ASTM E1252 PDF

This Draft Uganda Standard, DUS , is based on ASTM E – . ASTM Standards volume information, refer to the standard’s Document Summary . Fourier Transform Infrared Spectrometry ASTM E, ASTM E FTIR can generate an infrared spectral scan of samples that absorb infrared light. Scope. ASTM E – FTIR ANALYSIS TESTING SERVICES – ASTM E is a method of identifying organic compounds by FTIR analysis.

Alkali halide pressed pellets, Attenuated total reflection spectroscopy, Diffuse reflection spectroscopy, Disposable IR cards, DRIFT spectroscopy, Emission spectroscopy, Gas chromatographic effluent spectra, Gas phase spectra, Heated gas cells, Infrared solution spectra, Infrared spectroscopy, Latex suspensions, Liquid phase spectra, Photoacoustic spectroscopy, Polymer analysis, Qualitative infrared analysis, Solid phase spectra, Split mull technique, Vapor phase spectra.

The resulting spectrum can be searched against a computerized database containing known spectra for thousands of organic materials. The mid-infrared region is from to wavenumbers, which equals wavelengths of 2. FTIR is also used for quality control of materials and for contamination analysis surface or internal.

Identify the primary component of a plastic, rubber, or organic material. Unknown spectral scans can be analyzed to determine the base material of the unknown by comparing their scan to spectral satm of known materials that are stored in a computer-based library. Your basket is empty. Auditing Consulting Sourcing Training. FTIR spectral subtractions are used zstm look for internal contamination in polymers.

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality aztm safety solutions to a wide range of industries around the world.

Once the solvent is evaporated off an FTIR analysis is performed on the solvent wash residue. Material testing you can trust since Astmm more about the cookies we use and how to change your settings.

Further identification may be aided by an Ash Test. Obvious surface contamination of polymers can be analyzed by e122 reflective FTIR because the infrared beam only enters a few microns into the sample surface.

A skilled FTIR analyst is needed to examine the computer selected spectral matches to ensure that sample identifications are both accurate and complete.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

This results in an FTIR spectrum without the minute details necessary to identify the unknown material. Enabling you to identify aztm mitigate the intrinsic risk in your operations, supply chains and business processes. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

ASTM E1252 – 98(2013)e1

Differences noted in a newly generated spectral scan could indicate a change in processing or a possible contamination problem. We use cookies to make our website easier to use and to better understand your needs.

This instrument transmits an infrared light through a sample and asmt the wavelength of the light as it records how much light is absorbed at each wavelength. Need help or have a question? If the material does not absorb infrared light a spectral scan cannot be obtained.

Validating the specifications, value and safety of your raw materials, products and assets. Standards can be obtained from appropriate standards authorities. Inspection Validating the specifications, value and safety of your raw materials, products and assets. FTIR can generate an infrared spectral scan of samples that absorb infrared light.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains e1225 business processes. Computerized spectral searches can quickly compare an unknown spectrum to a very large number of spectra located in multiple databases in a very short period of time.

A solvent wash involves using a solvent that f1252 nondestructive to the sample. However, an FTIR spectral scan alone should not be expected to identify the type of Nylon or Polyester, identify a Polypropylene or Acetal as a homopolymer or copolymer, or determine whether the Polyethylene is a high density or low density material. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. FTIR can identify the difference between materials, such ast, polypropylene and polyethylene, which are made of only carbon and hydrogen but have different types of bonds between the elements.

Samples, which can be easily tested by reflective FTIR, include polymer pellets, parts, opaque samples, fibers, powders, wire coatings, and liquids.

The objective is to look for material differences. Computer programs are very helpful for comparing unknown spectral scans to those of known materials, but computer selected matches can be misleading. Assurance Testing Inspection Certification.
