The testing for insulation is covered by ASTM E644 − 11. This method includes testing for resistance, calibration, immersion mistake, pressure impacts, self-response time, vibration effect, mechanical shock, self-response time, stability, thermoelectric effect, humidity, end seal integrity, improper hysteresis, and thermal shock.
Scope:
These test techniques provide uniform procedures for evaluating industrial resistance thermometers, allowing a tester to expect the same value of a test result from making the same number of tests within the same test piece.

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.
