Unit- full form and description

Unit Full form Description    
 lb, lbm, lbm, ℔ Pound The pound or pound-mass  is a unit of mass used in the imperial, United States customary and other systems of measurement. 1 Pound=0.45359237 kilograms,  
psi Pound per square inch A unit of pressure    
 mpa  megapascal
Megapascal is a metric system pressure unit and equals to 1 000 000 force of newton per square meter. The abbreviation is “MPa“.
megapascal (MPa) is a decimal multiple of the pascal, which is the SI derived unit of pressure, stress, Young’s modulus and ultimate tensile strength. It is a measure of force per unit area, defined as one newton per square meter.

Convert megapascal [MPa] <—> newton/millimeter² [N/mm² ...

 
 atm  Standard atmospheric  (symbol: atm) is a unit of pressure.Atmospheric pressure is the force per unit area by the weight of air above that point.  1 Atm = 0.101325 Megapascals

defined as 101325 Pa (1.01325 bar), equivalent to 760 mmHg (torr), 29.92 inHg and 14.696 psi.

 

 
 N     

Newton: 1Newton in Earth gravity is the equivalent weight of 1/9.80665 kg on Earth. This is derived using Newton's second law f=ma and assuming Earth gravity of 9.80665 m/s2. 1 N (Earth) = 0.101971621297793 kg.

Guage: Metal sheet thickness-

 Guage is a Unit of thickness of a metal sheet or wire represented, in a retrogressive scale (higher numbers mean lower thickness)For sheet: For sheet metal,  that starts with 10 gauge representing a thickness of 3.416 millimeters or 0.1345 inches. As the gauge number increases, the thickness drops by 10 percent. For example, a 12 gauge sheet is 2.732 millimeters thick, and a 13 gauge sheet is 2.391 millimeters thick.
For wire thickness there are two scales, see American wire Gauge for the first one. The second is a metric scale in which a gauge number is equal to 10 times the diameter of the wire in millimeters. For example, a 5 gauge wire is 0.5 millimeter in diameter and a 6 gauge wire is 0.6 millimeter in diameter. Also spelled as gage.Instrument with a graduated dial or scale used in measuring a dimension or quantity or for establishing mechanical accuracy.Read more from  businessdictionary

Fire-resistance rating :

A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail a host of other criteria, involving other evidence of functionality or fitness for purpose.

STC Rating

STC stands for Sound Transmission Class.Basically, STC ratings are an established way to average how much sound is stopped by something. STC ratings are used for windows, doors, walls and most building materials. For windows, STC ratings range from 18 to 38.

STC ratings are the ONLY way to accurately compare various noise reduction products. An STC rating is an instrument measurement of how much noise is stopped. The STC ratings allow accurate ‘apple to apple’ comparisons.

The STC rating is the average amount of noise stopped at 18 different frequencies, measured in decibels. STC ratings are a logarithmic scale similar to the earthquake Richter Scale, which means each number is significantly higher than the one before.
