This standard specifies the decarburized depth measurement for external thread parts Note 1) such as bolts and machine screws. Note 1) This standard shall apply mainly to the mechanical strength class 8.8 or more of the external thread parts. PURPOSE This standard aims at...
This standard provides a data representation for depth information. This information allows for simple interchange during production and post-production, and provides the essence for distribution of single-view and multi-view content. The standard specifies a 32-bit floating point...
Case hardening may be defined as a process for hardening a ferrous material in such a manner that the surface layer, known as the case, is substantially harder than the remaining material, known as the core. The process embraces carburizing, nitriding, carbonitriding, cyaniding, induction, and...
This European Standard specifies the profiles of thread for all the screw neck finishes for metallic, plastic and metallo-plastic closures. The depressed threads could be used on continuous thread finishes to reduce the thread depth at and adjacent to the mould...
This European Standard specifies the profiles of thread for all the screw deck finishes for metallic, plastic and metallo-plastic closures. The depressed threads could be used on continuous thread finishes to reduce the thread depth at and adjacent to the mould...
Work Instruction for the calibration of rail depth gauges. To be used in the absence of a manufacturers calibration instruction.
This standard specifies dimensions and technical delivery conditions for stud bolts intended for use in light metals (including aluminium). Stud bolts complying with this standard are not suitable for use in steel or cast iron. For economic reasons, it is recommended that, instead of studs with a...
Introduction This Track Work Instruction covers how to measure rail depth. See also the separate instruction: TWI 2P007 How to identify rail section & steel
This TIP will address the measurement of chordal flute depth defined as the perpendicular distance from the lowest point of a flute valley to an imaginary line tangent to two adjacent flute tips (Fig. 1). The base of the depth gage used to measure flute depth, which rests on...
This evaluation procedure describes the use of the standard depth scales for the determination of the dye concentration required to produce dyeings of visually equal depth for the purpose of colorfastness evaluations. Colorants may have different tinctorial strengths whereby equal...
This standard specifies the method of nitrided depth measurement for steel. PURPOSE This standard aims at helping test personnel perform the test in an appropriate method by describing the method of nitrided depth measurement for steel.
This standard specifies the method of decarburized depth measurement for steel. PURPOSE This standard aims at evaluating the product quality by measuring decarburized depth which affects severely mechanical properties of steels, especially fatigue strength.
1. SCOPE. This appendix covers the requirements for Thread Cutting Screws not specified in the body of WD 950. Unless otherwise specified all other requirements of WD 950 apply. 1.1 REFERENCES. IS0 1502 -General purpose metric screw threads -Gauging. 7 -. MATERIAL. Screws shall be...
This standard specifies the method of measurement for chemical compound layer thickness depth of diffused layer and surface hardness of the soft-nitriding product. PURPOSE The standard aims at helping test personnel perform the test in an appropriate method by describing the methods of...
This document defines the decarburization and specifies three methods of measuring the depth of decarburization of steel products.
This Standard covers the performance and technical requirements for gauges, submarine, depth, dial indicating bourdon tube type of the plain and clockwork types which read depth in metres of seawater. The Standard only applies to the gauges listed within. The Standard references the...
Introduction This Track Work Instruction covers how to decide on the minimum depth of ballast in situations where it is not possible to achieve full depth to Network Rail Company Specifications. See also separate instructions: TWI 3B003 How to understand blanket design TWI 3B010 How...
