ISO 15850-2014 pdf free.Plastics – Determination of tension- tension fatigue crack propagation – Linear elastic fracture mecl hanics (LEFM) approach. A constant-amplitude cyclic tensile load is imposed on a specimen under suitable test conditions (specimen shape and size, notching, maximum and minimum loads, load cycle frequency, etc.), causing a crack to start from the notch and propagate. The crack length a is monitored during the test and recorded as a function of the number N of load cycles completed. Numerical differentiation of the experimental function a(N) provides the fatigue crack growth rate da/dN which is reported as a function of stress intensity factor and energy release rate at the crack tip. For the case where total number of cycles to failure or time to failure is to be determined, the crack length need not be monitored. 5 Significance and use Fatigue crack propagation, particularly when expressed as the fatigue crack growth rate da/dN as a function of crack-tip stress intensity factor range K or energy release rate range G, characterizes a material’s resistance to stable crack extension under cyclic loading. Background information on the fatigue behaviour of plastics and on the fracture mechanics approach to fatigue for these materials is…

ISO 17640-2017 pdf free download.Non-destructive testing of welds – Ultrasonic testing – Techniques, testing levels, and assessment. This document specifies techniques for the manual ultrasonic testing of fusion-welded joints in metallic materials of thickness 8 mm which exhibit low ultrasonic attenuation (especially that due to scatter) at object temperatures from 0 °C to 60 °C. It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic. Where material-dependent ultrasonic values are specified in this document, they are based on steels having an ultrasonic sound velocity of (5 920 ± 50) rn/s for longitudinal waves and (3 255 ± 30) rn/s for transverse waves. This document specifies four testing levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of testing levels A, B, and C is given in Annex A. This document specifies that the requirements of testing level 0, which Is intended for special applications, be in accordance with general requirements. Testing level D can only be used when defined by specification. This includes tests of metals other than ferritic steel, tests on partial penetration welds, tests with automated equipment, and tests at object temperatures…

ISO 15622-2018 pdf download.Intellig igent transport systems – Adaptive cruise control systems – Performance requirements and test procedures. This document contains the basic control strategy, minimum functionality requirements, basic driver interface elements, minimum requirements for diagnostics and reaction to failure, and performance test procedures for Adaptive Cruise Control (ACC) systems. ACC systems are realised as either Lull Speed Range Adaptive Cruise Control (FSRA) systems or Limited Speed Range Adaptive Cruise Control (LSRA) systems. LSRA systems are further distinguished into two types, requiring manual or automatic clutch. Adaptive Cruise Control is fundamentally intended to provide longitudinal control of equipped vehicles while travelling on highways (roads where non- motorized vehicles and pedestrians are prohibited) under free-flowing and for FSRA-type systems also for congested traffic conditions. ACC can be augmented with other capabilities, such as forward obstacle warning. For FSRA-type systems the system will attempt to stop behind an already tracked vehicle within its limited deceleration capabilities and will be able to start again after the driver has input a request to the system to resume the journey from standstill. The system is not required to react to stationary or slow moving objects 2 Normative references The following documents are referred to in…
