1. Test results of cylindrical parts require a correction factor prior to reporting the results. Correction factors for diameters less than .125″ are not provided in the standard, therefore we interpret this as untestable and look for other test methods.
2. For other geometries, two parallel surfaces are required.
3. Spherical surfaces cannot be tested.
4. Minimum thickness is listed in tables attached.

Note: Although not covered in ASTM E-18-11, Applied Thermal Technologies Inc. has submitted concerns and recommendations to ASTM about the testing of tubular products. ASTM has informed us that our concerns will be addressed in the next revision. Possible deflection when testing the OD of tubular will result in erroneous readings since hardness is measured by the deflection of the diamond, when testing on the end is not possible to due insufficient wall thickness or geometry. The feasibility of testing tubular products will be assessed at final inspection.

Tables A5.1, A5.2, A5.3, A6.1, A6.2, and A6.3 are available for review at our location. We have reviewed the requirements with all employees to perform as follows; “If for some reason the part cannot be tested, list the hardness as “N/A”, quantity tested as “None” and reference in the “Other” section “Unable to test due to configuration”. Write a discrepancy report describing listing “Final inspection hardness test could not be performed”, write the name of the purchasing agent in the customer contact field and return to customer for disposition.”

We are requesting that you please review this information and consider the following options;

1. Include a test piece of the same material lot with your order prior to heat treatment with an outer diameter greater than 0.125”. Tests pieces must conform to the guidelines of ASTM E-18 outlined above.
2. Accept the heat treat process certification “As-Is”.
3. Perform a microhardness test per ASTM E384, which is a destructive test and will incurr an additional charge.

We, at Applied Thermal Technologies, Inc. are deeply saddened by the tragic passing of our dear friend and coworker, Lucy Saavedra. Lucy was an inspirational individual who positively influenced the lives of many who were fortunate enough to know her. Words cannot adequately express our gratitude for the opportunity to get to know Lucy over the past years.

Lucy is survived by two beautiful daughters Jacky and Melody whom are currently in the custody of her sister, Christina. Jacky is 15 years of age, and Melody is 9.

As her friends; we knew of Lucy’s desire for her daughters to one day graduate from the college of their choice. Applied Thermal has opened a college savings account for the explicit purpose of helping Jacky and Melody fulfill their mother’s dream. Contributions from our employees were matched by the company and we are seeking contributions from our friends, neighbors, and business partners. Checks to Lucy Saavedra Scholarship Fund, or cash deposits can be made at any Mutual Bank offices or at Applied Thermal’s facility.
