ISO 13936-3 Determination of Relaxation Shrinkage

Comprehensive Guide to ISO 13936-3 Determination of Relaxation Shrinkage Laboratory Testing Service Provided by Eurolab

ISO 13936-3 is a laboratory test standard that determines the relaxation shrinkage of textile materials. This standard is widely recognized and accepted globally, with numerous countries adopting it as a national standard. The standard is developed and maintained by the International Organization for Standardization (ISO) through a consensus-driven process involving experts from various industries.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 13936-3 testing is governed by international and national standards. In the European Union, for example, EN ISO 13936-3 is the applicable standard, while in the United States, ASTM D4032 is the equivalent standard. Other countries have their own national standards that may differ from the ISO standard.

International and National Standards

The following are some of the relevant international and national standards governing ISO 13936-3 testing:

Standard Development Organizations

The standard development organizations involved in the creation and maintenance of ISO 13936-3 are:

These organizations work together to develop, maintain, and update standards through a consensus-driven process involving experts from various industries.

Standard Evolution and Update

Standards evolve over time as new technologies and techniques emerge. ISO 13936-3 has undergone several revisions since its initial publication in 2002. The current version (2014) includes updates to the testing methodology, equipment requirements, and data analysis procedures.

Standard Compliance Requirements

Various industries require compliance with ISO 13936-3 testing as a condition for product certification, labeling, or regulatory approval. These industries include:

Compliance with ISO 13936-3 testing demonstrates a manufacturers commitment to quality and safety.

Why This Test is Needed

ISO 13936-3 testing is essential for ensuring the quality, safety, and performance of textile materials. Relaxation shrinkage can affect the dimensional stability and durability of textiles, leading to premature wear and tear. By determining relaxation shrinkage, manufacturers can identify potential issues and take corrective action.
