PL8502	PLASTICS TESTING I	LPTC

3003

OBJECTIVES:

• To develop the knowledge of National & International standards for testing methods.
• To create the knowledge about the different testing techniques and its basic concepts for evaluating the chemical, mechanical, electrical, optical, thermal, and permanence properties of plastic materials.
• To enable the students to identify and compare the properties of different plastics materials.
• To enable the students to learn about the property of the plastic material for several

UNIT I	TESTING STANDARDS	5

Importance of testing, Standard and specifications- National and International standards-BIS, ASTM, ISO,BS,DIN,JIS etc- Laboratory accreditations – NABL, NABCB, APLAC etc.

UNIT II	IDENTIFICATION OF PLASTICS	9

Identification of plastics by simple methods e.g., visual inspection, density, effects of heat, combustion and solvents analysis, melting & Softening point, elemental analysis, confirmation test- analytical techniques used for identification and quantification of additives and fillers.

UNIT III	TESTING OF MECHANICAL PROPERTIES	12

Preconditioning and test atmosphere, Specimen preparation techniques – Moulding, Contour cutting, contour punching, etc. Techniques for testing of Short term mechanical properties of Plastics – Stress – Strain curve, toughness, brittle and ductile nature of materials, Tensile, Flexural, Compression, Shear, Impact strength, Tear, abrasion, Hardness and friction test.

UNIT IV	TESTING OF THERMAL AND OPTICAL PROPERTIES	10

Techniques for testing of Thermal properties – Melting Point, Specific heat capacity, HDT, VSP, Flammability (Rate of burning, UL 94, LOI ), Ignition properties of plastics.Thermal conductivity, Coefficient of Thermal Expansion, Brittleness Temperature Optical properties – Luminous transmittance, Haze, Specular Gloss, Refractive Index, colour measurement, optical microscopy

UNIT V	TESTING OF ELECTRICAL AND FLOW PROPERTIES	9

Techniques for testing of Electrical properties – Surface & Volume Resistivity, Arc Resistance, CTI, Dielectric Strength, Dielectric constant and Dissipation factor- Rheological properties – Melt flow Index, Melt viscosity (as function of temperature and shear rate)

TOTAL : 45 PERIODS

OUTCOMES: Upon completion of this course,

• Students will learn how the plastics materials are tested for its chemical, mechanical, electrical, optical, thermal, and permanence properties.
• Students will be able to identify the plastic materials for some specified applications based on its property.
• Students will able to understand the basic principle of polymer testing machines.
