	Salt Spray Testing Machine Purpose: To duplicate the field corrosion performance of a product. The Salt Spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability for use as a protective finish. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.
	Environmental Testing Simulates different climate conditions to test if the product will operate to it’s specification under high or low temperature and humidity.
	DASS Testing Machine Purpose: Product QC All finished products before packing must be tested by the DAAS-L system, including frequency response, phrase response, impedance and harmonic distortion to confirm they meet all design specifications.
	Power Test Purpose: Check product reliability All amplifiers are age tested according to IEC268-1 standard. Electric power capacity of 200KVA let’s the product work continuously at its rated power to confirm it meets all the design specifications.
	Transducer Life Testing Purpose: Check product reliability The performance of all transducers is tested using Pink Noise at full working loads for 100 hours The transducer has to meet the design specification after this test.
