GB/T 33002-2016Thermal insulating products for building applications -- Determination of deformation under specified compressive load and temperature conditions (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to ISO 29764.:2008 "Building insulation products in the specified compression load and temperature conditions change Shape of the determination. " and the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows.

Accuracy (accuracy and precision) of measurement methods and results - Part 2. Determination of standard measurements - GB/T 6379.2-2004 the basic method of methodological repeatability and reproducibility (ISO 5725-2.:1994, IDT) this standard is proposed by the China Building Materials Federation.

This standard is nationalized by the National Standardization Technical Committee for Thermal Insulation (SAC/TC191).

The drafting unit. Nanjing Glass Fiber Research and Design Institute Co., Ltd., Shenzhen Jintai Detection Technology Co., Ltd., the national glass fiber Dimensional product quality supervision and inspection center.

1 Scope

This standard specifies the equipment and procedures required to determine the deformation under specified compressive loads, temperatures and time conditions. This standard applies Insulation products.

3 Terms and definitions

The following terms and definitions apply to this document.

Relative deformation the reduction in the thickness of the sample under the specified compressive load is expressed as a percentage of the original thickness of the sample and its measurement direction is the compressive load direction.

4 Principle

With a predetermined compressive load acting on the sample, the relative deformation of the specimen is measured in two steps, each step having a different temperature and time Conditions.
