1. Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2 ...
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services.

American steel grades : AISI/SAE steel grades standard; British Standards; International Organization for Standardization ISO/TS 4949:2016; European standards – EN 10027
A word search, word find, word seek, word sleuth or mystery word puzzle is a word game that consists of the letters of words placed in a grid, which usually has a rectangular or square shape. The objective of this puzzle is to find and mark all the words hidden inside the box.
ABS steels include many grades in ordinary-strength and two levels of higher-strength specifications. All of these steels have been engineered to be optimal long-lived shipbuilding steels. ABS does permit the use of other steels in shipbuilding, but discourages it, and requires more detailed engineering analysis.
The stress intensity factor at the crack tip of a compact tension specimen is [4] = [() / / + / / + /] where is the applied load, is the thickness of the specimen, is the crack length, and is the effective width of the specimen being the distance between the centreline of the holes and the backface of the coupon.
A Publicly Available Specification or PAS is a standardization document that closely resembles a formal standard in structure and format but which has a different development model. [1] The objective of a Publicly Available Specification is to speed up standardization. PASs are often produced in response to an urgent market need. [2]
The word specification is broadly defined as "to state explicitly or in detail" or "to be specific". A requirement specification is a documented requirement , or set of documented requirements, to be satisfied by a given material, design, product, service, etc. [ 1 ] It is a common early part of engineering design and product development ...
