Micrographics. First generation silver-gelatin microforms of source documents. Density specifications and method of measurement Ingestion-build-47553 BS EN 12351 does not1 Scope This International Standard specifies a method for measuring densities of first generation silver gelatin microforms. It specifies density values for different qualities of documents. It applies to source document negative appearing microforms. It does not apply to microforms for technical drawings which are dealt with in ISO 3272 2, or to diazo and vesicular films which are the subject of ISO 8126, or to COM microforms which are dealt with in
