Electrostatic Discharge Association (ESDA) standards and publications are designed to serve the

public interest by eliminating misunderstandings between manufacturers and purchasers, facilitating

the interchangeability and improvement of products, and assisting the purchaser in selecting and

obtaining the proper product for his particular needs. The existence of such standards and publications

shall not in any respect preclude any member or non-member of the Association from manufacturing

or selling products not conforming to such standards and publications. Nor shall the fact that a standard

or publication that is published by the Association preclude its voluntary use by non-members of the

Association whether the document is to be used either domestically or internationally. Recommended

standards and publications are adopted by the ESDA in accordance with the ANSI Patent policy.

Interpretation of ESDA Standards: The interpretation of standards in-so-far as it may relate to a specific

product or manufacturer is a proper matter for the individual company concerned and cannot be

undertaken by any person acting for the ESDA. The ESDA Standards Chairman may make comments

limited to an explanation or clarification of the technical language or provisions in a standard, but not

related to its application to specific products and manufacturers. No other person is authorized to

comment on behalf of the ESDA on any ESDA Standard.

THE CONTENTS OF ESDA'S STANDARDS AND PUBLICATIONS ARE PROVIDED "AS-

IS," AND ESDA MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR

IMPLIED, OF ANY KIND WITH RESPECT TO SUCH CONTENTS. ESDA DISCLAIMS

ALL REPRESENTATIONS AND WARRANTIES, INCLUDING WITHOUT LIMITATION,

WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR

USE, TITLE, AND NON-INFRINGEMENT.

ESDA STANDARDS AND PUBLICATIONS ARE CONSIDERED TECHNICALLY SOUND

AT THE TIME THEY ARE APPROVED FOR PUBLICATION. THEY ARE NOT A

SUBSTITUTE FOR A PRODUCT SELLER'S OR USER'S OWN JUDGEMENT WITH

RESPECT TO ANY PARTICULAR PRODUCT DISCUSSED, AND ESDA DOES NOT

UNDERTAKE TO GUARANTEE THE PERFORMANCE OF ANY INDIVIDUAL

MANUFACTURER'S PRODUCTS BY VIRTUE OF SUCH STANDARDS OR

PUBLICATIONS. THUS, ESDA EXPRESSLY DISCLAIMS ANY RESPONSIBILITY FOR

DAMAGES ARISING FROM THE USE, APPLICATION, OR RELIANCE BY OTHERS ON

THE INFORMATION CONTAINED IN THESE STANDARDS OR PUBLICATIONS.

NEITHER ESDA, NOR ITS PRESENT OR FORMER MEMBERS, OFFICERS,

EMPLOYEES OR OTHER REPRESENTATIVES WILL BE LIABLE FOR DAMAGES

ARISING OUT OF, OR IN CONNECTION WITH, THE USE OR MISUSE OF ESDA

STANDARDS OR PUBLICATIONS, EVEN IF ADVISED OF THE POSSIBILITY

THEREOF. THIS IS A COMPREHENSIVE LIMITATION OF LIABILITY THAT APPLIES

TO ALL DAMAGES OF ANY KIND, INCLUDING WITHOUT LIMITATION, LOSS OF

DATA, INCOME OR PROFIT, LOSS OF OR DAMAGE TO PROPERTY AND CLAIMS OF

THIRD PARTIES.
