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. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up astm a802 date. astm a802
Astm a802 Inclusions – Non-metallic material trapped on the surface of castings. 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 astm a802.
Metal Removal Marks Mechanical Dressing. Inserts – indications of chaplets sand core supports or internal chills.

The astm a802 of the comparators is superior to methods based on photographs which can introduce uncertainties concerning interpretation, particularly with regards o the depth of surface irregularities.
Surface Texture – the natural surface of the casting after shot blasting. Visual Inspection Acceptance Criteria.
Fusion Discontinuities – surface irregularities giving a wrinkled appearance. This practice covers the standard acceptance criteria for the determination of surface texture, surface roughness, and surface discontinuities astm a802 steel castings by visual examination.
It is informational only and not an official part of astm a802 standard; the full text of the standard itself must be referred to for its use and application.
Historical Version s – view previous versions of standard. This abstract is a brief summary of the referenced standard. The comparator can also be used as the standard astm a802 quality inspection. Level A for surface texture, Level B for nonmetallic inclusions, Level C for gas porosity, Level D for solidification discontinuities, Level E astm a802 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.
Four levels of acceptance standards are provided. Metal Removal Marks Welds – indications of welds 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 astm a802 techniques of non-destructive astm a802. Gas Porosity – Indications of gas t the casing surface.
Expansion Discontinuities – slightly raised ashm irregularities. Metal Removal Marks Thermal Dressing. Metal Removal Marks Mechanical Dressing – surface remaining after using a mechanical means of dressing a cast surface or a previously thermally dressed surface.

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