The proposed standard defines the general principles for determining stress-strain curves for plastics in a wide strain rate field, with a focus on data entry of material cards for finite element simulations in the event of transient loads (impact/crash). The procedure is to be used to investigate the strain rate dependent uniaxial tensile deformation behaviour of test specimens and to determine…

This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…

1.1 This document — amplifies the general principles for designing experiments for the numerical estimation of the precision of measurement methods by means of a collaborative interlaboratory experiment; — provides a detailed practical description of the basic method for routine use in estimating the precision of measurement methods; — provides guidance to all personnel concerned with designing,…

This document defines the requirements and operation of the on-board vehicle equipment that enables dynamic wireless power transfer (D-WPT) for electric vehicles in motion. This document addresses the following aspects for an EV device: - general requirements in D-WPT; - transferred power and power transfer efficiency in D-WPT; - interoperability requirements in D-WPT; - safety requirements (…

NOTE 1        There is guidance or rationale for this Clause contained in Clause A.2. This document specifies the requirements for information supplied by the manufacturer for a medical device or by the manufacturer for an accessory, as defined in 3.1. This document includes the generally applicable requirements for identification and labels on a medical device or accessory, the packaging,…

This document specifies the classification for horizontal closed ice-cream freezer with access of the product from the top via transparent or solid lid(s) and specifies their requirements and test methods. The ice-cream freezers defined in this document are different from supermarket segment freezers, as they work with static air cooling, with a skin evaporator (no evaporator fan) and are used…

This document applies to the basic safety and essential performance of respiratory high-flow therapy equipment, as defined in 201.3.220, hereafter also referred to as ME equipment or ME system, in combination with its accessories: —   intended for use with patients who can breathe spontaneously; and —   intended for patients who would benefit from improved alveolar gas exchange; and who would…

ISO 16530-1:2017 is applicable to all wells that are operated by the petroleum and natural gas industry. This document is applicable to any well, or group of wells, regardless of their age, location (including onshore, subsea and offshore wells) or type (e.g. naturally flowing, artificial lift, injection wells). ISO 16530-1:2017 is intended to assist the petroleum and natural gas industry to…

The standard «criterias for quality internships» will define terms and concepts related to internships, a quality framework for internships, quality criteria, and best practices. The document is intended for companies, the public sector and other host organizations, individuals interested in or taking part in internships (either for students or non-students), higher education institutions, public…

This document establishes definitions and evaluation methods for wheel-rail contact geometry parameters influencing the vehicle running dynamic behaviour: - the rolling radius difference between the two wheels of a wheelset (Δr-function) which serves as a basis for all further calculations; - the equivalent conicity function from which are derived: • a single equivalent conicity value for a…
