It should assist in avoiding misunderstanding arising from imprecise descriptions at the order stage and should also help in defining a surface that is astm a802 to a particular techniques astm a802 non-destructive testing. Fusion Discontinuities – surface irregularities giving a wrinkled appearance.
The casting designer and purchasers can denote the asgm one to four on the drawings as the requirements of surface quality, then the founder, Dandong Foundry, will check astm a802 photos, and learn about the requirements. Historical Version s – view previous versions of standard. ASTM does not give any warranty express or implied or make any representation that the contents astm a802 this abstract are accurate, complete or atm to date.
Gas Porosity – Indications of gas t the casing surface.
Astm a802 Removal Marks Mechanical Dressing. The comparator can also be used as the standard of quality inspection. Expansion Discontinuities – slightly raised surface irregularities. This practice covers the standard acceptance criteria for the determination of surface texture, surface roughness, and surface discontinuities of steel castings by visual examination.
Visual Inspection Acceptance Criteria. Metal Removal Marks Mechanical Astm a802 – surface remaining after using a mechanical means of dressing a cast surface or a previously w802 dressed surface.
This abstract is a brief summary astm a802 the referenced standard. Link to Active This link will always route to the current Active version of the standard. Metal Removal Marks Thermal Dressing.

Four levels of acceptance standards are provided. Level A for surface texture, Level B for nonmetallic inclusions, Level C for gas porosity, Astm a802 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 Astm a802 for adtm surfaces.
Non-Metallic Inclusions – Non-metallic material trapped on the surface of castings. Metal Removal Marks Satm – indications of welds fully or partially removed by thermal or mechanical dressing. astm a802
Astm a802 object of this standard is to facilitate cooperation between founder and casting purchaser in astm a802 the surface conditions, and quality level required. Surface Texture – the natural surface of the casting after shot blasting.
Inserts – indications of astm a802 sand core supports or internal chills. The use of the comparators is superior to methods based on photographs which can introduce uncertainties concerning interpretation, sstm with regards o the depth of surface irregularities. 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. It is informational only and not an official astm a802 of the standard; the full text a8002 the standard itself must be referred to for its use aa802 application.
