Standard Activities Overview

Overview of the Standardization System

The IHVCA's primary goal is to enhance the quality of life and the safety of end users by promoting and facilitating High Visibility Clothing Standards and ensuring their integrity.

ISO WG Project CD20471 is proposing a new ISO standard “High-visibility warning clothing for professional use – Test methods and requirements”. The draft was disapproved by voting members of ISO on January 15, 2011. The received comments will be resolved in ISO/TC 94/SC 13/WG 1/PG 20471. The next meeting of PG 20471 will be held in Madrid, Spain, 2011-03-15/16. The Target date of discussion is 2010-4-28, Final Date of discussion of 2011-4-28 and IS date is 2011-10-28.

The IHVCA High Visibility Clothing Standard draft is posted for public opinion and will be amended based on comments accordingly. The final version will be voted upon and will be scheduled publish on April of 2011.

A Letter to ISO /TC 94/SC 13 Members

Please vote Disapproval to ISO DIS 20471.2 High Visibility Clothing Standard Draft 2, where numerous flaws were found. Published science and theories prove that the specifications fail to show a consistency with the required minimum coefficient of retroreflection (RA) for Entrance Angles and Observation Angles in relation to the Critical Detection Distance.

The specifications in the draft 2 also eliminated the option of users’ preference. Important elements of clothing such as comfort and fashion have been limited from possible designs of current safety garments.

In the draft, more stress is focused on the need for certain reflective tapes than the safety and wellbeing of the end users. It has encouraged mass production but restricted the development and creativity of the local business.

To ISEA High Visibility Group members

Numerous flaws with the prevailing EN471:2003, ANSI/ISEA 107,207, and ISO DIS 20471 standards were found. All of the above standards are using the same false data for retroreflection. Published science and theory proves that the current specifications fail to show a consistency with the required minimum coefficient of retroreflection (RA) for Entrance Angles and Observation Angles in relation to the Critical Detection Distance. In above standards, more stress is focused on the need for reflective tapes than the safety and wellbeing of the end user.

A presentation of field testing data, scientific theories and alternative designs of high visibility clothing will be given in AATCC symposium held at Los Angles, California on December 7-9, 2011. International High Visibility Clothing Association (IHVCA) standard and test method will be introduced. You are welcome to attend the meeting and your comments will be appreciated.

Part of the above issues had been presented in the ISEA group meeting held in Baltimore on June 14, 2010. I would happy to present the whole theory in next group meeting if so requested.

Representing IHVCA, I would like to invite ISEA high visibility products group in a joint effort to resolve these safety issues, either through amending the prevailing ANSI/ISEA 107, 207 standards or developing a new ANSI standard.
