O'BREN To: Jim O'Steen Ed Mazzullo / From: Lary Bin Ten Re: Hewlett-Packard ink testing I appreciated the chance to talk to you about the Hewlett-Packard inkjet cartridges and our pending request for an approval. In order to provide you with more information about the ink itself, I have enclosed two items First is an MSDS for the most aggressive of the range of inks aflected, Zaphod Yellow. As you can see, the flash point is greater than 200°F The second enclosure is a rest report. As noted in the onginal application, the cartridges range in capacity from about 35 mi to 750 mi, with more than 90% being about 35 ml. Because the device contains the ink, and the device itself is extensively overpacked, the likelihood of any release is virtually non-existent. If there were a release, however, the amount released would be small. This is an ink and it is intended to dry rapidly. While it would dry faster on paper, nonetheless even a spill onto a metal surtace dries quickly. In order to assess the corrosive effects of a simulated spill, i.e., in which the steel coupon is wet with the ink but then the ink is allowed to dry, the company ran three tests. The test method is somewhat different from the draft I sent you last week. In the enclosed test report, three sample steel coupons were used. As described in for a week. The assumption is that the comosive effects on steel stop when the ink dries, and this longer test should confirm that assumption. I will call one of you tomorrow to see how this information might be used to support the requested "quantity and form" approval requested Thank you.#

The memo is structured by giving a background as to why the experiment was performod, the summary of the results, followed by the analysis procodure usod. Background and Analysis Goal discovered that the color (yellow, magenta and cyan) inks that are used in the No. 10 and No. 80 inkjet supplies During routine internal product testing of the inks and cartridge material used to manufacture inkjet supplies, it was exceeded the federal waste and transportation threshold for corrosivity to steel. The method used to determine corrosivity is found in EPA 530/SW-846 Method 1110, Corrosivity Towards Steel. heated to 55 degrees C and agitated. Although the inks exhibit the corrosivity characteristic under these test The method calls for the immersion of an SAE 1020 steel specimen in approximately 1000-ml of liquid, which is conditions, it was not known if they would corrode steel under more "real world" conditions. The analysis goal was to simulate an ink spill and determine if the ink would continue to exhibit the corrosion characteristic while drying or when dry. It is hoped that the data may answer this question. Summary of Results yellow showing the highest corrosion rate. For this reason, Zaphod yellow was chosen as the ink for this The ink used in the No. 10 and No. 80 inkjet supply were developed under the codename Zaphod, with Zaphod the Acid/Base fume hoods in the HP Corvallis Building 7 Analytical Lab as shown in Figures I and 2. For quality experiment. Three SAE1020 round steel coupons were used as the specimens. The experiment was set-up in one of control, a specimen was also exposed to DI Water, while another specimen was suspended in the hood, but not exposed to any liquid. Both the specimen and the liquid weights were measured on a Sartorius Model R200 year. The conditions of the analyses are listed at the end of this document. Balance, shown in Figure 3, capable of measuring out to five significant figures and calibrated in September of this the corrosion rate in millimeters per year (campy) of the three specimens used in the experiment. It can be seen from No significant differences were detocted between the specimens with regard to their corrosion rates. Table 1 shows the table that there were no significant differences detected between the spocimens with regard to their corrosion rate.#

Each specimen was stamped with a material code (C1020) and individual identification number (AOXXX). The sealed packets for the specimens used in this experiment were not opened until the day of the experiment and were always handled using nitrile gloves.

After exposure, each spocimen was immersed in a 1:10 non-chlorine cleanser/tap water mixture at ambient temperature and allowed to soak for S minutes. Then, the immersed specimens were placod on an electric stirrer for another five minutes. The specimens were removed from the immersion jars, rinsed with tap water and patted dry using a sterile Tea-Wipe. The specimens were weighed and sent back to the SEM lab, where post-exposure micrographs were taken. While at the SEM lab, the specimens were cleaned with high-pressure COr gas to remove ink residue.

As you know, while we have been discussing this application, the company has continued to have corrosivity tests conducted on its inks under the standards in the U.S. and the international dangerous goods regulations. This has been made somewhat more difficult because of the commercial unavailability of the P3 and P235 steels cited in the regulations. Both title 49 CFR and the UN Orange Book, however, indicate that test steels of "a similar type" may be used to determine the classification. Enclosed are the most recent results using K02400 steel to test the company's Zaphod Yellow Ink. This ink was chosen because both company chemists and outside laboratories determined it would be the most aggressive of the inks offered in the cartridges. Along with these test results is a chart comparing the chemistry of K02400 steel to that of P3 and P235 steels. Based on this chart, we believe K02400 to be a "similar" steel to P3 and P235 as that term is used in the regulations.#

Page 29Based upon the 14-day test results utilizing this steel, we believe that the ink does not fall within the scope of the hazardous materials regulatory definitions for steel. corrosion. We chose this time period because we know it has been used before in the context of DOT corrosive materials classification, and because it appears to be a closer replicate to an annual corrosion rate as specified in the regulations than a shorter test period. As indicated in our original application, based upon actual testing, we know that the ink is not skin or aluminum-corrosive, and that it does not meet the definition of any other hazard class. If, upon your review of this data and test results, you agree with my conclusion that these inks do not fall not within the scope of the regulations, consider this a request to withdraw the pending approval application. Please contact me if you have any questions on this material. Thank you. For Hewlett-Packard Enclosures#

Page 34-. January, 2001 Mr. Lawrence W, Bierlein 2175 K Street, NW Washington, DC 20037 Dear Mr. Bierlein: On September 1, 2000, on behalf of Hewlett-Packard Company, you applied for an approval to ship certain inkjet cartridges as unregulated materials. This is in response to your subsequent letter of January 5, 2001, enclosing results of certain steel corrosion tests and a comparative chart on steel compositions. We have reviewed thai test data and chart, and conclude that the KO2400 steel rested is sufficiently "similar to" P3 and P235 steels, as that term is used in the Hazardous Materals Regulations (HIMR) and the UN Model Regulations on the Transport of Dangerous Goods, to be accepted for Class 8 classification purposes. We also conclude, based upon the 14-day test results you provided, that the ink in the Hewlett-Packard inkjet printer cartridges does not meet the definition of a corrosive material as set forth in the U.S. HMR in 49 CFR 173.136-137, and in international regulations based upon Chapter 2.8 of the UN Model Regulations on the Transport of Dangerous Goods. Accordingly, because the ink is not regulated as a hazardous material, the approval you originally requested is not necessary and, per your letter, we are returning the approval application to you. Sincerely,#
