How is oxidation time measured in induction?
OIT measurements are commonly carried out using differential scanning calorimetry by temperature programming the specimen in an open sample pan from ambient to a test temperature under an inert atmosphere.
What is oxidation induction test?
The Oxidation Induction Times Test (OIT), as carried out in a differential scanning calorimeter (DSC), is used to predict thermo-oxidative performance of a material. Samples are heated up under a nitrogen atmosphere, typically to 200C.
How can the oxidation induction time OIT specified in the DSC be used in industrial purposes?
Oxidative Induction Time (OIT) measured by Differential Scanning Calorimetry (DSC) on molten polymer samples is widely used in the plastics industry to assess the thermal stability of polyolefins. It is simple, it requires small samples and it is relatively fast.
What is induction time and why is it important?
Induction time refers to a period of time that is necessary to initiate a reaction. Induction time allows a chemical reaction to reach a necessary stage. In paint, it is the duration that must elapse after mixing fresh paint material before starting a satisfactory application.
What is OIT in DSC?
Oxidation induction time or OIT is a standardized test performed in a DSC which measures the level of thermal stabilization of the material tested. The time between melting and the onset of decomposition in isothermal conditions is measured. The atmosphere is nitrogen up to melting and then oxygen.
What is OIT in HDPE?
Oxidation Induction Time ( OIT ) The measurement is carried out in an oxygen atmosphere at a temperature that is sufficiently high (usually at 200-210 oC for polyethylene materials) to assure that decomposition begins within a reasonable time.
What is the induction time?
The induction time is defined as the time interval between to the formation of an appreciable amount of the solid phase and the initial moment of supersaturation of the solution.
What is oxidation onset temperature?
Oxidative-Induction Temperature (dynamic OIT) or Oxidative-Onset Temperature (OOT) is a relative measure of the resistance of a (stabilized) material to oxidative decomposition, determined by calorimetric measurement of the temperature at the beginning of the exothermal oxidation of the material, which is exposed to an …
What makes a good induction?
What Makes an Induction Program Successful? Effective inductions are timely, organized and engaging, and give a good first impression of a company.
What is the full form of OIT?
OIT – Office Of Information Technology.
What is epoxy induction time?
In fact, many epoxy materials have what is known as an “induction time,” or “sweat-in time,” where the coating is mixed and allowed to react for a period of time (e.g., 30 minutes) so that cross-linking of the components can initiate prior to application of the product.
What is heat flux DSC?
Heat Flux DSCs A technique in which the temperature of the sample unit, formed by a sample and reference material, is varied in a specified program, and the temperature difference between the sample and the reference material is measured as a function of temperature.
How long should a work induction take?
The induction phase has no set period and varies according to the new employee’s role and the company they will be working for. It could last just a few hours, a day or two or even a week.
How long is a work induction?
Induction usually only takes about 2 hours and if your induction is on Saturday then your first official shift would most likely be Sunday. The induction would take an 30 minutes max. Once you have your induction you could possibly start from 7days after maybe sooner maybe longer.
How can we make induction more successful?

What does IoT stand for?
Internet of Things
The term IoT, or Internet of Things, refers to the collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves.
Why does induction take so long?
The amount of cervical ripening and preparation can influence the length of an induction. If you are being induced and have a low bishop score, and need quite a bit of cervical ripening, you can expect your induction to take much longer.
