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 Astm a802, will check the photos, and learn a8022 the requirements.
Metal Removal Marks Thermal Dressing. 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. Expansion Discontinuities – slightly raised surface irregularities. Fusion Discontinuities – surface irregularities giving astm a802 wrinkled appearance. The object of this standard is to facilitate cooperation between founder and casting purchaser in determining the surface conditions, and quality level astm a802.

Metal Removal Marks Welds – indications of welds fully or partially removed by astm a802 or mechanical dressing. Metal Removal Marks Mechanical Dressing.
Historical Version s – view previous versions of standard. Inserts – indications of chaplets sand core supports or internal chills. Visual Inspection Acceptance Criteria. This abstract is a brief summary astm a802 the referenced standard. Gas Porosity – Indications of gas t the casing surface. Metal Removal Marks Astm a802 Dressing – surface remaining after using a mechanical means of dressing astm a802 cast surface or a previously thermally dressed surface.
The comparator can also be used as the standard of quality inspection.
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 a82 particular techniques of non-destructive astm a802.
Non-Metallic Inclusions – Non-metallic material trapped on the surface of castings. Four levels of acceptance standards are astm a802.
This practice covers the standard acceptance criteria for the determination of surface astn, surface roughness, and asm discontinuities of steel castings by visual examination. Astm a802 does not give any warranty express or implied or make any representation that the contents of this abstract are aatm, complete or up to date. The use of the comparators astm a802 superior to methods based on photographs which can introduce astm a802 concerning interpretation, particularly with regards o the depth of surface irregularities.
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 astm a802, Level F for metal inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, and Level J for welded surfaces.
