           Starting in 2011 Pair O Docs® Professionals is offering constant temperature corrosion stability testing as part or our Beaker-to-Boxcar® line of corrosion testing services.

 

Two ways our new service can help you with your corrosion testing needs:

1. We conduct corrosion storage tests at our facilities

2. We examine containers from your corrosion storage test facilities

What you get when Pair O Docs® examines container samples from your storage tests

• A summary of the results for each container corrosion examination

• Statistical lifetime modeling of container service lifetime when pitting corrosion is found

• A final written report summarizing the findings from the static storage test along with recommendations

 

What you get with the Pair O Docs® storage test protocol

•  Multiple corrosion evaluations on containers stored at ambient and 100 oF (38 oC) temperatures

• Static weight loss measurements at ambient temperature

• Dynamic weight loss measurements at ambient temperature

  • Measures weight loss from aerosol valves wetted by the product, and replaces inverted container storage

• Container pressures as a function of time for static and dynamic storage at ambient temperature

 

What you get with the Pair O Docs® storage test protocol

• Test documentation:

  • A summary of the results from each container corrosion examination

  • Statistical lifetime modeling of container service lifetime when pitting corrosion occurs

  • Graphs of container weight loss as a function of time for both static and dynamic weight loss measurements

  • Graphs of container pressure as a function of time

  • A final written report summarizing the findings from the storage test along with recommendations

• Generation of a confidential company corrosion data base that is updated with each subsequent storage test

 

We could also integrate results from Pair O Docs® electrochemical corrosion tests with corresponding storage test data

 

Our standard protocol does not include a) samples for product efficacy testing, b) evaluation of aerosol spray patterns or particle size distribution, c) measurement of spray rates, and d) storing containers above 100 oF (38 oC).  We could add one or more of these procedures/parameters for additional cost.

 

The advantages to using Pair O Docs® for your constant temperature corrosion storage testing:

• Dr. Steve Tait has 40 years experience in corrosion engineering and science; over 30 of these years includes experience with aerosol container corrosion

• Pair O Docs® test protocols are based on aerosol container corrosion research

• We typically examine more containers for corrosion than other protocols

• Our protocol for higher temperature storage testing is based on actual daily historical weather data and simulates 3 years of exposure above 90 oF (32 oC)

• We build a company corrosion database that can be used to shorten new product and line extension development times (from a corrosion perspective)
