Q: How do I know what tests I need?
A: That is common and part of the solution that Stresau Laboratory provides its clients is establishing what tests are needed. If you are at this stage, you can give us a call or, consider these general guidelines. What regulatory jurisdiction and type is involved with the material: transportation, storage, handling and exposure; domestic or international; laboratory prototype or production quantity. Where your material fits in these choices will suggest which regulations to reference for testing. Internal safety concerns, rather than a specific regulatory compliance, may drive your need to know. In general we start with US DOT and UN Transport regulations in considering risks.

Q: I'd like to send a sample for testing

But I don't have an MSDS.
A: Whether you have an MSDS or not, do not send material without first obtaining permission from Stresau Laboratory to do so. That permission process will involve us getting your best information about the risks of the material.

But it does not have approved packaging.
A: For potentially explosive materials Stresau can provide special containers to ship up to 25 grams of uncharacterized material. For other hazards, such as oxidizers, organic peroxides, corrosive or flammable materials, Stresau will work with you, and in cooperation with DOT if appropriate, to assess the worst case scenario and the appropriate packaging and shipping options for sample transportation.

Q: The material is proprietary, what do you need to know about it and how will that information be protected?
A: Stresau Laboratory handles proprietary as well as classified material with procedures that protect both the material and the information relating to it. If you wish to send a non-disclosure agreement first, Stresau Laboratory will accept it.

Q: What happens to the sample material after the test?
A: The test material and associated packaging remains the property of the client and it is returned after the test. This insures you that your "cradle to grave" responsibility for hazardous materials is controlled by you.

Q: How long will the testing take?
A: Typical testing takes about two weeks from receipt of material to your receipt of a test report. The nature of testing and current commitments will influence that time and will be part of the discussion regarding what testing you need.

Q: Can Stresau Laboratory conduct testing at my location?
A: Yes. It is usually less expensive to test the materials at Stresau Laboratory but we have gone to locations either to characterized material too sensitive to ship or in cases where there are so many samples or real-time determinations make shipment impractical.

Q: What are the steps involved in testing?
A: Here are some of the steps involved in typical testing:

  • Discussion regarding what tests will result in a determination of how much sample material is required and how it will be packaged for shipment and for testing.
  • Stresau Laboratory's Safety Office will review the subject material and intended test and issue the client permission to ship. This is typically a same-day turn-around, however, some materials and tests can take longer.
  • Following receipt of materials, the tests will be scheduled and conducted. Clients are always able to witness any and all of their tests and tests schedules will accommodate your schedule if this is the case. Customers can also opt to have tests video taped.
  • A written test report is provided.
  • Test samples and relevant packaging and test fixtures will be properly packaged and shipped to client.
