Where can information about gasket material for orifice plates be found?

The correct choice identifies that information about gasket material for orifice plates can be found in MIL-R-1149. This standard specifically addresses the requirements for rubber materials, which are commonly used in gaskets for various applications, including orifice plates. The specifications in this document ensure that the gasket materials meet necessary performance and safety criteria, making it essential for selecting the right type of gasket material for fluid containment and proper sealing in piping systems.

The other standards mentioned do not primarily focus on gasket materials for orifice plates. ASTM D-2000 pertains to rubber properties and definitions specifically but may not provide the comprehensive guidelines specifically targeted at orifice plate gaskets. ISO 9001 is a quality management standard that outlines general requirements for quality management systems but does not deal specifically with materials used in engineering applications. ANSI B18.2.1 outlines dimensions for bolts and screws, which is unrelated to gasket materials. Thus, MIL-R-1149 is the relevant document for understanding the appropriate gasket materials for this specific application.
