ISO 1762 is an international standard that covers guidelines for paper, board, pulps, and cellulose nanomaterials.
ISO 1762 describes the determination of the residue (ash content) on the ignition of paper, board, pulps, and cellulose nanomaterials at 525 °C. It is applicable to all types of paper, board, pulp, and cellulose nanomaterial samples.
ISO 1762 provides measurement procedures to obtain a measurement precision of 0.01 % or better for residue (ash content) on ignition at 525 °C.
ISO 1762 specifies technicalities terms, definitions, test principle, apparatus for the test, sampling and preparation of test specimen, test procedure, expression of results, etc. for determination of residue (ash content) on ignition at 525 °C.
ISO 1762 on paper, board, pulps, and cellulose nanomaterials is useful for:
The magnitude of the residue (ash content) on ignition at a given temperature is related to the content of mineral constituents in the paper, board, or other products.
ISO 1762 gives you test procedures for determining the ash content (residue) in the paper, board, pulps, and cellulose nanomaterials. This helps you understand and calculate the amount of added mineral constituents from the result.
ISO 1762 describes an ignition procedure, that can be used as a preliminary step when determining particular mineral constituents. This enables you to use the result value as a screening test for checking the overall quality of a product, i. e. paper, board, pulp, and cellulose nanomaterials.
