Standards are seldom available without cost. You can however generally search for free at the websites of standards developers and vendors.
From OMB Circular A-119: "The term "standard," or "technical standard" includes all of the following:
* Common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices.
* The definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength."
Take advantage of these free resources to find the standards you need. If you want to obtain a copy of a standard be sure to get the title and number of the standard.
