Knowledge of the properties of plastics is essential for designing products, specifying the material to be used, carrying out quality control on finished products, failure analysis and for understanding the structure and behaviour of new materials.

Each class of materials has its own specific test procedures, which have developed as the material has evolved. This book concentrates on one area of testing – short-term mechanical tests. These are defined as tests of mechanical properties where the effects of long periods of time and cycling are ignored. This group of tests includes hardness, tensile, compression, shear, flexing, impact and tear and in this book it is also taken to include density and dimensional measurement together with test piece preparation and conditioning.

The topics covered in this book, include:
1. Introduction
Reasons for Testing, Source and Condition of Test Pieces, Test Conditions, Limitations of Results, Sampling, Standards, Quality Control of Testing, Test Equipment, Product Testing, and Modes of Stressing.
2. Test Piece Preparation
Mixing, Moulding, Stamping from Sheet or Film, and Machining.
3. Conditioning
Storage, Conditioning, Heat Treatment, Mechanical Conditioning, Test Conditions, and Apparatus for Conditioning.
4. Mass, Density and Dimensions
Measurement of Mass, of Density, and of Dimensions.
5. Hardness
Relationships, Standard Methods, and Other Methods.
6. Tensile Stress-Strain
General, and Test Methods.
7. Compression Stress-Strain
Test Apparatus, Standard, and Other Tests.
8. Shear Properties
Standard, and Other Tests.
9. Flexural Stress-Strain
General, and Test Methods.
10. Impact Strength
General, and Specific Tests.
11. Tear Properties
Test Piece Geometry, Standard, and Other Tests
12. Fracture Toughness
Standard, and Other Methods.
This book will be useful to all those who are already involved in the testing of polymers and it is an ideal guide to those just starting out in the field, whether in academia or industry.
