TAPPI/ANSI T 410 om-13 provides a standardized procedure for measuring the grammage of paper and paperboard by determining specimen area and mass. The method covers required apparatus, calibration of weighing and cutting devices, sampling, conditioning, test procedures, calculations, unit conversions, reporting requirements, and precision information. Results are expressed in grams per square meter and may also be converted to customary ream-weight units.
This five-page PDF standard is intended for paper manufacturers, converters, laboratories, quality-control professionals, and other technical users who need consistent basis-weight measurements for production control, purchasing, product specifications, and conformance testing.
Application Scope: Applies to laboratory and quality-control measurement of grammage, basis weight, or mass per unit area for paper and paperboard products.
