TESTING:
Testing is the method or process by which checking and verifying of materials occurred. It is the process for evaluating the quality of the objects by accompanying some standard. Testing should be accomplished using some standard test method to compare the test results.

In garment manufacturing, testing means the required quality of the product which can satisfy buyers’ as well as consumers’ needs.

Global quality standards of apparel are technology driven, benchmarked by the buyers and ultimately product oriented. Quality evaluation is not only to ensure a quality product but also to endorse product safety, prevent recalls, minimize customer complaints and promote repeat sales

HISTORY:
Apparel testing was first institutionalized by AATCC (American Association for Textile Chemists and Colorists) in 1921.

March 31, 1940 – New York retains the outstanding position as the retail testing ground for fashion merchandise, and at last 85% of apparel and accessories get their initial test of consumer response in local stores.

June 17, 1951 – Installation of complete textile testing laboratory in the Chicago Reliance Manufacturing Company.

April 12, 1955 – A new testing and information center established by New York’s Fashion Institute of Technology aimed at improving techniques in fabricating textiles into apparels.

1973 – Texanlab was founded. It is now one of the largest independent textile testing institutes in Asia.

October 1, 2003 – The American Society for Testing and Materials (ASTM) has created ASTM F739 as a standard test method for measuring permeation resistance.

In June 2000, Bangladesh Bureau Veritas Group (Merchandise Testing Laboratories, Inc. or MTL) set up the first internationally recognized apparel testing service in Bangladesh.

In January 2002, MTL and ACTS Testing Labs, Inc. combined into one entity.

TESTING METHODS:
