ASTM C871 Chemical Analysis
Minimum 100 grams of full cross section of material, including all facing

ASTM C1617 

Single ASTM C871 Chemical Analysis Included in Testing. 

Tutco  developed this test method for ASTM. The method evaluates the effect of  extraction solutions or prepared corrosive solutions on 1) various  metals and alloys 2) protection measures such as protective coatings.  The procedure uses controlled reproducible conditions allowing the  comparison, and measurement of corrosion. The accelerated conditions  used produce a situation which may simulate the effect of many years of  exposure in a matter of days, producing thousands of wet/dry cycles.  Please contact Tutco for more information about the test method and so  we can discuss the particular test application and approach needed to  develop corrosion answers for your company.

RESEARCH & DEVELOPMENT

Tutco  has years of experience working with our clients on research and  development for their thermal insulation or related materials. Many have  been eventually brought to market.

We  are able to modify test procedures to test: 1. Other Metals 2.  Protective Coatings 3. Cements and Non-wicking Materials 4. Various  Corrosion-causing Liquids 5. High Temperature Exposure 6. Adhesives. We  are able to modify ASTM C692 and ASTM C1617 as well as other thermal  insulation tests.

We've  also developed and performed bench marking programs, worked with  specification development, and test method development. Please contact  us to see what we might be able to help you do.
