Spectrographic Product Analysis
Spectrographic Product Analysis is a precise method used to determine the elemental composition of metals and alloys. By analyzing the spectrum of light emitted from a sample when it is excited by a high-energy source, this technique identifies the presence and concentration of specific elements. For engineered fasteners, this ensures that the material conforms exactly to the required alloy or specification, which is critical for strength, corrosion resistance, and performance.
How the Test is Performed
Sample Preparation – The fastener or material sample is cleaned to remove contaminants such as oils, coatings, or dirt.
Excitation – The sample is exposed to a high-energy source (often an electrical spark or arc) that excites the atoms in the material.
Spectral Measurement – The emitted light is captured and analyzed using a spectrometer to determine the types and concentrations of elements present.
Comparison to Specifications – Results are compared against the required alloy or material specification to verify compliance.
Documentation – Data is recorded and retained for traceability and quality assurance.
Why It is Performed
Spectrographic Product Analysis is performed to ensure that materials meet strict chemical composition requirements, which directly affect mechanical performance, corrosion resistance, and reliability. This test prevents the use of incorrect or substandard materials that could compromise the safety and effectiveness of engineered fasteners.
Confirms alloy composition and grade accuracy
Detects impurities or deviations from material specifications
Ensures consistent performance and durability
Supports regulatory, customer, and industry requirements
