What is it?

Tesla’s TP -0000808 standard provides guidance on how to evaluate different materials, components and assemblies that are exposed to a corrosive environment. Tesla’s cyclic standard comprises of (3) conditions

• Salt Application

• Dwell Phase

• Humidity portion

These conditions are involved in mostly all cyclic exposure tests to try to mimic real world conditions.

Salt Type:

Tesla’s TP-0000808 has (2) options for salt exposure. Depending on where the vehicle will be located. Each solution comprises of different chemicals. This information is needed prior to testing.

How do I know which exposure to test to?

Within the standard they have different vehicle types and also different exposure zones. Examples are Exterior, Under hood, and Interior to name a few. Please consult with your engineer to establish the correct exposure.

Test Cabinet:

Assured Testing has multiple exposure cabinets that can meet these conditions within the standard. Currently (20) cyclic cabinets are available that can perform in accordance with the Tesla TP-0000808 Standard.

How long is the test?

As mentioned above the cyclic test for Tesla TP-0000808 depends on the location of the sample. Samples for underbody and exterior generally are exposed to longer durations. Which makes sense as they are exposed to real world conditions. Interior components are exposed to a lesser duration in Tesla’s TP-0000808 as they do not see these extreme environments.

Per the test cycle in Tesla TP-0000808 the weekends do not count. Meaning a 90 cycle test will take 126 days to perform.

Preconditioning of the samples:

Depending on the location of the samples on the vehicle, they maybe exposed to chipping resistance to SAE J400. This test was designed to emulate gravel hitting the underbody or exterior of the car. Following testing the samples will be evaluated in this area.

All samples regardless of exposure area will be scribed and evaulated to ASTM D1654 at the conlusion of testing.
