GB/T 9966.3-2001Test methods for natural facing stones -- Part 3: Test methods for bulk density, true density, true porosity and water absorption (English PDF)

Foreword

The test methods of water absorption, bulk density in this Standard equivalently adopt

American ASTM C97.1996 Test Methods of Water Absorption, Bulk Density for

Dimension Stone.

This Standard modified GB/T 9966.3-1988 Test Methods for Natural Facing Stones –

Test Methods for Bulk Density, Ture Density, Ture Porosity and Water Absorption; the

major technical contents were consistent with the original standard.

This Standard replaced GB/T 9966.3-1988 since the date of implementation.

This Standard was proposed by State Construction Materials Industry Association.

This Standard shall be under the jurisdiction of Synthetic Crystals Research Institute

of State Construction Materials Industry Association.
