Acording to the info supplied with the test strips, purchased this year, then the accuracy is defined in accordance with ISO 15197:2013 and so is not certified to the required standard. The note in the leaflet says that this accuracy is only valid for a limited time, but does not state what this limit is. in terms of the manufacture date. The meter performance is only to an earlier version of this standard (2003) according to same leaflet, so the meter has not been recently re-qualified. The SD leaflet was last updated in 2014, so will not show any data to the required 2015 (or even 2016/17) standards.
