No.: 11-0105\nDear Mr. Reese:\nThis responds to your April 18, 2011 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) applicable to the definition of\ncorrosive materials.\nIn your letter, you state that your company, Dupont, receives metal corrosion test results\nfor one of its products. You indicate that the laboratory test report for the product states it\nis not corrosive to metals at a rate of 6.25 mm/yr, but it exhibits \"localized corrosion\" at\nthe liquid/vapor interface exceeding 120 mm when exposed for seven days. You provide\ndata in an attachment of the metal corrosion test results. You ask if a shipper is required to\nuse both \"uniform corrosion\" and \"localized corrosion'~ data when determining whether a\nmaterial meets the definition of a Class 8 corrosive material based on its corrosive effects\non aluminum or steel.\nThe answer is yes. Under the HMR, both tests must be considered when determining if a\nmaterial is corrosive. It is the opinion of this Office that based on the information from the\nresults of the tests your company performed, your material is considered a Class 8\ncorrosive material. (See § 173.136.)\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\nT.

I am a hazardous materials, regUlatory compliance resource for ten of DuPont's businesses and three\nDuPont Joint Ventures (JVs).\nOne of my JVs recently received metal corrosion test results for one of their products, see attachment Metal corrosion\ntest results. The issue they have with the laboratory results is the data regarding \"localized corrosion depth\". According\nto the laboratory test report, the product is not corrosive to metals at a rate of 6.25 mm/yr, but does exhibit \"localized\ncorrosion\" at the liquid/vapor interface exceeding 120 mm when exposed for 7 days. The Testing Laboratory reported the\nproduct meets the hazard class 8 definition of a corrosive material in accordance with the DOT's HMR based on the\nobserved \"localized corrosion depth\" test results. A copy of the UN class 8 metal corrosion pass/fail tables is attached. I\nknow uniform corrosion to metals is in 49CFR, but I'm not sure if \"Iocalized corrosion\" is part of the class 8 definition.\nQuestions 1.\nIs a shipper required to use both \"uniform corrosion\" and \"localized corrosion\" data when determining if a material\nis a class 8 corrosive material based on its corrosive effect on aluminum or steel? or\n2. Is a shipper only required to use \"uniform corrosion\" data when determining if a material is a class 8 corrosive\nmaterial based on its corrosive effect on aluminum or steel?\nWe appreciate you looking into this matter, and providing us with your interpretation or guidance.\nThank you, and Best Regards, TomReese\nDistribution Safety &Regulatory Compliance Consultant\nDuPont Sourcing &Logistics\nDistribution Safety & Security Team\n4417 Lancaster Pike\nBarley Mill Plaza 22/2226\nWilmington, DE 19805\nPhone: (302) 992-3483 (Ducom 9923483)\nFAX: 1-302-355-2891 (This not a Ducom number)\nInternet: Thomas.C.Reese-1@usa.dupont.com\nHours: 8:00 AM - 5:00 PM\nThis communication is for use by the intended and contains\ninformation that may be Privileged, confidential or copyrighted under\nlaw.
