PPAP is integral to the IATF16949:2016 Quality System. It defines generic requirements for production part approval. It ensures that parts manufacturers, like Gore, document our capability to consistently meet your product specifications when manufacturing that product at quoted production levels.

At Gore, our commitment is to deliver products that meet our customers’ expectations and are fit for their intended end-use. We commit to every customer that “our products will do what we say they will do" — and we stand behind that promise with our worldwide resources, expertise, and quality processes.

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.

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

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

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.
