Category A is a dielectric rating of an aerial device. Commonly this is known as "barehand" unit rating. In order for a aerial device to be classified as Category A it must be equipped by the manufacturer with an on-board current meter in addition to modifications to the aerial which bond all parts of the machine together and to the chassis. The unit then also must be tested according to ANSI 92.2 2009 section 5 including a dielectric test to the qualification voltage. This is commonly 500 Kv, testing to this range of voltage is only done by select companies across the United States and must be maintained at the intervals in the ANSI standard. It is highly recommended to contact the manufacturer of the aerial device to verify whether the unit in question is equipped for Category A service. If not it can be added by the manufacturer retro actively but is a significant expense. If the equipment was manufactured with Catergory A dielectric rating the information about maintenance requirements will be in the maintenance manual. You can acquire a copy of an excerpt of the ANSI manual of responsibilities from the ANSI.org website, the scaffold industry or the manufacturer of the aerial device.
ANSI SQL is the American National Standards Institute standardized Structured Query Language. ANSI SQL is the base for several different SQL languages such as T-SQL and PL/SQL. ANSI SQL is used to Create, Alter, and View data stored within a database. For more information about ANSI: http://www.ansi.org/ For more information about SQL: http://en.wikipedia.org/wiki/SQL
It is the abbreviation for Steam Working Pressure.

Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.
It's #150.
No. The answer is same as class 150
If the pressure exceeds the normal rating of the fittings and valves.. Normally rated for 125 PSI
Its d schedule rating of pressure of pipe...
Water is in the liquid state at 125 degrees Celsius, unless kept under pressure.
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
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.
A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
NPT Pressure stands for National Pipe Thread Pressure, which refers to the pressure rating of a pipe thread. This rating determines the maximum pressure that the pipe thread can safely withstand without failure. It is important to match the NPT pressure rating with the pressure requirements of the system to prevent leaks or ruptures.
