There is no need to base that comparison on a well-defined certified value and uncertainty of a CRM. The advantages in using CRMs are that the user has the 

9/22 · While Reference Materials do not give the same level of accuracy as Certified Reference Materials, their advantage is that they are significantly easier to produce. They are still compliant with ISO requirements and for less exacting requirements on traceability, they can offer an excellent cost-effective alternative to Certified Reference Materials.

NOTE 2 Procedures for the production and certification of certified reference materials are given, e.g. in ISO Guide 34 and ISO Guide 35. NOTE 3 In this definition, "uncertainty" covers both 'measurement uncertainty' and 'uncertainty associated with the value of a nominal property ', such as for identity and sequence.
