描述

For the determination of the water absorption of sized paper and board, including corrugated fibreboard, under standard conditions. It may not be suitable for paper of less than 50 g/m? or for porous papers such as newsprint or un-sized papers such as blotting paper or other papers having a relatively

的大小的紙和紙板吸水率的測定，包括瓦楞紙板，在標(biāo)準(zhǔn)條件下。它可能不適用于紙張小于50克/米?或紙張如新聞紙或聯(lián)合國大小的紙等吸水紙或其他文件有一個相對

high water absorption. A test piece is weighed immediately before and immediately after exposure of one surface to the water for a specified time, followed by blotting. The result of the increase in mass is expressed in grams per square metre (g/m2). The standard model has a test area of 100 cm?. The model NV50 is delivered with 100, 50 and 10 cm? area.

高吸水性。試件稱重之前和一個表面的一個特定的時間與水接觸后立即，其次是印跡。在質(zhì)量的增加，其結(jié)果是克每平方米表示（克/平方米）。標(biāo)準(zhǔn)模型有100厘米?試驗區(qū)。該模型nv50交付100，50和10厘米?地區(qū)。

Test description

測試描述

100 ml ? 5 ml of water, or proportionately less for a smaller test area, are poured into the cylinder, thus providing a head of 10 mm. The sample is placed on top and the lid closed. As the cylinder is turned over the timer starts automatically. The exposure time is selected according to the degree of water absorption of the paper and board. If, for example, a test time of 60 s has been selected, the cylinder is turned back after 50 s. The sample is quickly unclamped and placed (test face up) on a sheet of dry blotting paper on the couching table. 60 s after commencement of the test a second sheet of blotting paper is placed on top of the test piece and the excess water removed by pushing the couching table fully in under the couch roll and pulling it back again.

100毫升?5毫升的水，或相對少的一個較小的試驗區(qū)，倒入缸，從而提供了一頭10毫米。樣品被放置在頂部和蓋子關(guān)閉。當(dāng)筒體翻轉(zhuǎn)計時器自動啟動。曝光時間是根據(jù)對紙和紙板吸水度選擇。如果，例如，測試時間為60 s已被選定，氣缸轉(zhuǎn)身后50秒。樣品快速松開并放置（測試面）上貼一張吸墨紙上干。60秒后，測試的二張吸墨紙開始被放置在頂部的試件和多余的水推撥表完全在伏輥和拉回來取下。
