Standards came about when industry professionals came together and decided on best practice on how to design or manufacturer something.  This way, when you design, buy or install something that complies with a certain Standard you know that it meets the quality and principles set out by the makers of the standard.  

Some companies may want to not only be told something meets or exceeds a certain standard but many times they want it to be taken a step further and have a third party (another independent company) certify that it is.  In other places there may be laws in place requiring this as well 

Over time, many standards were developed by many different associations in many different countries.  Quite a few of these standards have parts that overlap as they expanded to include more and more facets of a particular discipline or design.
