Research Triangle Park, NC (22 June 2010) – The ISA100 Wireless Compliance 
Institute (WCI) today announced the selection of National Technical Systems, Inc. (NTS) 
(NASDAQ:NTSC) as its independent third-party lab to provide conformance testing for the 
ISA100.11a certifications starting this month. NTS provides companies and government 
organizations throughout the world with process and product compliance services, 
managed engineering services, design engineering services, and program 
management support.

“WCI selected NTS as the first independent provider of ISA100.11a conformance
testing based on its depth of capabilities in wireless protocol testing, quality of 
operations, and geographic support,” said Andre Ristaino, managing director of WCI.

“We are pleased to be selected as the first lab to provide ISA100.11a conformance 
testing,” said Osman Sakr, CTO of National Technical Systems.  “The ISA100.11a 
standard will greatly enhance the implementation of wireless systems in the automation 
and control environment.”

With the recent availability of the ISA100.11a Stack Conformance and Device 
Interoperability Test Kits designed to verify conformance, suppliers will be able to use 
the same test kits that NTS uses during certification testing. Suppliers will use these 
test kits as part of their quality assurance processes and in preparation for formal 
conformance testing.

NTS is an ISO/IEC 17025 accredited test lab.

Webcast to Detail Step-by-Step Certification Process

The WCI has scheduled a webinar which provides guidance to suppliers seeking to 
certify devices to the ISA100.11a standard. The webinar will include a step-by-step 
description of the conformance process, including whom to contact first, and how to 
get support during the product development process.

Webinar Date: Tuesday, 20 July 2010 at 11 a.m. ET USA

The ISA100.11a industrial wireless networking standard is the first in the ISA100 family 
of standards. This wireless mesh network standard protocol helps supplier companies 
build interoperable wireless automation control products. As a result, manufacturing and 
processing plants are able to create, modify, optimize, and scale a wireless network 
quickly, cost-effectively, and seamlessly.

Future ISA100 standards will include support for backhaul functionality, factory 
automation, and other key-use cases. Details on the approved standard, the ISA100 
roadmap, and use-case presentations are available at www.isa.org/ISA100.
