IEC and ISO Test Methods Brochure

IEC and ISO Test Methods Be a part of the DOble difference! The goal of the Doble Materials Laboratory is to provide unsurpassed quality in the testing of insulating liquids and materials. In addition, we pride ourselves on the fact that we perform many of the complicated and non-routine tests that other laboratories do not even attempt to perform and do so at a reasonable price. We are pleased to announce that not only do we provide comprehensive testing according to ASTM procedures but can also provide testing to many IEC and ISO tests as well. Below is a listing of tests that can be performed.
