varaklasse

I’m not finding a widely recognized definition of “varaklasse” in general reference sources. It may be a term from a specific language (for example Dutch, German, or Norwegian) or a specialized field. Could you please specify the language and the intended field or context (for example science, linguistics, art conservation, statistics, etc.)? If you can share a source or example usage, I can draft a concise, neutral wiki-style article under 300 words tailored to that context.
