ASTM standards are categorized by a prefix letter followed by a unique number:
This is a unique consumer safety standard. It requires that all art supplies (paint, markers, clay) be evaluated for chronic health hazards. If a product meets D4236, it will carry the label "Conforms to ASTM D4236" and include a phone number for health information. This standard removed toxic heavy metals from children's paints. norma astm
The is the silent infrastructure of the modern material world. When you drive over a bridge, use an extension cord, or give a child a crayon, you are trusting that the materials used were designed, tested, and validated against an ASTM standard. ASTM standards are categorized by a prefix letter

They ensure that a bolt manufactured in Germany fits a nut manufactured in the United States, or that the steel used in a bridge in Japan meets the same safety requirements as steel used in a bridge in Brazil.
In the world of manufacturing, engineering, and construction, the phrase "It meets ASTM specs" carries significant weight. (where "Norma" is the Spanish, Italian, Romanian, and Slavic term for "standard") refers to the vast collection of technical standards developed by ASTM International (formerly known as the American Society for Testing and Materials).
