Bituminous mixtures - Test methods - Part 18: Binder drainage

This document describes two test methods: - basket method (see Clause 4); - beaker method (see Clause 5). The basket method describes a method for determining binder drainage of bituminous mixtures. This method directly measures binder drainage, but when carried out on bituminous mixtures with fibres or mixtures whose mortar content is higher than in porous asphalt some clogging of the holes in the drainage baskets can occur, limiting the drainage of the binder. The basket method can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified. The beaker method describes a method for determining binder drainage of bituminous mixtures. It is applicable to asphalt materials that are not porous asphalt or for porous asphalt incorporating fibres. It can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified.

Railway applications - Environmental conditions for equipment

This document intends to define environmental conditions within Europe. This document does not specify the test requirements for equipment. The scope of this document covers the definitions and ranges of the following parameters: altitude, temperature, pressure, humidity, air movement, rain, snow, hail, ice, lightning, electromagnetic compatibility, solar radiation, pollution, vibrations and shocks, environmental conditions in tunnels. The scope of this document is to define environmental conditions in railway environment in order to cover the design and the use/service of the following: — equipment for rolling stock and on-board equipment (mechanical, electromechanical, electrical, electronic); — fixed electrical installations for traction power supply and equipment essential to operate a railway; — equipment and any portable equipment for signalling and telecommunications systems (including test, measure, monitoring equipment, etc.). The defined environmental conditions, including the values herein specified, are considered as normal and do not concern extreme conditions or natural disasters (e.g earthquake, nuclear radiation). This document does not apply to cranes, mining vehicles, cable cars, escalators, lifts, fire protection, lighting in tunnels and on platforms, ticket machines, ventilation systems, installations in underground mines, suspended cable cars and funicular railways. The effects of vandalism on the equipment are not considered in this document.

Cryogenic vessels - Pressure-relief accessories for cryogenic service - Part 3: Sizing and capacity determination (ISO/DIS 21013-3:2025)

ISO 21013-3:2016 provides separate calculation methods for determining the required mass flow to be relieved for each of the following specified conditions: - vacuum-insulated vessels with insulation system (outer jacket + insulating material) intact under normal vacuum, outer jacket at ambient temperature, inner vessel at temperature of the contents at the specified relieving pressure; - vacuum-insulated vessels with insulation system (outer jacket + insulating material) intact under normal vacuum, outer jacket at ambient temperature, inner vessel at temperature of the contents at the specified relieving pressure, pressure regulator of the pressure build-up system functioning at full potential; - vacuum or non-vacuum-insulated vessels with insulation system remaining in place, but with loss of vacuum in the case of vacuum-insulated vessels, outer jacket at ambient temperature, inner vessel at temperature of the contents at the specified relieving pressure or vacuum or non-vacuum-insulated vessels with insulation system remaining fully or partially in place, but with loss of vacuum in the case of vacuum-insulated vessels, fire engulfment, inner vessel at temperature of the contents at the specified relieving pressure; - vacuum-insulated vessels containing fluids with saturation temperature below 75 K at 1 bar with insulation system remaining in place, but with loss of vacuum with air or nitrogen in the vacuum space; - vacuum insulated vessels containing fluids with saturation temperature below 75 K at 1 bar with insulation system remaining in place, but with loss of vacuum with air or nitrogen in the vacuum space with fire engulfment; - vessels with insulation system totally lost and fire engulfment. Good engineering practice based on well-established theoretical physical science needs to be adopted to determine the required mass flow where an appropriate calculation method is not provided for an applicable condition. Recommendations for pressure relief devices for cryostats are given in Annex A.
