PULHES is a United States military acronym used in the Military Physical Profile Serial System. It is used to qualify an enlistee's physical profile for each military skill . Each letter in the acronym (see box below) is paired with a number from 1 to 4 to designate the service member's physical capacity.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
The medical section of the SRP includes a series of medical examinations and evaluations consistent with the PULHES Factor rating scheme, which is used to qualify an soldier's physical profile for each military skill. PULHES stands for physical capacity, upper body, lower body, hearing, eyes, and psychiatric. [9]
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
PULHHEEMS is an abbreviation for the factors it is intended to test. These include: Physique Upper limbs Lower limbs (or 'Locomotion', as this includes the back) Hearing (right) Hearing (left) Eyesight right (corrected / uncorrected) Eyesight left (corrected / uncorrected) Mental function Stability (emotional)
Abrasion resistant steel is a high-carbon alloy steel that is produced to resist wear and stress. There are several grades of abrasion resistant steel, including AR200, AR235, AR400, AR450, AR500 and AR600.
For more severe corrosion conditions, when 304 stainless steel is too sensitive to pitting or crevice corrosion by chlorides or general corrosion in acidic applications, it is commonly replaced by 316 stainless steel. 304 and 302 stainless steels are subject to chloride stress fracture failure when used in tropical salt water conditions such as ...
