Harmonized Test Methods available this month

February 08, 2010 (USA)

The new Harmonized Test Methods: Nonwovens & Related Industries, a collection of standardized test procedures organized by both INDA and EDANA, will be available this month. The publication is referred to as Harmonized Test Methods: Nonwovens & Related Industries.

The first edition of the STM (Standard Test Methods Manual) was published in 2005 and at that time a committee made up of INDA and EDANA members agreed to publish the second edition in five years, at which time it would have revised all of the procedures – such as references, ISO procedures and measurement systems – into a more uniform global format.

“The value of this publication to manufacturing companies is its worldwide acceptance, especially now that the harmonized INDA/EDANA documents are in sync with ISO methods and with the CEN methods,” explains Carl Palenske, a Nonwoven Test Method Consultant who has worked with INDA on the Standard Test Method committee for the last 21 years, including serving as Chairman of the Test Method Committee.

“The harmonizing of test methods to the extent that they are in agreement between all these various organizations adds credibility and makes the harmonized manual a valuable reference tool,” he adds.

The harmonized test methods unite both suppliers and customers in testing parameters and explain the parameters of the product being made and exactly how the tests are performed to verify the attributes/variables of the product. The revision keeps the publication current with new test procedures, with any new productdeveloped and/or new test equipment.

This publication contains several important additions, including:
* The addition of several new procedures.

* On the cover page of each procedure there is a reference block explaining which version is being used and when it was approved.

* This edition harmonizes the WSP methods with ISO. The first edition harmonized INDA and EDANA methods and used the structure (elements) of ISO, but the content for each method adhered closely to the EDANA/INDA harmonization rather than ISO. The following changes were made to harmonize with ISO:

— The inch/pound units were changed to SI units.

— The sampling plans were changed to utilize the ISO method. (The old sampling method did not consider statistical testing of the product; i.e., the size of N as it relates to production, as well as the addition of added statistical sampling).

— All normative references were changed to strictly refer to ISO methods only.

— The reference to “conditioning” was updated to include an ISO standard that was new and referenced testing nonwovens rather than pulp and paper.

— The precision technique or procedure was updated to adhere to ISO standard methods.

— The vocabulary section was expanded with many added terms and definitions.   Source fibre2fashion.com
