Steel toe shoe rating that is related to the force per square inch capacity that the steel toe can withstand.

ANSI is the American National Standards Institute. They coordinate the development of US Voluntary National Standards in private and public sectors with regards to information management and data communications. ASTM is the American Society for Testing and Materials. They develope, publish standards, definition of materials, methods for testing materials, installation practices and specifications for materials. Ok since ASTM develops the standards how does that affect OHSA standards to ANSI on safety ie.. Z87 stamp on safety glasses?
ANSI stands for "American National Standars Institute"
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
The latest ANSI standard is C99. See the attached link.

It's #150.
np40 is equivelant to ansi 300#
75 psig For pipe flanges the class rating is the pressure rating for the flange, in pounds per square inch - gauge (psig).
As of March 2005, ASTM F2413 standard superseded the ANSI Z41 standard. Manufacturers and distributors will implement a "running change" to their inventory from the ANSI Z41 labeled footwear. Because there is no change in the protocol, the ASTM F2413 standard does not require that the change from ANSI to ASTM labeled footwear occur in a specific time period.The protective footwear you choose must comply with the American Society for Testing and Materials (ASTM) standard F2413-05, formerly the American National Standards Institute's (ANSI) standard Z41-1999. The F2413-05 standard separates safety footwear into different categories such as Impact and Compression Resistance.ASTM F2413-05 - The letters F2413 reference the performance requirement for foot protection. The additional digits following the standard designation indicate the year of the standard to which the protective footwear complies, for example: 05 refers to 2005.M = Footwear designed for a male.F = Footwear designed for a female.I/75 = Impact rating of 75 (foot pounds)C/75 = Compression rating of 75 (2500 lbs. of pressure)The ASTM F2413 standard has two classifications for compression ratings 75 = 2,500 lbs and 50 = 1,750 lbs. This means the footwear has been tested to withstand compressive loads up to the designated number of pounds before the toe-cap will start to crush or crack.
one that has the right rating (ANSI, Snell, CEN...)the one out of those with the right rating that wits your head the best. No use going for a "better" helmet if it doesn't fit.
Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.

Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
Yes, if you have an ANSI C++ compiler. Most modern compilers are ANSI, and are capable of suppressing non-ANSI code, using a compiler option.
Lumen is a simple way to indicate the amount of light the projector has to produce the brightness of the picture. The higher the number the brighter the picture.
