In the specification process for steel castings, there are three key words which should be understood. These are specifications, standards, and codes.
Specifications
A specification is a form of standard, which precisely states a set of requirements to be satisfied by the casting. Some of these requirements might be chemical composition, mechanical properties, repair procedures, or any other requirement that is necessary to develop the quality of the casting needed for its end use. Specifications for steel castings are sometimes expanded or limited by standards and codes.
Standard
A standard can be defined as a specification, test method, definition, or recommended practice that has been approved by a nationally recognized specification-writing body such as ASTM (American Society for Testing and Materials), ISO (international Organization of Standards), or SAE (Society of Automotive Engineers). A standard can be further be defined as a document which details properties, processes, dimensions, materials composition, relationships, or concepts.
Code
The word ” code ” is a term of much broader meaning than either specification or standard and can best be described as a set of rules established by a recognized authority such as the American Society of Mechanical Engineers’ (ASME), Boiler and Pressure Vessel Code or the United States of America Standards Institute’s (USASI) code for pressure Piping. In adopting the rules that make up the various codes, consideration is generally based on health, safety, and environmental protection. The code-formulating bodies, in addition to writing their rules, usually adopt ASTM material specifications either in whole or in part to become a part of the code.
ABOUT KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
