ASTM D3677 Introduction
The ASTM D3677 test method identifies rubber and ensures reagent purity. Analyzing the composition of rubbers in cured, compounded products is valuable for research, development, and quality control purposes. ASTM D3677 utilizes an infrared methodology to facilitate composition analysis.
ASTM D3677 Test Method
Pyrolysis
The ASTM D3677 test method involves pyrolyzing extracted and dried rubber in a stream of nitrogen within a test tube placed in a small electric, thermo-regulated furnace operating within a specific temperature range.
Chlorine Tests and Infrared Spectrum Measurement
The chlorine test is conducted, and the infrared spectrum is measured while transferring the pyrolyzate to a salt plate. Rubber identification is achieved by comparing it to standard reference spectra and referring to a table of diagnostic absorptions.
D3677 Equipment and Sample Preparation
Specimen Details
ASTM D3677 involves rubber identification through infrared examination of pyrolysis products (pyrolyzed) and films. ASTM D3677 applies to rubbers in their raw state and, when compounded, in both the cured and uncured states.
Specimen Size
The specimen size should meet the specified requirements. For the ASTM D3677 test, a sample measuring 2 mm wide is prepared and wrapped in approximately 0.5 g of filter paper or nylon cloth.
D3677 Test Results and Interpretation
The ASTM D3677 test method is essential for checking materials’ quality assurance and durability. It involves a detailed analysis, and rubber is identified by applying appropriate procedures.
