pH of aqueous extracts in cold or hot water extractions of paper, board or pulp

With this test, the pH of water extraction (hot or cold) from a paper, board, or pulp sample is measured. The extraction is performed with deionized water, so the results may vary slightly from samples that are taken in mill process conditions.
