Applicazioni 11/15/2017 2.1 MB A drop tower can be used to measure energy absorbed of a sample or to apply a set amount of damage to a specimen at impact velocities from 1 – 24m/s. FTIR Analysis (ASTM E1252) can be used to identify the major polymer type. Rubber, plastic, and elastomeric material formulations can be greatly affected by a wide range of environmental conditions and physical forces. About Plastics Testing Polymers are utilized in virtually every facet of human activity and industry including packaging, automotive, electronics, healthcare, construction, and aerospace. Where applicable, ASTM specs are given as sources for more detailed information. Plastics Testing Methods: One common type of plastic test is a test of how the plastic holds up under different temperatures.  A batch of approximately 180 tonnes of collected plastic waste from households of Copenhagen was tested at the Augustine sorting facility in Germany as a part of Action 3.2. Deflection temperature (ASTM D648), melting point by DSC (ASTM D3418), thermal expansion by TMA (ASTM E831), filler content by TGA (ASTM E1131), and melt flow rate (ASTM D1238) tests all provide data for thermal characterization of plastic. This guide is designed to introduce you to the basic elements of an ASTM D790 flexure test, and will provide an overview of the testing equipment, software, and specimens needed. Values are taken at a certain temperature and with a certain mass applied, dependant on material. ASTM's plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives. Material specifications differ from test methods because test methods only specify how to test for a property but do not include acceptable ranges for the test results. We work closely with plastic industry stakeholders to maintain and enhance existing UL Standards, establish new Standards, and develop certification and testing programs that address emerging technologies and product applications. 2.

Whether regarding solids, powder or liquids, … Thermal testing consists of either measuring the HDT (Heat Deflection Temperature) or VICAT softening point. My questions are: 1. There are two types of instruments used to measure the rheological properties of plastics: melt flow testers and rheometers. Mechanical, thermal, optical, rheological behaviour and climate testing allow the developers to better understand their product, and introduce stronger quality control. Our decades of experience and wide range of testing instruments provide a unique advantage in finding the probable root cause for a failure. Testing plays a critical role in the life cycle of a polymer, from the raw material to the compound through to the semi-finished and finished product. A typical summary statement for a basic material identification report might read "The FTIR, EDS, and TGA analysis of the sample was consistent with that of a polycarbonate with 10% glass filler." Pipe systems made of thermoplastic polymers or fiberglass-reinforced plastics are mainly used for transporting water or gases and are subject to stringent quality requirements. Each stage has different test requirements, and each end user may require a different test solution depending on their role, whether it is in Product Development (R&D), Quality Control (QC), Testing Services (TS), or Research (R). Chemical analysis by FTIR (ASTM E1252), filler quantity by TGA (ASTM E1131), and multiple other tests allow us to verify that the material is within specification.

A constant load is then ap… That testing usually involves the use of a thermal chamber, but these can have drawbacks. Plastic used in electrical applications often requires testing such as Dielectric Strength (ASTM D149), Volume Resistivity (ASTM D257), or Surface Resistivity (ASTM D257). A melt flow test measures the melt flow rate (MFR) and melt volume rate (MVR) of a molten polymer. Typically, a few grams of a thermoplastic sample are heated and compacted inside a furnace, becoming a homogeneous fluid. Tensile testing of plastics supplies the data for a sample: – Tensile strength (maximum tensile stress) – Ultimate tensile elongation – Ultimate stress – Elongation at failure; It is also possible to determine the elastic modulus of a plastic material. A: Tensile testing is the most popular test for plastics because it yields so much critical data. Based in Grangemouth, UK, they have over 120 years of combined experience and 6 million hours of test data in this specialized field. We can also perform small-scale flammability tests as well as a variety of ignition, mechanical, electrical and short-term thermal tests, which can be used for application in other UL Recognized Components and Listed end products. Chemical testing of polymers and plastics is required to ensure that a material is suitable for its intended application. They tell you how to check tensile and flexural properties, stiffness, impact, hardness, flammability, etc. How to test Plastic Properties Here is a list of common test methods used to evaluate plastics. The range includes mechanical, physical and chemical tests of plastics. This seems like overkill provided we were told industry standard is cycle of 1. Sample Preparation Equipment is used to prepare samples to specific shapes before a mechanical test is performed. If the friction of a material is too high then the film may too ‘tacky’ for the process, too low and the film may be too ‘slippy’ for the process. Friction Testing. Material specifications list specific performance requirements for different grades of plastic. These tests are typically performed on flat plaques but a … Applicazioni 11/15/2017 2.1 MB TGA Analysis (ASTM E1131) can be used to quantify the inorganic fillers. Melt Flow Testing Due to the wide range of application areas and materials, there are numerous national and international standards relating to the testing of plastic pipes. Basic identification of plastic can be accomplished by using three analytical tests. Producing a film of a thickness less than the specification may result in the material not having optimum functionality within the end user application. There are a wide variety of tests used for mechanical testing of plastics but some of the most common are Tensile Properties (ASTM D638), Flexural Properties (ASTM D790), and Izod Impact Strength (ASTM D256). - Design & SEM by IMM-LLC. The brochure addresses the most prominent and widely-used standards in the materials testing industry for plastics. This combination of tests provides basic information but additional testing is needed if identification of a trace additive or the grade of plastic is required. Characterizing the thermal properties of plastic is important to make sure that it will process correctly and that it will stand up to the service temperature of your application. These specific traits make one plastic a more attractive design material than another, depending on how the … These tests are typically performed on flat plaques but a variety of shapes and sizes can be accommodated. Plastic used in electrical applications often requires testing such as Dielectric Strength (ASTM D149), Volume Resistivity (ASTM D257), or Surface Resistivity (ASTM D257). Chemical testing of a plastic or polymer material can be complex but can provide valuable information on the additives used … A pendulum tester measures the impact resistance of samples in various standard test configurations. USP Class testing is one of the most common methods of testing to determine bio-compatibility of materials.
