3 Terms and definitions
The following terms and definitions defined in GB/T 24328.1 apply to this document.
3.1 Single-plythickness
The measured distance between the two surfaces of a single-layer toilet paper under a specified static pressure.
Note. Single "layer" refers to toilet paper that cannot be layered, such as a single-layer toilet paper produced directly by a toilet paper machine.
3.2 Singlesheetthickness
Under a specified static pressure, the measured distance between the two surfaces of a single (single finished layer) toilet paper product.
Note. A single "sheet" is a finished product processed by a single or multiple layers of toilet paper, such as a toilet paper product that has been processed.
3.3 Bulkingthickness
The thickness of a single sheet (single finished layer) of toilet paper and its products is determined by a stack of multiple sheets (multiple finished layers) measured under a specified static pressure.
Calculated by adding thickness.
