Deepak Free Falling Dart Impact Tester is used for PVC pipes, PVC ducting pipes & HDPE pipe as per IS, DIN, ASTM, BS, DOT specifications.

The impact properties of the polymeric materials are directly related to the overall toughness is defined as the ability of the polymer to absorb applied energy. The area under the stress-strain curve is directly proportional to the toughness of a material. Impact strength is a measurement of toughness. The higher the impact strength of a material the higher the toughness and vice-versa. Impact resistance is the ability of a material to resist breaking under a shock loading or the ability to resist the fracture under stress applied at high speed.

Deepak DWT accelerated weathering tester is a laboratory simulator of the damaging effects of weather. It is used to predict the relative durability of materials exposed to the outdoor environment. Rain and dew are simulated by a revolutionary condensation system. The damaging effects of sunlight are simulated by fluorescent UV lamps. Exposure temperature is automatically controlled, as the daily sequence of UV periods and condensation periods. Testing duration of deterioration effect can be reduce by DWT which may occur in a longer period like a month or years of outdoor exposure. Deterioration observed includes fading, chalking, cracking, crazing, hazing, blistering, gloss lose, strength lose, and embitterment.

It is used to determine ballastic tearing strength and work factor of fabrics elmendorf method, supplied with calibration weights and augmenting mass to test upto 6400 gms. This test method has been widely used as one index of the tearing resistance of plastic film and sheeting used in packaging applications. While it may not always be possible to co-relate film tearing data with its other mechanical properties. This test method provides a controlled means for tearing specimens at straining rates approximating some of those found in actual packaging services.
