*A grit size is defined by the distribution of grits retained on a sieve set up that meets the requirements of ANSI Table 2 or 3. The numbers in the two sieve columns in this chart represent the midpoint sieve for the grading of the corresponding grit size.

In Europe, the FEPA had its own metric grit-grading system. FEPA-graded paper carried a P prefix in front of the grit number. Today that's not always the case. Now that most manufacturers have switched to the FEPA-grading system, the letter P isn't always stamped on the paper.

To fully understand the system, you'll want to research the documentation provided by the ANSI as described below (ANSI B16.5). It's dozens of pages long and cannot be expressed in just a few paragraphs. ANSI CLASS INTRO. ANSI stands for American National Standards Institute…

ANSI GRADE The American Nation Standards Institute (ANSI) grading system for deadbolts was developed by the Builder's Hardware Manufactures (BHMA). This grading system ranges from 1 (the highest grade) to 3 (the lowest grade). It factors in longevity of the lock, toughness, and latch length.

The Different Types of Lock Grades. There are three different lock grades, which include:. ANSI Grade 1 - This is a heavy-duty commercial security lock. It is specifically designed for high traffic and superior security. As the strongest grade, it can be used for residential applications too, but it is predominantly found in commercial and industrial applications.

The American grading system called Cami is not used as widely. Cami is identified by just the number (24 coarse – 1200 super fine). The difference is that the Cami grade is coarser than the P grade in coarse grits and finer than the P grade in the finer grits. The comparison chart is used to help transition and use between the 2 systems.
