Dynamic Relative Humidity Creep Decay in Corrugated Packaging Substrates
Dynamic relative humidity cycling drives exponential creep decay in corrugated board through mechano-sorptive bond cleavage, requiring dynamic safety factors.
ISO/IEC 17025 Testing
Accreditation Framework
Laboratory accreditation framework establishes the general requirements for the competence, impartiality and consistent operation of testing and calibration laboratories. Iso/iec 17025 testing ensures that the data generated for paper physical properties or chemical safety is technically valid and internationally recognized. It requires a rigorous quality management system and the demonstration of technical proficiency by the staff.
Audit Process
Audit procedures examine everything from the calibration of tensile testers to the environmental control of the conditioning room. Measurement uncertainty must be calculated and reported for every test result to provide a confidence interval. Participation in proficiency testing programs allows a lab to compare its results with other accredited facilities worldwide.
This transparency is vital for resolving disputes between buyers and sellers regarding material specifications.
Global Recognition
Certifying a paper mill under this standard gives customers confidence that the reported grammage and burst strength are accurate. Non-accredited labs may produce data that is not legally defensible in a commercial claim. Many global retailers now mandate that all safety and performance testing be performed only by labs holding this specific accreditation.
It reduces the need for redundant testing when materials move between different countries. Technical competence is verified through regular on-site inspections by national accreditation bodies.
