Finished Product Testing
Independent Testing for Absorbent Product Performance
Finished absorbent product performance depends on more than the properties of the raw materials. Product design, material selection, and manufacturing processes can all influence how an absorbent product performs.
​
Absorbent Product Services (APS) provides targeted finished absorbent product testing to support SAP characterization, supplier comparisons, and performance investigations. Raw SAP testing and finished-product evaluations can be performed within the same project to help assess how material differences relate to finished-product performance.
​
Whether you are comparing products, evaluating alternative materials, or investigating unexpected results, APS provides objective testing data to support informed decisions.
Products Evaluated
APS provides testing services for a range of disposable absorbent hygiene products, including:
​
-
Baby diapers and training pants
-
Adult incontinence briefs and protective underwear
-
Absorbent pads and liners
-
Other absorbent hygiene articles, subject to project requirements
Testing methods and conditions are selected according to the product type and the objectives of the evaluation.
How to Get Started
1. Tell Us What You Need to Evaluate
Share your product type, testing objectives, and any specific performance questions.
2. Receive a Testing Proposal
APS reviews the project requirements and provides a proposed testing scope, pricing, and estimated turnaround time.
3. Receive Your Results
Samples are tested under the agreed conditions, and results are provided in a confidential laboratory report.

Absorbent Capacity & Retention
Capacity and retention testing measure how much liquid a finished absorbent product absorbs and how much it retains under defined test conditions. APS offers established procedures and product-specific testing approaches.
Total Absorbent Capacity
Determines the amount of liquid absorbed by a finished absorbent product under specified test conditions
ISO 11948-1 — Whole-Product Absorption Capacity
Determines the maximum absorption capacity of a finished urine-absorbing product under specified test conditions.
NAFC — Retention Capacity
Determines the amount of liquid retained by a finished absorbent product following absorption capacity testing and centrifugation.
Testing methods and available variations:
-
Baby diaper capacity and centrifugal retention procedures
-
Sectional absorbent capacity
-
Product-specific immersion and drainage conditions
-
Comparative capacity and retention evaluations
Customized Testing & Investigations
Not every absorbent product performance question can be answered through a standard test procedure. APS works with clients to establish testing approaches suited to specific materials, products, and investigation objectives.
Project-Specific Testing
Develops or adapts testing approaches to evaluate specific absorbent product performance questions.
Comparative Performance Evaluations
Evaluates differences between finished absorbent products, materials, or product designs under defined testing conditions.
Testing conditions and available variations:
-
Modified testing conditions and protocols
-
Comparative product performance testing
-
Investigation of unexpected performance results
-
Client-specific testing requirements
SAP Extraction, Recovery & Characterization
Recovering superabsorbent polymer from a finished absorbent product requires specialized laboratory techniques and experience. APS provides SAP recovery and subsequent characterization to support material comparisons and product investigations.
SAP Extraction & Recovery
Recovers superabsorbent polymer from finished absorbent products for subsequent material characterization
Recovered SAP Characterization
Evaluates the performance properties of recovered superabsorbent polymer using established SAP testing methods.
Available evaluations:
-
SAP extraction and recovery
-
Raw and recovered SAP performance comparisons
-
Comparative analysis of recovered SAP samples
-
Project-specific material investigations
Acquisition & Rewet
Acquisition and rewet testing evaluate how finished absorbent products handle liquid during use. These measurements can help identify performance differences between products or evaluate the effects of material and design changes.
Acquisition Time
Determines the time required for a finished absorbent product to absorb a specified volume of test liquid.
Rewet
Determines the amount of liquid released from a finished absorbent product under specified pressure following liquid acquisition.
Testing conditions and available variations:
-
Insult volume and dosing apparatus
-
Acquisition under applied load
-
Single or multiple insults
-
Product-specific testing protocols
