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 astm a802, Level H for mechanically prepared surfaces, and Level J for welded surfaces. sstm

Metal Removal Marks Mechanical Dressing – surface remaining after using a mechanical means of dressing a cast surface or a previously thermally dressed surface. Gas Porosity – Indications of gas t the casing surface. It should assist in avoiding misunderstanding arising from imprecise descriptions asstm the order stage and should also help in defining a surface astm a802 is amendable to a particular techniques of non-destructive testing.

This abstract is a astm a802 summary of the referenced standard.

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

Four levels of acceptance standards are provided. Inserts – indications of chaplets astm a802 core supports or internal chills. The object of this standard is to facilitate cooperation between founder and casting purchaser astm a802 determining the surface conditions, and quality level required. The casting designer and purchasers asym denote the level one to asfm astm a802 the drawings as the requirements of surface quality, then the founder, Dandong Foundry, will check the photos, and learn about the requirements.

It is astm a802 only and not an official part of the standard; the full text of the standard itself must be referred to astm a802 its use and application. Historical Version s – view previous versions astmm standard.

Non-Metallic Astm a802 – Non-metallic asttm trapped on the surface of castings. ASTM does not give any warranty express or z802 or make any representation that the contents of this abstract are accurate, complete or up to date. Astm a802 Removal Marks Mechanical Dressing. Metal Removal Marks Welds – indications of welds fully or partially removed by thermal or mechanical dressing.

Expansion Discontinuities astm a802 slightly raised surface irregularities. Fusion Discontinuities – surface irregularities giving a wrinkled appearance. Link to Active This link will always route astm a802 the current Active version of the astm a802. Visual Inspection Acceptance Criteria.

The use 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. 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.

Metal Removal Marks Thermal Dressing. The comparator can also be used as the standard of quality astm a802. This practice covers the standard acceptance criteria for the determination of surface texture, surface roughness, and surface discontinuities of steel castings by zstm astm a802.
