ASTM D4151 Dimensional Stability after Laundering Laboratory Testing Service: A Comprehensive Guide
ASTM D4151 is a widely recognized standard for testing the dimensional stability of fabrics after repeated laundering. This standard is developed and published by the American Society for Testing and Materials (ASTM), a leading developer of international voluntary consensus standards.
The standard requires that fabric samples be subjected to multiple cycles of washing, drying, and ironing to simulate the effects of repeated use in garments. The dimensional stability of the fabric is then measured using a series of tests, including tensile strength, elongation at break, and shrinkage.
ASTM D4151 is part of a larger family of standards related to textile testing, which are widely adopted globally. Some of the key international and national standards that apply to this specific laboratory test include:
ISO 139:2015 (Textiles Standard atmospheres for conditioning and testing)EN 22765 (Textiles Domestic washing and drying procedures for test specimens)TSE L 20 (Turkish Standards Institution) - Textiles - Washing, drying, and ironing testsThe development of standards such as ASTM D4151 is overseen by standard development organizations (SDOs), which are responsible for creating and maintaining the technical content of standards. The SDOs involved in developing this standard include:
American Society for Testing and Materials (ASTM)International Organization for Standardization (ISO)European Committee for Standardization (CEN)Standards evolve over time to reflect advances in technology, changes in regulations, or shifts in industry practices. New editions of standards are published periodically, often incorporating new testing methods, apparatus, or procedures.
ASTM D4151 Dimensional Stability after Laundering testing is essential for various industries and sectors that require textile products to meet specific performance criteria. Some of the key reasons why this test is required include:
