Results of these iron studies tests may mean the following: 1  A low serum iron level and low serum ferritin level may be caused by iron deficiency anemia. 2  A high TIBC and low serum iron level may be caused by iron deficiency anemia, pregnancy, and chronic blood loss. A low TIBC and high serum iron may be a sign of sideroblastic anemia (a condition that prevents your red blood cells from using iron). 2  A high serum ferritin level, high serum iron, and low TIBC may be caused by hemochromatosis.
Wash the surface only of the felt item if it is only slightly dirty. Be sure the felt is completely dry and use a soft-bristled brush to brush away any debris. Slightly dampen a clean cloth with cool water and gently wipe the surface to clean it. 3. Wash the entire piece by hand if surface washing is not enough. Dry brush any loose dirt off of the felt. Fill the sink with cool water. Soak the felt item in the water for a few minutes, then gently squeeze the water out of it.
F-13 and F-15 are low density felts with a wide range of uses where resistance to. abrasion, durability, and wear are not important factors. Typical uses include: sound deadening; chassis strips; spacers; dust shields; pedal pads; dash liners; fuel oil filters; anti-rattle. applications; grease and oil retention.
