ASTM E298-08 Standard Test Methods for Assay of Organic Peroxides
ASTM E298–08 test method covers the procedures for assaying organic peroxides to determine if they are suitable for their intended use. Organic peroxides use as chemical intermediates, catalysts, and initiators. The apparatus used is Iodine Flasks of 250-mL with stoppers.
ASTM E298–08 test method provides an assay of organic peroxides. Two test procedures are performed, depending upon the ease of reduction.
SODIUM IODIDE, ROOM TEMPERATURE TESTMETHOD
SODIUM IODIDE, 60°C TEST METHOD
Calculate the assay as follows:
A = mL of Na2S2O3 solution required for titration of the sample,
B = mL of Na2S2O3 solution required for titration of the blank,
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.
