Alimur Sir TTQC 2 HW

The document compares two textile testing methods: Constant Rate of Elongation (CRE) and Constant Rate of Loading (CRL). CRE uses a screw mechanism to gradually elongate fabric samples, while CRL uses a water-filled container to gradually increase the load on fabric samples. Both methods are used to measure fabric quality. The document also provides brief descriptions of several standards organizations, including the International Electrotechnical Commission (IEC), International Telecommunication Union (ITU), American National Standards Institute (ANSI), National Institute of Standards and Technology (NIST), and the Global Organic Textile Standard (GOTS).

Comparison between CRE and CRL:

CRE CRL
Meaning CRE means Constant rate CRL means
of elongation. Constant rate of
loading.
Containing CRE method contains screw CRL contains
mechanism. container and water
flow used to
increase load
gradually.
Causes In CRE elongation/ In CRL method
extension causes loading. loading causes
elongation.
Uses CRE is used for measuring CRL is also used
fabric quality. for measuring fabric
quality.
Some Organizations and Standards:

International Electrotechnical Commission


IEC stands for International Electrotechnical Commission. IEC provides a
standardized approach to testing and certification. IEC testing brings together
the agreed upon set of rules, specifications, and terminology that allow
manufacturers to have their devices tested for conformity.

International Telecommunication Union


The International Telecommunication Union (ITU) is a specialized
agency of the United Nations that is responsible for issues that concern
information and communication technologies (ICT).

The American National Standards Institute (ANSI)


The American National Standards Institute (ANSI) is a private,
non-profit organization that administers and coordinates the U.S.
voluntary standards and conformity assessment system. Founded
in 1918, the Institute works in close collaboration with
stakeholders from industry and government to identify and
develop standards- and conformance-based solutions to national
and global priorities.

The National Institute of Standards and Technology (NIST)


The National Institute of Standards and Technology promotes U.S.
innovation and industrial competitiveness by advancing
measurement science, standards, and technology in ways that
enhance economic security and improve our quality of life.

The Global Organic Textile Standard (GOTS)


The Global Organic Textile Standard (GOTS) was developed by leading
standard setters to define world-wide recognized requirements for
organic textiles. From the harvesting of the raw materials,
environmentally and socially responsible manufacturing to labelling,
textiles certified to GOTS provide a credible assurance to the consumer.
