Toyota wants to salute do-gooders by giving 100 cars over 100 days to organizations that could really use a new set of wheels. And voters like you decide who gets a new ride every day.
PEI is the abbreviation for Porcelain Enamel Institute. A PEI Rating is given to a tile product based the hardness of its glaze. This hardness is determined by the manufacturer using a standardized test.
The PEI rating only refers to a tileâs strength and suitability for a particular application; it is not an indicator of the tileâs overall quality or value. In many cases, some of the most beautiful and costly tiles have a PEI 1 or 2 rating.
