Precision and Bias surface with the roughness on the comparator segments. View Full Details and Buy. Gustavo Eduardo Vargas Raynholds. Link to Active This link will always route to the current Active version of the standard. Work Item s - proposed revisions of this standard.
Association Connecting Electronics Industries. Therefore, differences are inevitable, particularly with deeper surface profiles, and the results may or may not fall within the specified range for one of the two methods.
These test methods cover the description of techniques for measuring the profile of abrasive blast cleaned surfaces in the laboratory, field, or in the fabricating shop. The base of the instrument rests on the peaks of the surface profile while the cone-shaped point projects into the valley.
Synapse Information Resources, Inc. Segundo Fernandez Perfecto. Today, Method B and Method C are the most commonly used, so that is what we will be focusing on. Typically, the higher the coating thickness the greater the surface profile depth.
Standards for Measurement of Surface Profile There are currently four primary standards for measurement of surface profile in steel surfaces. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The base of the instrument micrometer. The instruments described are readily portable and sufficiently sturdy for use in the field.
Popular Standards Bundles. Addison-Wesley Publishing Co.
This method can be used to measure the surface profile depth that is created by abrasive blast cleaning or impact-type power tools. International Organization for Standardization. American Petroleum Institute. The creation of this peak-valley pattern in the surface effectively increases the surface area, providing an anchor for the coating system.

American Welding Society, Inc. Standards Australia International, mechquest hack Ltd. World Scientific Publishing Co.
Dunedin Academic Press Ltd. The comparator areas are used with or without mean determined. At each location make three readings and loose surface interference material, dirt, dust, and abrasive determine the mean. Prices subject to change without notice. American Industrial Hygiene Assn.
British Standards Institution. This is done because of evidence that coatings performance in any one small area is primarily influenced by the highest surface features in that area and not by the average roughness. When the abrasive impacts the surface, it cuts into the surface angular abrasives or peens the surface round abrasives and creates a series of peaks and valleys in the surface. Item is contained in these product bundles.
Subtract the thickness of the noncompressible plastic measured using a spring-loaded micrometer. The values given in parentheses are for information only. Springer-Verlag New York, Inc. Adjust the instrument to zero.
Aerospace Industries Association. This can be discussed and agreed upon at the pre-construction conference.
There are For this reason, surface profile should be measured prior to additional techniques suitable for laboratory use not covered by coating application to ensure that it meets that specified. There are additional techniques suitable for laboratory use not covered by these test methods. Then determine the mean for all the residue. International Electrotechnical Commission.
Deutsches Institut fur Normung E. Then determine the mean for all the replicates, obtained by operators in different laboratories locations and report it as the profile of the surface.
