Surface Plate Flatness Standards

Circular hardened steel or granite toolmakers' flats up to 200 mm diameter and circular cast iron or granite high precision surface plates 250 and 400 mm diameter. Material, general design, finish, accuracy, cases, packing and marking. Composition of typical steels, cast irons...

Scope and field of application 1) This CSA Standard specifies delivery requirements which apply to the surface finish of hot-rolled plates and wide flats rolled on reversing mills, with nominal thicknesses equal to or less than 150 mm. For plates with a thickness greater...

Describes the way the surface condition of hot-rolled steel plates and wide flats is assessed and specifies limiting levels of surface discontinuities in respect of their depth, nature, and surface area.

This Part 2 in addition to Part 1 of this European Standard specifies the delivery requirements which apply to the surface condition of hot-rolled plates and surface condition of the faces of wide flats with thicknesses of 3 mm = t = 400 mm. NOTE For plates with a...

1.1 This European Standard specifies the general requirements for the surface condition of hot-rolled steel plates, wide flats and sections. It covers the requirements on the type, the permissible depth and the permissible size of the surface area affected by: -...

This part of IEC 62899 defines measurement terms and methods related to the external dimension of a rigid plate master. Measurement terms include geometrical size such as edge length, edge squareness, edge straightness and thickness, flatness of plate master substrates, and...

1.1 This practice covers definitions and procedures for measuring flatness characteristics of uncoated steel sheet and nonmetallic and metallic-coated steel sheet. The methods described are designed and intended to be used in mill situations and environments. 1.2 The sheet shall conform to...

1.1 Flatness is a significant quality characteristic of steel sheet products. Sheet flatness is affected by mill process factors plus the grade, thickness and width of the material supplied. It is the purpose of this practice to define the different flatness characteristics and...

This standard practice describes the calibration of standards for hemispherical reflectance in relation to the theoretically perfect reflecting diffuser with an assigned value of unity. The calibration of an instrument standard is made by means of a standard coated flat plate. The...

1.1 Flatness is a significant quality characteristic of steel sheet products. Sheet flatness is affected by mill process factors plus the grade, thickness and width of the material supplied. It is the purpose of this practice to define the different flatness characteristics and...
