You can try contacting Apple corporate headquarters:
1 Infinite Loop
Cupertino, CA 95014
But don't hold your breath. Apple is a very closed mouth company, they don't usually discuss things like this with the public. But it's worth a shot, what can they do besides tell you no or ignore you.

...Also, clicking on the various HR job titles HERE may be helpful. And you could ask your question of THIS guy who runs a site about Apple Stores. And this quote from Steve Jobs may give some insights into Apple's view of HR:
"In the field that I'm in the difference between the best person and the worst person is about a hundred to one or more. The difference between a good software person and a great software person is fifty to one, twenty-five to fifty to one, huge dynamic range. Therefore, I have found, not just in software, but in everything I've done it really pays to go after the best people in the world. It's painful when you have some people who are not the best people in the world and you have to get rid of them; but I found that my job has sometimes exactly been that to get rid of some people who didn't measure up and I've always tried to do it in a humane way. But nonetheless it has to be done and it is never fun." (Source)
Sara ~ Apple's mission statement is HERE. But the following statement from Apple's now-CEO Tim Cook during a quarterly earnings conference call on 21 January 2009 may give more insight:
"There is an extraordinary breadth and depth and tenure among the Apple executive team, and these executives lead over 35,000 employees that I would call "all wicked smart". And that's in all areas of the company, from engineering to marketing to operations and sales and all the rest. And the values of our company are extremely well entrenched.
We believe that we're on the face of the Earth to make great products, and that's not changing. We're constantly focusing on innovating. We believe in the simple, not the complex. We believe that we need to own and control the primary technologies behind the products we make, and participate only in markets where we can make a significant contribution.
We believe in saying no to thousands of projects so that we can really focus on the few that are truly important and meaningful to us. We believe in deep collaboration and cross-pollination of our groups, which allow us to innovate in a way that others cannot.
And frankly, we don't settle for anything less than excellence in every group in the company, and we have the self-honesty to admit when we're wrong and the courage to change. And I think, regardless of who is in what job, those values are so embedded in this company that Apple will do extremely well."
Thank you Alancito, as I always love reading this stuff, and I thought the last inquiry was perhaps directed my way.
Studying Apple should be a pure joy. If you can do that within the confines of academia, then fantastic. Otherwise enjoy it for what it is when you aren't on the university clock. I certainly would expect that Apple has ISO certifications, but writing about them doesn't really deliver the oomph delivered by the statement above.
Have you spoken with your campus library's Business Librarian (or a General Reference Librarian at your campus's main library or library website)? There is a plethora of subscription online databases for business, and your tuition and fees cover access to the ones for which your institution has contracted. Some hardcopy business encyclopedias and other sources might have to be consulted on site. Between that historical and background information and any corporate information available to current job applicants, you'd have a starting point for a formal inquiry to the company. Your campus's jobs center probably would also have hardcopy (and maybe online) collections of info for its students.
