Following is a partial list of the testing procedures and performances criteria required by the Minimum property standards. It is important to ask your licensed contract if you have any questions in regards to these standards.
WALL ASSEMBLIES AND SHEATHING MATERIALS – RESISTANCE TO RACKING
Test Procedures. Test of Walls shall be conducted in accordance with ASTM E 72-80, “Standard Methods of Conducting Strength Test of Panels for Building Construction.” Panel size shall be eight feet by eight feet
Dry Test: Load increments – 400 lb; Maximum load – 5200 lb or 0.65 kips/ft; At load of – 1200 lb average total deflection 0.20 in. Residual deflection 0.10 in.; At load of – 2400 lb average total deflection 0.60 in. Residual deflection 0.30 in.
Wet Tests: Load increments – 400 lb; Maximum load – 4000 lb or o.50 kips/ft; At load of – 1200 lb average total deflection 0.28 in. Residual deflection 0.44 in; At load of – 2400 lb average total deflection 0.80 in. Residual deflection 0.40 in.
DOORS, WINDOWS AND GLAZING
WINDOWS AND SLIDING GLASS DOORS – AIR INFILTRATION
Test Procedure. Air leakage shall be tested in accordance with ASTM E 283-91
When tested at a static air pressure of 1.567 psf, the rate of air leakage shall not exceed 1/2 cfm per ft of crack length. Air leakage for jalousie windows is not to exceed 1 1/2 cfm per sq ft of total ventilating areas. Air leakage for sliding glass doors is not to exceed 1 cfm per sq ft of overall frame dimension.
In areas subject to winds (90 mph and over) the performance requirement for sliding glass doors may be increased at the discretion of the HUD Field Office so that the air leakage will not exceed 1/2 cfm per sq ft of overall frame dimension.
WINDOWS AND SLIDING GLASS DOORS – WATER RESISTANCE
Test Procedure. Water infiltration shall be tested in accordance with ASTM E 331-86.
Minimum Performance – No water shall pass the interior face of t he unit when tested at a static pressure of 2.86 psf with water applied at the rate of 5.0 U.S. gal per sq ft per hour for a time period of 15 minutes.
In areas subject to wind driven rain (90 mph and over) the static pressure from above may be raised to 6.24 psf at the discretion of the HUD Field Office.
WINDOWS AND SLIDING GLASS DOORS – PHYSICAL LOAD
Test Procedure. Physical load tests shall be conducted in accordance with ASTM E 330-90
Under a uniform load of 10 psf applied to surface unit, except jalousie windows and sliding glass doors, max deflection of any member shall not exceed 1/175 of its span
Under a uniform load of 20 psf applied for 10 seconds to the ext., then a uniform load of 10 psf applied to the int for 10 seconds, there shall be no glass breakage, damage to hardware or residual deflection
In areas subject to winds 90 mph and over, the uniform loads, show in above may be increased to 40 psf exterior and 20 psf interior loadings, at the discretion of the HUD Field Office.
