Non-destructive testing — Ultrasonic guided-wave testing using the phased-array technique
This document specifies a concept of application of phased-array guided-wave testing for various types of inaccessible structures, including buried pipelines.
Materials considered are carbon steel and stainless steel. This document does not include principles and criteria for underground facilities and the phased-array ultrasonic guided-wave testing scheme.
Furthermore, this document consists of…
This document specifies requirements for wire rod for bridge cable wire, which is widely used in parallel wire cables or semi-parallel wire cables for suspension bridges, stay bridges or other structures involving the use of parallel wires.
ISO 16120-4 provides additional wire rod materials and their technical and qualitative requirements for their possible application as bridge cable wire.
ISO general purpose screw threads — Basic and design profiles — Part 1: Metric screw threads
This document specifies the basic and design profiles for ISO general purpose metric screw threads (M).
This document is applicable to the metric fastening screw threads.
ISO general purpose screw threads — Basic and design profiles — Part 2: Inch screw threads
This document specifies the basic and design profiles for ISO inch screw threads (UN and UNR).
UN applies to both internal and external threads. UNR only applies to external threads. A flat or rounded root contour, due to the threading process, is specified for UN threads, while only a defined rounded root contour is specified for UNR external threads.
This document is applicable to the inch…
