馆藏竹木器文物含水率快速测定

1范围

本文件描述了馆藏竹木器文物含水率的快速测定方法。

本文件适用于采用电容法原理，对经过干燥处理后含水率已与保存环境达成平衡的馆藏竹木器文物

含水率进行的简易、快速测定。

2规范性引用文件

下列文件中的内容通过文中的规范性引用而构成本文件必不可少的条款。其中，注日期的引用文

件，仅该日期对应的版本适用于本文件；不注日期的引用文件，其最新版本（包括所有的修改单）适用

于本文件。

3术语和定义

下列术语和定义适用于本文件。

3.1

馆藏竹木器文物bambooandwoodcollection

博物馆、图书馆等收藏单位收藏的竹质、木质文物和其他文物中竹质、木质构件的总称。

3.2

含水率moisturecontent

馆藏竹木器文物（3.1）所含水分质量与全干质量的百分比。

4原理

竹质、木质类材料含水率的变化会引起其电容介电常数的改变，通过测量电容介电常数，可间接测

定其含水率。

5试验条件

快速测定含水率应符合下列条件：

a）温度：15℃～35℃；

b）相对湿度：25%～90%；

c）大气压力：80kPa～106kPa。

6仪器设备

馆藏竹木器文物含水率快速测定的仪器应符合以下要求：

a）准确度等级不低于JJG986—2004中3.1规定的2.0级；
