How to use standard notations for the code ?

If I am writing SRS document; What will be the correct procedure to demand from the developer to use standard notations for the code.   As a part of the development project the developer is suppose to provide complete code and tools used for its development.  In functional requirements can I write that the code should be written using Hungarian standard notations? 

Choosing an appropriate Coding Style for the software development is not related to the functional requirements of the software therefore these things are not discussed in functional requirements. But, in one way, you can say that these coding styles are related to some of the non-functional requirements of the system such as mantainibility. For example, reducing the cost of software maintenance is the most often cited reason for following coding conventions. Software programmers are highly recommended to follow these guidelines to help improve the readability of their source code and make software maintenance easier. It is up to the development team to agree upon a certain coding style to follow during the development activity.
