I suspect it may have been "non-standard" referring to the use of a non- FLOS (Flight Level Orientation Scheme- i.e. single alternate, double alternate etc) level initially.
We often (didn't you OTB??) use the phrase e.g. "climb to non-standard F410" to highlight to the pilot that they will be operating contrary to the standard FLOS - not that you care probably - but just to raise your situational awareness.
