Overview
SIST EN ISO 9073-2:1999 is a critical European standard that specifies test methods for determining the thickness of nonwoven textiles under a defined pressure. It replaces the original 1989 edition to provide updated, precise guidelines for accurately measuring thickness in both normal and bulky nonwovens. Developed under ISO 9073-2:1995 and standardized by CEN, this document ensures consistency and reliability in textile thickness testing across the industry.
Thickness measurement is vital for evaluating the physical properties and performance of nonwoven materials used in diverse applications. By applying a standardized pressure during testing, this method offers repeatable results that reflect real-world conditions more accurately than simple thickness gauging.
Key Topics
-
Scope of Thickness Measurement
Focuses on nonwoven textiles, encompassing both standard (normal) and voluminous (bulky) variants.
-
Measurement Under Specified Pressure
Thickness is determined by applying a defined pressure ensuring uniform compression for reliable comparisons.
-
Methodology
Detailed procedures for sample preparation, conditioning, and execution of thickness tests.
-
Calibration and Equipment Requirements
Recommendations for the instruments used to measure thickness, including calibration standards.
-
Data Interpretation
Guidelines on reporting thickness values and handling variations due to material heterogeneity.
Applications
-
Quality Control in Textile Manufacturing
Regular thickness testing using SIST EN ISO 9073-2:1999 helps ensure product consistency and adherence to performance specifications.
-
Product Development and Material Selection
Accurately measuring fabric thickness supports development of nonwoven materials tailored for filtration, medical, automotive, or hygienic uses.
-
Regulatory Compliance
Assists manufacturers in meeting industry norms and customer requirements by providing internationally recognized thickness testing protocols.
-
Research and Technical Analysis
Enables standardized evaluation of innovations in nonwoven textiles by assessing changes in material structure and density.
