Teachers’ Standards GOV.UK. Minimum Service Delivery Standards (MSDS): MSDS are defined as “minimum level of services, which the patients and service users have a right to expect”. MSDS include minimum package of services, standards of care (level specific) and mandatory requirements/system specifications that must be complied with and, A primary standard in metrology is a standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards. Primary standards are defined via other quantities like length, mass and time. Primary standards are used to calibrate other standards referred to as working standards. See Hierarchy of Standards.
