Rothwell scale

From Wikipedia, the free encyclopedia

The Rothwell scale, or Rothwell system, or Rothwell method, applied to incontinence care products, is a scale that shows how absorbent a particular incontinence pad or adult diaper is, and how much liquid it can absorb and hold before it is likely to leak due to overfill.

The system provides a quick reference for assessing how much liquid can be held by a sheet, pad or diaper, and therefore how appropriate it will be for a particular individual in any given circumstance. The scale is based on the total absorbency test ISO 11948–1. The scale runs from 1 to 22, with 1 indicating the least liquid absorbed, measured in grams, and 22 the most liquid absorbed. The scale also applies a prefix to show what type of product is being referred to, with pads and sheets having an “I” prefix, and all in one diapers using a D prefix.
