The ductwork airtightness level is the airflow rate through ductwork leakages divided by the ductwork area. It is recommended to test at least 10% and 10 m 2 of the duct surface including all duct types and a variety of sizes and components. The ductwork surface area is estimated according to EN 14239.
Therefore, minimizing duct pressure drop by minimizing turbulence at elbows and transitions is of importance. Duct elbow radius is usually 1 1/2 to 2 times the duct size. The side slopes of transitions are typically 10 to 30 degrees. Note: the duct gas velocity is chosen to minimize duct dust dropout.
Shoes with a variety of toe boxes. The toe box is the section of footwear that surrounds the toes on closed-toe shoes. [1] Toe boxes that are too tight can cause injuries and foot deformities, whereas wider toe boxes may be used to treat or prevent common foot conditions such as broken toes, [2] [3] bunions, [4] [5] and Morton's neuroma.

A duct with less than 0.75 mg/100m 2 is considered to be clean, per the NADCA standard. [7] A Hong Kong standard lists surface deposit limits of 1g/m 2 for supply and return ducts and 6g/m 2 for exhaust ducts, or a maximum deposit thickness of 60 μm in supply and return ducts, and 180 μm for exhaust ducts.
