The Prince2 Project Product template lists Quality Expectations separately to Acceptance Criteria.
What is the difference is between these two items? They seem like the same type of requirement to me.

Acceptance criteria defines when a project product is "done" while quality criteria (they don't use the term "Quality Expectations" in the glossary or index of the text) defines how you measure quality of a completed product and what specification has to be met.
From the PRINCE2 text (2009 edition):
Acceptance Criteria A prioritized list of criteria that the project product must meet before the customer will accept it, i.e. measurable definitions of the attributes required fro the set of products to be acceptable to key stakeholders
and
Quality Criteria A description of the quality specification that the product must meet, and the quality measurements that will be applied by those inspecting the finished product.
The question asks for the difference between (customer's) quality expectations and acceptance critera in the Project Product (Description).
(Words between brackets added to show the correct PRINCE2 terminology.)
The definition of acceptance criteria is given in the first answer. The official PRINCE2 manual gives also the definition of the other element:
customer's quality expectations — A statement about the quality expected from the project product, captured in the Project Product Description.
(see the PRINCE2 2009 Glossary of Terms)
Let's take a simple example to clarify the distinction: you go to a local car dealer in order to buy a new car. The salesman walks up to you and asks what type of car you are looking for.
