Причина отмены This test method covers the determination of the mass per unit area of paper and paperboard.

Значение и использование

4.1 Most paper is bought and sold in accordance with its mass per unit area, and therefore has great significance both to the consumer and the producer in defining price. Also, the values of many physical properties such as bursting strength, thickness, and bulk are interpreted and specified with regard to the particular mass per unit area involved.
