    WE HEREBY CERTIFY THAT THIS REPORT IS CORRECT AND THAT ALL TEST RESULTS ARE IN COMPLIANCE WITH THE SPECIFICATION
    DESCRIBED HEREIN.AND THE CERTIFICATE COMPLIES TO THE REQUIREMENTS OF EN10204, Type 2.2 ALSO.

    This product satisfies the requirements of AWS D1.8/D1.8M, Annex E after exposure for two weeks at 27℃, 80% relative humidity.

    Strength values in SI units are reported to the nearest 10 MPa converted from actual data, Preheat and interpass temperature values in SI units are
    reported to the nearest 5 degrees.

    The strength and elongation properties were obtained from 12.5mm (0.5 in.), A4 tensile specimen artificially aged at 105℃ for 48 hours, as permitted by
    AWS A5.20. A naturally aged tensile specimen may take months to achieve the specified properties. See AWS A5.20, paragraph A8.3. The time required
    for the natural aging of weld deposits is dependent upon ambient conditions, weldment geometry, the metallurgical structure of the weld deposit and other
    factors.
