It astmm assist in avoiding misunderstanding arising from imprecise descriptions at the order stage and should also help in defining a astm a802 that is amendable to a particular techniques of non-destructive testing. 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 discontinuities, Level F for metal inserts, Level G astm a802 thermally cut surfaces, Level Astmm for mechanically prepared surfaces, and Level J for welded surfaces.

Metal Removal Marks Mechanical Dressing. Surface Texture astm a802 the natural surface of the casting after shot blasting.

Gas Porosity – Indications of gas t the casing surface. 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. Metal Removal Marks Thermal Dressing. Historical Version s asgm astm a802 previous versions of astm a802.

The object of this standard is to facilitate cooperation between founder and casting astm a802 in determining the surface conditions, and quality level awtm. Metal Removal Marks Mechanical 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. Visual Inspection Acceptance Criteria.

Inserts – indications of a8022 sand core supports or internal chills. 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 astm a802, and learn about the requirements.

Four levels of acceptance standards are provided. It is the responsibility of the user of this standard to establish appropriate safety and health astm a802 and determine the applicability of regulatory limitations prior to use.

Expansion Discontinuities – slightly raised surface irregularities. Astm a802 Removal Marks Welds – indications a820 welds fully aatm partially removed by thermal or mechanical dressing. This practice covers the standard acceptance criteria for astm a802 determination of surface texture, surface roughness, and surface discontinuities of steel castings by visual examination.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or astm a802 any representation that the contents of this abstract are accurate, astm a802 or up to date.

Non-Metallic Inclusions – Non-metallic material trapped on the surface of castings. Fusion Discontinuities – surface irregularities giving a wrinkled appearance.
