ASTM A Surface Acceptance Standard for Steel Castings – Mookambika Metallurgical Solutions

It should assist in avoiding misunderstanding arising from imprecise descriptions at the order stage and should also help in defining a qstm that is amendable to a particular techniques of astm a802 testing. Fusion Discontinuities – surface irregularities giving a wrinkled appearance. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm a802 limitations prior to use.

The casting designer and purchasers can denote the level one to four on the drawings as the requirements of surface astm a802, then the founder, Dandong Foundry, will check the photos, and learn about the requirements. Four levels of acceptance standards are 8a02. Astm a802 Version s – view previous versions of standard.

The object of this standard is to facilitate cooperation between founder and casting purchaser in determining the surface conditions, and quality level required. It is informational only and not an official part of the standard; the full text astm a802 the standard itself x802 be referred to astm a802 its use and application.

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

This abstract is a brief summary of the referenced standard. Visual Inspection Acceptance Criteria.

Zstm comparator can also be used as the standard of quality inspection. Metal Removal Marks Mechanical Dressing. Surface Texture – the natural surface of the casting after shot blasting. Link to Astm a802 This link will always route to the current Active version of the standard. Gas Porosity – Indications of gas t astm a802 casing surface.

Metal Removal Marks Welds – indications of welds fully or partially removed by thermal or mechanical dressing. Metal Removal Marks Thermal Dressing. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Asgm 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 metal inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, and Level J for welded astm a802. The use of the comparators astm a802 superior to methods based on photographs which astm a802 introduce uncertainties concerning interpretation, particularly with regards o the depth of surface irregularities.

Non-Metallic Inclusions – Non-metallic material aztm on the surface of castings. Expansion Discontinuities – slightly raised surface irregularities. This practice covers the standard astm a802 criteria for the determination of surface texture, surface roughness, and surface discontinuities of steel castings astm a802 visual examination.

Inserts – indications of chaplets sand core supports or internal chills.
