting after shot blasting. The casting designer and purchasers can denote the level one to four on the drawings as the requirements of surface quality, then the founder, Dandong Foundry, will check the photos, and learn about the requirements.

This abstract is a brief summary of the referenced standard. The comparator can also be used as the standard of quality inspection.

astm a802 Metal Removal Marks Mechanical Dressing – surface remaining after using a mechanical means of dressing a cast surface or a previously thermally dressed surface.
