Testing Equipment #3200169

The Free Falling Dart Impact Tester is used for PVC pipes, PVC ducting pipes & HDPE pipes as per IS & DOT specifications.

The impact properities of the polymetric materials are directly related to the overall toughness of the materual. Toughness is defined as the ability of the polymer to absorb applied energy. The area under the stress-strain curve isdirectly proportional to thetoughness 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.

The Emitter Flow Rate Variation Tester is designed to determine the mechanical and functional requirments of irrigation emitters, and the data to be supplied by the manufacturer to permit correct installation and operation in the field. The appartus confirms toIS-13487 : 1992 standard.

It applies to emitters, with or without pressure regulation, intended for irrigation; It does not apply to emitters which form an integral part of the pipe during manufactur as well as microtubes.

The friction tester is primarly designed to determine the Co-Efficient of Friction of Plastic films, sheets, laminate, pipes and paper etc. The equipment provides the measurement of static and kinetic co-efficient of friction. The apparatus conforms to BS 2782 and ASTM D-1894 and other equivalent standards.

Measurement of frictinal properites may be made on a film or sheeting specimen when sliding over itself of over another substance. The co-efficient of friction arer related to the slip properties of plastic films that are of wide interestin packaging application.These methods yield empirical data for control purposes in film production.Correlation of test results with actual performance can usually be established.

The Carbon Black Content Tester has been designed incorporating many features and new ideas. The apparatus conforms to the most generally recognised National & International standards including BIS, IS, ASTM etc.

To determine the average of carbon black content especially in polyethylene materials by pyrolysis method, like plastic pipes, films, sheets, cables, water tanks etc, this equipment is very much useful for evaluation of Carbon Black Content. Carbon Black is used in plastic as UV stabilizer to prevent degradation of plastic by UV radiation. It is also possible to find out ash content in plastic material by this instrument.

The UNIVERSAL TENSILE TESTER is used for determining the ability of the material to withstand forces that tend to pull it apart & to determine to what extent the material stretches before breaking.

Different type of plastic materials are often compared on the basis of TENSILE, FLEXURAL STRENGTH, ELONGATION, & TENSILE MODULUS DATA. Many plastics are very sensitive to the rate of straining and environmental conditions. The tensile property data are more useful in preferential selection of a particular type of plastic from a large group of plastic materials.

Tests for tensile strength (stress at fracture of the specimen) and elongation (extension of material under load of plastics. The first provides a measure of the breaking strength of the material but is radically affected by the rate of loading and the ambient temperatuere. Tensile strength in kgf/cm sq. = load (kgf) / a x b (cm sq.) Elongation % = (L2-L1) x 100/L1. Standard test methods : BS 2782 method 301, ASTM D 638, ISO R527.

The Carbon Black Dispersion instrument is used to find out the dispersion of additives e.g. pigments, fillers in plastics. In plastic material, pigment and fillers play a very important role for matching the uniform colors as well as resistance against UV light.

This equipment is also useful for determination of surface defects, voids, bubles, filler distribution & other structural investigation.
