GB/T 1541-2013 "Paper and board—Determination of dust content" specifies the method for determining the dust content of paper and board, applicable to various types of paper and board. The specimen is laid flat on a dust content testing table, and dust particles of different sizes are identified and counted under standard light using a magnifying glass. The counts are classified and tallied according to specified categories. The standard clarifies the requirements for specimen sampling, cutting dimensions, and dust particle area classification criteria. The test area for each specimen must not be less than 0.0625 m², and the results are expressed as the number of dust particles per square meter for each category, providing a basis for evaluating the cleanliness of paper.
