Very often quality is not a consideration of the project charter. This is due to the fact that the project sponsor usually doesn't know what the project solution is at that point. If there is a rough idea of what is expected of the final deliverable, then the project sponsor should at least consider how "testable" the final product is and provide some guidance through the budget and resources. Certain "mission critical" projects (lives are at stake) may have a better idea (e.g. building a new medical instrument, new space program) of quality requirements, but they will be stated at a very high level (e.g. safe, no lives lost, etc.).
