Tensile testing of flexible plasticyne products to ASTM D638

The following article demonstrates the diversity of the Universal testing machines manufactured by Tinius Olsen.

Recently we were approached by a leading Plastics packing company - RAK Petropack in Ras Al Khaimah, UAE to provide a testing solution for their plastics lab.

We supplied them with a complete testing solution as detailed below:

1. Tensile testing for flexible plastic sheets from 100 to 150 microns thick,
2. 90 degree Peel Testing with moving Base Sledge,
3. Coefficient of friction testing to ASTM D1894/ BS 2782 Part 8
4. Falling dart Impact Test,
5. Haze and Gloss measurement
6. Other instruments such as ovens, weighing scales and thermometers.

The following video is a demonstration of a live sample being tested:

Dumbbell Press & Cutters

Product: Dumbbell Press & Cutter
Use: Specimen cutting

During Materials Testing, how we prepare & cut the specimen plays a vital role in attaining accurate results. Different standards specify different dimensions for the sample cutting such as ASTM, ISO, BS, DIN, GOST etc,. Each standard  has various types for eg. TYPE I, TYPE 3, TYPE 1B etc

Tinius Olsen offers a wide range of Press & Cutters to meet  sample preparation requirements as per international standards.

.

Tinius Olsen hand operated cutting presses are specifically designed for the 'pressing out' of test specimens from sheet materials.

All presses are bench mounted and can accept a variety of different die cutters.

Various capacities are available ranging from 7.5KN, 15KN, 25KN

Tinius Olsen cutters are used to create accurate samples that help assure accurate, repeatable test results.

All die cutters are manufactured from high carbon steel, specifically hardened for long life.

Any shape available for specimens in accordance with standards such as ASTM D412, ASTM D638, ISO 527 (All Types) &  various ASTM, BS ISO, DIN, GOST, ISO.

Tinius Olsen cutting press are mainly used by commercial labs and manufacturers in UAE.

The following users are happily using Tinius Olsen cutters for sample preparation:

- Material Lab, Exova, Al Hoty Stanger, Specialty Chemicals, National Petroleum to name a few.

Plastics Testing in the U. A. E

Plastics in general are finding applications as replacements for metals and timber in a wide variety of industries.

The reasons for this are numerous and range from insulation properties, colour capabilities, molding capabilities to availability and cost.

As such, the testing of different plastics combinations has been, and indeed still is, been subject to rigorous control.

Today greater emphasis is being placed on the structural use of plastics and so there is an increased awareness of the need to test. Compounders, as well as processors require more stringent control of quality of both materials and processes to meet customer requirements.

This is especially true of critical component parts in the automotive, medical, aerospace and appliance industries. Some of the various tests possible on Tinius Olsen machines are: Tensile Rigid Plastics –

• ENISO 527,
• ASTM D638,
• BS6319, 2782,
• DIN 53455

Compression Rigid Plastics –

• ISO 604
• ASTM D695

Flexure Rigid Plastics –

• ENISO 178
• ASTM D790
• BS 782, 2782
• DIN 53452

Melt flow index of polymers –

• ASTM D1238
