Hard Hat - Standards

Standards

In 1997, the American National Standards Institute revised its performance standards for hard hats. What exactly the standards are is not publicly disclosed except to paying members. Conformity to these standards and regulation are not necessary but almost all manufactures comply:

  • ANSI Type I / CSA Type 1 hard hats meet stringent vertical impact and penetration requirements.
  • ANSI Type II / CSA Type 2 hard hats meet both vertical and lateral impact and penetration requirements and have a foam inner liner of expanded polystyrene (EPS).
  • A Class E hard hat has been proof-tested to insulate up to 20,000 volts of electrical potential.
  • ANSI have compliance for hard hats and their combustibility or flammability criteria.

Famous quotes containing the word standards:

    In this nation I see tens of millions of its citizens, a substantial part of its whole population, who at this very moment are denied the greater part of what the very lowest standards of today call the necessities of life. I see one third of a nation ill-housed, ill-clad, ill-nourished. The test of our progress is not whether we add more to the abundance of those who have much, it is whether we provide enough for those who have too little.
    Franklin D. Roosevelt (1882–1945)

    The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    To arrive at a just estimate of a renowned man’s character one must judge it by the standards of his time, not ours.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
