I. INTRODUCTION A study was performed to provide bending moment ratings as a function of internal pressure for five API clamp-hub combinations and for a heavy duty 18 3/4-10 connector, designed to withstand a one million ft·lb bending moment at working pressure. The design of the...
1.1 These test methods cover the determination of the resistance of plastics to "standardized" (see Note 1) pendulum-type hammers, mounted in "standardized" machines, in breaking standard specimens with one pendulum swing (see Note 2). The standard tests for these test methods require...

The GEO Bias tool is a MATLAB script. The GEO Bias tool is intended to be used by the manufacturer to demonstrate that their GNSS receiver is compliant with the GEO Bias requirements in DO-229E as described in section 2.1.4.1.5. Appendix T in DO-229E provides a description of this...
This document specifies technical requirements for testing procedures for evaluation of energy supplied during use phase for the design of machine tools to process wood and materials with similar physical characteristics to wood. This document, along with ISO 14955-1 and ISO 14955-2,...
5.1 The bending fatigue test described in this test method provides information on the ability of a copper alloy flat sheet and strip of spring material to resist the development of cracks or general mechanical deterioration as a result of a relatively large number of cycles (generally in...
1.1 This European Standard specifies technical safety requirements and protective measures to be adopted by persons undertaking the design as defined in 3.11 of EN 292-1:1991, manufacture and supply of pneumatic presses the intended use of which is the cold working of metal or material partly of...
5.1 Stress-relaxation test data are necessary when designing most mechanically fastened joints to ensure the permanent tightness of bolted or riveted assemblies, press or shrink-fit components, rolled-in tubes, etc. Other applications include predicting the decrease in the tightness of gaskets, in...
NOTE 1-The method of testing for the stress relaxation of plastics has been withdrawn from this standard, and the responsibility has been transferred to Practice D2991. These test methods cover the determination of the time dependence of stress (stress relaxation) in materials and structures under...
This document specifies technical requirements and measures for testing procedures for evaluation of energy required to be adopted by persons undertaking the design, manufacture and supply of metal forming and laser processing machine tools in order to achieve reproducible data about...
