Standardized methods
Recognized protocols, applied with control.
Method selection begins with the product, claim, market, and required level of comparability—not simply the name of a standard.
HCPA
Household and Commercial Products Association performance methods for cleaning and consumer specialty products.
AATCC
Textile and fabric-care methods covering appearance, colour, staining, dimensional change, and related performance.
IKW
Consumer-relevant European methods for automatic dishwashing, hand dishwashing, laundry, hard-surface cleaning, and material compatibility.
Custom methods
When the standard does not answer the real question.
Tandell can adapt recognized methods or develop purpose-built comparative protocols with defined substrates, soils, application conditions, controls, replicates, scoring, and acceptance criteria.

Design the evidence before finalizing the claim.
We help customers translate proposed claim language into an appropriate comparison, test population, use condition, endpoint, and reporting plan. Final legal and regulatory claim approval remains with the customer and its advisors.
