Dear SRM Customer:

Since 1998, NIST has issued 188 new and renewal NIST Standard Reference Materials (SRMs). This special

catalog supplements the existing printed NIST SRM catalog to help you find exactly the material you need.

This catalog is divided into six sections, grouping SRMs into major categories of use. We encourage you to check

all categories, as your use may not fit exactly into these categories. The supplemental information contains a description of each material and the date the material was issued. The latter is to ensure that the material in your possession is the most current.

In addition, I want to announce that online ordering of NIST Standard Reference Materials is now available for

U.S. customers only. The NIST SRM Website http://wvm.nist.gov/srm now provides easy access to the information and services that customers need most. A single mouse click reaches the current price list, all new and

newly renewed NIST SRMs, and the complete list of all NIST SRMs in order by SRM/Catalog number Orders

can be placed online with virtually no extra effort. Visit the site TODAY! http.7/www.nist.gov/srm

As usual, if you have any questions and comments, contact the NIST SRM Sales Department at: E-mail: srminfo@nist.gov

Fax:301-948-3730

Tel: 30 1 -975-6776.

We look forward to helping you meet all your Standard Reference Materials needs.

Standard Reference Materials Program
New/Renewal Industrial Standard Reference Materials (SRMs) for Ferrous Metals, Nonferrous

Metals, Microanalysis, High Purity Materials, Ceramics and Glasses, Cement, and Engine Wear

Measurements.

There are eighteen new and nine renewal industrial materials available. In the area of ferrous and nonferrous

metals there are eight new zinc aluminum alloys, nitrogen in low alloy steel, nickel based superalloy, and two new

refractory alloys. There are five renewals of high purity materials with a range from sucrose, potassium hydrogen

phthalate, acetanilide, cystine and chlorine isotopic, and three new reference materials, isotopically characterized

carbon dioxide. There is a new silicon nitride powder, three renewal cements, one renewal of wear metals in oil, and a new lubricating oil additive package.
