Here are reliable places from which to buy standards, if you can't get them any other way

1. Look at the web site of the particular organization whose standard you want. You will usually have to buy the standard, but there is other good information. For example, ISO's online FAQ is extremely helpful. It includes answers to common questions, including the list of products, services, and the many varied things for which there are standards.

   The web site is a little frustrating, but you can search their catalog for standards from many different sources.
   
   
3. Techstreet in Ann Arbor, MI
   
   Use their online database to search for more than 300,000 industry codes and standards from 350 of the world's leading standards developing organizations. Areas covered include aerospace, architecture/engineering/construction, boilers and pressure vessels, electronics, energy and petrochemical, food and beverage, information technology, medical and pharmaceutical, and water and wastewater, among others.
   
   The customer service FAQ page mostly concerns how to pay them and how much it costs to have standards shipped to you.
