AATCC Launches 2019 Proficiency Programmes for Lab Performance Verification

Labs may now register online for all 2019 AATCC Proficiency Testing Programmes (PTP) programmes. PTPs support certification and continuous improvement initiatives for textile laboratories.

Six AATCC programs cover Antibacterial, Appearance, Colour Evaluation, Colourfastness, Fibre Analysis, and Water Resistance test methods and evaluation procedures. Samples are selected to provide consistent results in a meaningful range for each program.

Online registration, launched in September 2018, allows labs to complete registration and credit card payment in one easy step.
