GB/T 24328.5-2009Tissue paper and tissue products -- Part 5: Determination of grammage (English PDF)

Foreword

GB/T 24328 "toilet paper and their products" is divided into seven sections.

--- Part 1. General principles and terminology;

--- Part 2. Determination of thickness, layer thickness and apparent density of the product;

--- Part 3. tensile strength, tensile energy absorption was measured during the breaking elongation and resistance;

--- Part 4. Determination of wet tensile strength sheets;

--- Part 5. quantitative determination;

--- Part 6. Time and water absorption capacity (basket immersion method);

--- Part 7. Determination of resistance to break spherical degree.

This section GB/T 24328 Part 5.

The partial modification using ISO 12625-6:2005 "paper and tissue products - Part 6. Quantitative Determination" (in English).

This portion of the ISO 12625-6. compared to 2005, the main differences are as follows.

--- With GB/T 450 "and take samples of paper and board samples vertical and horizontal, positive and negative determination" instead of ISO 186:2002, MOD;

--- With GB/T 451.2 "Paper and cardboard quantitative determination" instead eqvISO 536.1995;

--- With GB/T 10739 "Paper, paperboard and pulp sample processing and testing standard atmospheric conditions" instead eqvISO 187.1990;

--- With GB/T 24328.1 "paper and tissue products - Part 1. General principles and terminology" instead of ISO 12625-1:2005, MOD.

This part is proposed by the China National Light Industry Council.

This part of the National Standardization Technical Committee under the jurisdiction of the paper industry.

This section drafted by. China Pulp and Paper Research Institute, the national paper quality supervision and inspection center, China Paper Association Professional Committee of Standardization Members will.

3 Terms and Definitions

GB/T 24328.1 is given and the following terms and definitions apply to this part of the GB/T 24328 of.

Follow the steps specified in this section, the measured mass per unit area of \u200b\u200bpaper and tissue products.

Note. According to GB/T 451.2, in order to quantitatively g/m2 represents.

Principle 4

Determination of the quality and area of \u200b\u200bone or more parts of the sample through the mass per unit area of \u200b\u200bthe sample is calculated quantitatively. For toilet paper after processing Products can also be calculated by measuring the quality and quantitative area.
