One of the major research aspects ofis physical and chemical testing; and its test findings are the primary scientific basis for assessing product quality. Physical and chemical laboratory experiments include three primarysystematic error, random error and human error. These sources of errors in lab should be studied well before any further action.
So, what are the particular sources of each error?
The reliability of physical and chemical testing has been significantly impaired; by equipment, samples, instruments, lab environment, reagents, operating procedures and other factors; leading to many errors in physical and chemical testing.
