GB/T 17911-2006 in English

《GB/T 17911-2006耐火材料 陶瓷纤维制品试验方法》由TC193（全国耐火材料标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了耐火陶瓷纤维及制品厚度、体积密度、回弹性、加热用九线变化、导热系数、抗拉强度和渣球含量的试验方法。

1 Scope

This standard specifies test methods for the thickness, bulk density, resilience, permanent linear change on heating, thermal conductivity, tensile strength and shot content of refractory ceramic fibre products.
This standard is applicable to ceramic fibre bulk, blankets, felts, mats, boards, papers and pre-formed shapes with the exception of products delivered in a wet state.

3 Preparation of Test Pieces

The test items for products shall be determined by agreement between the parties. The size and number of test pieces shall be in accordance with those specified in Table 1.
When the material to be tested is wound, any compressed material at the extreme ends shall be excluded. A strip shall be cut perpendicular to the length across the full material width, of sufficient size for the different tests planned. When the material to be tested is not wound, sufficient number of test pieces shall be provided.
