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.

Inserts – indications of chaplets astm a802 core supports or internal chills. This abstract is a brief summary of the astm a802 standard.

Gas Porosity – Indications of gas t the casing surface. 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 astm a802 metal inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, and Level J for astm a802 surfaces. Expansion Discontinuities – slightly raised surface irregularities.

Metal Removal Marks Welds – indications of welds astm a802 or partially removed by thermal ast, mechanical dressing.

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 a particular techniques of non-destructive testing.

Visual Inspection Acceptance Criteria. Metal Removal Marks Astm a802 Dressing – surface remaining after using a mechanical means of dressing a cast surface or a previously thermally dressed surface.

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. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or astm a802 to date.

Four levels of acceptance standards are provided. Astm a802 comparator can astm a802 be used as the standard of quality inspection.

Metal Removal Marks Mechanical Dressing. Non-Metallic Inclusions – Non-metallic material trapped on the surface astm a802 castings. The casting designer and purchasers astm a802 denote the level one to four on the drawings as the requirements of surface quality, then the founder, Dandong Foundry, will check the photos, and learn about the requirements.

It is informational only and not an official part of the axtm the full text of the standard itself must be referred to for its astm a802 and application. Fusion Discontinuities – surface irregularities giving a wrinkled appearance.

This practice covers astm a802 standard acceptance criteria for the determination of surface texture, surface roughness, astm a802 surface discontinuities of steel castings by visual examination.

The object of this standard is to facilitate cooperation between founder and casting purchaser in determining the surface conditions, and quality level required.
