NWSP 10.4 Absorption Capacity (Oil)

Standard:

NWSP

Method:

NWSP 10.4

Title:

Evaluation of Oil and Fatty Liquids Absorption

Scope

The NWSP 10.4 Absorption test method has been developed by EDANA and covers the evaluation of nonwoven fabrics designed to absorb oil and other fatty liquids. Such products are commonly known as sorbent products. This method is directly derived from NWSP 10.2.R3 and covers two parameters, which should be tested sequentially.

a) The liquid absorbency time.

b) The liquid absorption capacity

These tests are applicable to any fabric designed to absorb oil, in particular those made out of meltblown polypropylene. The SI values are regarded as the official standard system of measurement for this standard test method.

The SI values are regarded as the official standard system of measurement for this standard test method.

Principle

The test consists in imbibing a specimen with a specified liquid up to saturation, measuring the time taken to saturate the specimen, and measuring the amount of liquid retained by the specimen after a time during which excess liquid is allowed to flow freely out of the specimen.

Samples

IPS uses mineral oil unless a different oil is specified by the customer.
