What is ISO 1762 on Paper, board, pulps, and cellulose nanomaterials about?
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.
Who is ISO 1762 on Paper, board, pulps, and cellulose nanomaterials for?
ISO 1762 on paper, board, pulps, and cellulose nanomaterials is useful for:
- Manufacturers and suppliers of paper and boards
- Paper mills, pulp, and boards industry
- Designers of paper and boards
- Test /service providers for paper and boards
Why should you use ISO 1762 on Paper, board, pulps, and cellulose nanomaterials?
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.
What’s changed since the last update?
BS ISO 1762:2019 supersedes BS ISO 1762:2015, which is withdrawn. BS ISO 1762:2019 includes the following changes:
- Scope revised to cover cellulose nanomaterials instead of only paper, board, and pulps
- A definition of cellulose nanomaterial, along with additional instructions for sampling, sample preparation, and incineration for cellulose nanomaterials have been incorporated
- Additional instructions are given on how to express results when a sample has a low ash content
