Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 1966-1996 "Test method for apparent porosity and bulk density of porous ceramics" and is consistent with GB/T 1966-1996.
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
Added the terms and definitions of porous ceramics (see 3.1); -
The accuracy of the test weighing device has been changed (see 4.2, Chapter 1 of the.1996 edition); -
The sample preparation requirements have been changed (see 5.1, Chapter 6 and Chapter 7 of the.1996 edition); -
The requirements for sample status have been changed (see 5.1, Chapter 8, Chapter 9, and Chapter 10 of the.1996 edition); -
The number of test samples has been changed (see 5.3, Chapter 4 of the.1996 edition); -
Added test conditions (see 6.1); -
The test vacuum degree, evacuation time, and pressure holding time of the vacuum method have been changed, and the vacuum degree has been changed from "less than 10 mmHg" to "less than
2500 Pa”, the suction time was changed from “ten minutes” to “15 min”, and the pressure holding time was changed from “when no bubbles appear”
"Can be stopped" is changed to "Evacuate for 30 min" (see 6.3.2, Chapter 12 of the.1996 edition);
Added the preparation of soaked towels (see 6.5); -
Added the determination of immersion liquid density (see 6.7); -
Changed test report requirements (see Chapter 8, Chapter 7 of the.1996 edition). -
