If you are looking for a standard published by a major standards developing organization (SDO), go directly to the tab for that organization, where you will find links and instructions for locating and acquiring their standards.
If the standard you seek is not published by one of the major SDOs (or you are unsure which organization is responsible), the Other Standards & Tools tab contains links to several global search engines which may help locate the standard.
standard is a document that contains technical specifications or other precise
