Toyota case study powertrain

Learn why Toyota Motor Corporation chose to partner with GORE® Automotive Vents when other venting solutions could not meet Toyota’s performance requirements for a new e-axle containing lubricated gears and a higher-voltage e-motor. This Case Study outlines the associated challenges, solution and results — including an on-time product launch for Toyota.

NEMA Ratings and What They Mean

Technical Information

A critical aspect of vent selection begins with defining the level of protection your application, device or housing requires.

IP ratings cannot be “converted” to NEMA ratings, since NEMA requires additional testing not included in IP. However, there are minimum NEMA ratings that will meet or exceed a given IP code.

Materials Technology: IP Ratings — Ingress Protection Classification

This document explains the format and classification of Ingress Protection (IP) ratings, according to the IEC 60529 standards.

Materials Technology: UL 94 Standard for Flammability Testing

This document explains the Underwriters Laboratory standard for testing the flammability properties of plastic materials used for parts in devices and appliances.

Materials Technology: Water Entry Pressure Testing

Description of standard test used to measure a membrane's ability to stop aqueous flow, and diagram of the apparatus used for water entry pressure testing.

Materials Technology: Gurley Airflow Testing

Description of standard test used to measure airflow of low flowing media, and diagram of the apparatus used for Gurley airflow testing.

Materials Technology: Venting With Hydrophobic vs. Oleophobic Membranes

The key to choosing the appropriate membrane technology for a given application is understanding the environmental conditions and the surface tension of the fluids that the vent will encounter.
