ASTM D150 Dielectric Constant and Dissipation Factor
Determination of Dielectric Constant (DC) and Dissipation Factor (DF) of insulating materials is done as per ASTM D150, IEC 60250 test method. DC and DF measurement by ASTM D150 can be conducted anywhere between the frequency values of 10Hz and 2MHz range as per the client’s requirement.
ASTM D150, IEC 60250 test method is used to measure Dielectric Constant (DC) and Dissipation Factor (DF) values for insulating materials. DC is the ratio between capacitance induced by two metallic plates when an insulator is kept between them, and the capacitance induced by the same plates with air or a vacuum filled in the space between the plates. Materials with low DC value make good insulators. A material with a higher DC value is used in high capacitance electric applications.
DF is the reciprocal of the ratio between the capacitive reactance and resistance of insulating material at a specified frequency. It is an indicator of the inefficiency of insulating material.
In the ASTM D150 test method, a specimen is kept between two metallic plates of the measuring device, and capacitance is measured. This activity is repeated without placing the specimen between the two electrodes. The ratio of these two values is calculated as the dielectric constant.
A flat specimen, larger than circular electrodes with a diameter 50 mm (2 inches), is used for the measurement for the ASTM D150 test method.
Dielectric constant (DC) = Observed Capacitance (Material as dielectric)/Observed Capacitance (Air or Vacuum) as dielectric.
Hence, ASTM D150 testing standard sets forth standard test methods for the determination of the AC loss characteristics and permittivity of solid electrical insulation.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
