Corrositex is an invitro
test that determines chemical corrosivity and permits assignment of
Packing Group classification for Class 8 corrosives. This test replaces
the rabbit test of dermal corrosivity by providing a reliable means of
mimicking this test. The proprietary core technology of the Corrositex
test is based upon a biomembrane and chemical detection system, which
becomes colored when exposed to potentially corrosive substances.
How the Test Works
testing system consists of a glass vial filled with a chemical
detection fluid capped by a proprietary bio-barrier membrane, which is
designed to mimic the effect of corrosives on living skin. As soon
as the corrosive sample destroys this bio-barrier, the fluid below
changes color or texture. Users simply record the time it takes for the
sample to break through the membrane. Then, depending on their needs,
they can assign the proper U.N. Packing Group classification for U.S.
DOT or EPA compliance, or use the data as a ranking tool or to
substantiate marketing claims.
Why Use Corrositex?
Because it will save you time and money.
Time Savings: Unlike animal testing that can take 2 to 4 weeks, Corrositex testing can provide a Packing Group determination in as little as 3 minutes and no longer than 4 hours.
Cost Savings: In a recent evaluation, one customer saved up to
$50,000 annually, in shipping costs, for a single compound when using
the Corrositex test to define the Packing Group
instead of relying on pH. In addition to the reduction in shipping
charges, additional cost savings are found in the areas of workplace
safety and MSDS development.
Regulatory Acceptance. Following is a list of agencies that accept Corrositex. This list continues to grow as regulatory bodies look for more accurate, cost-effective and humane testing methods. Copies provided upon request.
Department of Transportation - DOT-E 10904
Original exemption granted April 28, 1993
special permit is no longer necessary. The provisions of DOT-SP 10904 were
incorporated into the Hazardous Materials Regulations under Docket No. HM-215K
in a final rule published in the Federal Register on January 19, 2011 (76 FR
3308). The authority is now contained in § 173.137. A
