ASTM A947:16 pdf download.Standard Specification for Textured Stainless Steel Sheet [Metric].
6.2 The customer shall either provide a control-sample (300 by 400 mm) or designate a control-sample from a chosen textured material to ensure accurate repetition in appearance of like products. See Section 13.
7. Chemical Composition
7.1 The heat chemical composition shall be reported to the purchaser, or his representative, and shall conform to the requirements specified in the applicable ASTM standard of the steel type selected for texturing.
7.2 Methods and practices relating to chemical analysis required by this specification shall be in accordance with Test Methods, Practices, and Terminology A75 1.
8. Other Requirements
8.1 If requested by the purchaser, physical (electrical and optical) and mechanical (tensile, yield, and elongation) property requirements shall be reported to the purchaser based on a lot size as specified in 8.2.
8.2 A lot shall consist of all sheets of the same thickness made from the same coil. In case the material cannot be identified by coil, a lot shall consist of no more than 5000 kg (approximately 5 tons) of sheets of the same thickness.
8.3 Electrical Requirements:
8.3.1 The specific resistivity of the material measured at
20°C to be reported in ohms•mm2/m (i2•cm).
8.3.2 The surface resistivity of the material measured at
20°C to be reported in milliohms. Refer to Test Methods D257.
8.4 Optical Requirements—The textured surface of the material selected under this specification shall meet the inspection requirements (see 13.2) based on a visual sample comparison or a 6: 1 art master pattern comparison, or both.
8.5 Mechanical Requirements—The mechanical properties, tensile strength, yield strength, and elongation of the material selected for texturing shall be reported in values specified in 12.5 of this specification.
9. Dimensions, Mass, and Permissible Variations
9.1 Unless noted in the purchase order, the stated tolerance conditions in Tables 1-5 are deemed to he acceptable.
9.2 Table I lists the tolerance for sheet thickness relevant to the preferred thickness sizes of textured sheets in this specification.
9.3 Table 2 lists the tolerance for sheet widths relevant to the preferred width sizes of textured sheets in this specification.
9.4 Table 3 lists the tolerance thr sheet lengths relevant to the preferred length sizes in this specification.
9.5 Table 4 lists the permissible tolerance for sheet flatness relevant to the preferred flatness tolerances in this specification as a ratio of: deviation “D” to length “U and width “W” of textured sheet. (See 10.5.)
9.6 Table 5 lists the maximum permissible difference between the diagonal dimensions “AA” and “RB” of the textured sheet. (See 10.6 and Fig. I.)
