Difference between word needs and word expectations

Although the ISO 45001:2015 standard does not define the terms ‘needs’ and ‘expectations’ when it talks about the needs and expectations of interested parties, it is helpful to think of them in this way. Needs are those things that interested parties have clearly stated or written down, such as a health & safety law that you need to meet or a safety requirement in a collective agreement with the workers union. Expectations are the unwritten things that the interested parties reasonable assume you will do, such as accurate tracking of information to meet those laws or timely addressing safety concerns when they are raised.

You can learn more about interested parties in this article: Determining interested parties according to ISO 45001, https://advisera.com/45001academy/blog/2018/03/14/determining-interested-parties-according-to-iso-45001/

thanks for the comment Mr. Mark, so  can i write like this  :

Interested Party Name :  National Records and Archive Authority
 Needs :   Comply with RD 60/2007 (records and archives law)
Expectation : Follow National Records and Archive Authority Regulations / guidelines.

As, some time inside the law , there are articles and sections , as well as in the articles  there are requirements e.g sending informations, reports and data. so , it will be enogh if i write like statement above "  Comply with RD 60/2007 (records and archives law) " or shall i write the details of the laws  liske sending report , information 

What you have is good, as long as it gives you enough information going forward.

One interesting thing about this clause fo the standard is that it does not require doucmented information, so any documentation you keep on the needs and expectations of interested parties is in addition to what the standard requires, so just make sure that it has enough informaiton for you and yoru managmeent team to be able to assess that they understand the need as they review it in an ongoing basis.
