This document specifies a method for the determination of the vapour pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), and feedstocks using a variable volume chamber. A dry vapour pressure equivalent (DVPE) is calculated from the vapour pressure.
The conditions used in the test described in this document are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 °C.
The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample.
This procedure calculates the partial pressure of the air dissolved in the test portion during the triple expansion process. It is suitable for samples with a DVPE between 15,7 kPa and 97,6 kPa; vapour pressures outside this range can be measured but the precision has not been determined.
This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant Council Directive 85/536/EEC [6], and for ethanol-fuel blends up to 85 % (V/V) ethanol.
NOTE   For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent the mass and volume fractions respectively.
WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and to determine the applicability of any further restrictions for this purpose.

—     monitoring of consolidation processes of soil and fill (e.g. beneath foundations and in embankments);
—     evaluating stability and serviceability of geotechnical structures;
—     checking geotechnical designs in connection with the Observational Design procedure.
NOTE    This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of piezometers, installed as part of the geotechnical investigation and testing in accordance with References [4] and [5] This document relates to measuring devices, which are installed in the ground.

This European Standard applies to the tyre pressure gauges (TPG) which operate using pressure equipment (devices used in fixed or mobile installations) to inflate the tyres of road using vehicles (M1 and M2 categories) and which may be capable of interacting with vehicles equipped with tyre pressure monitoring systems (TPMS) whereby the TPG may be steered by the TPMS/vehicle.
To set the correct tyre inflation, this European Standard defines requirements and processes for the interoperability of TPG with TPMS/vehicle, through standardized interfaces and data exchange formats allowing advanced information, management and control systems between TPG and TPMS/vehicle. The architecture is open and scalable to support the different levels of interoperability (from full interoperability to fully manual).
This European Standard does not define communication protocols (works specifically made under M/453 European mandate).
This European Standard may be applied to all TPG categories referenced in the revision of EN 12645.
The driver/operator is considered as being responsible for the validation of the parameters and tyre pressure.
This European Standard will be applicable upon development of Infrastructure solution (V2I-I2V communication solutions).

This European Standard defines metrological and technical requirements and tests of tyre pressure measuring instruments.
Tyre pressure measuring instruments (often referred to as Tyre Pressure Gauges, [TPG]) are for the inspection of pressure and/or inspection of inflation/deflation of tyres of motor vehicles.
It establishes in the context of motor vehicles tyres, the minimum characteristics of the chain of measurement of tyre pressure measuring instruments intended to increase, inspect or adjust the pressure of tyres inflated by air or nitrogen.
These devices, classified in different categories, are hereinafter referred to by generic term, "tyre pressure measuring instruments".
This chain of measurement consists of all the elements between the tyre valve and the display device (connector, hose, control device, measurement components, reservoir, preset device etc.).
They indicate the pressure difference (pe) between the air or the nitrogen in the tyre and the atmosphere.
The field of application established above can be extended to other applications where no specific standard exists.
Because of the influence of tyre pressure on road safety and energy efficiency, periodical reverification is strongly advised.

1.1   This standard specifies the requirements for installation, calibration, performance and accuracy assessment, and test methods for Weigh-in-Motion (WIM) systems, that are used to determine gross weights, axle and group-of-axle loads for road vehicles when they are weighed in motion.
1.2   This standard applies to:
1.2.1   WIM systems installed on road infrastructure (including bridges), but not to the WIM systems installed on-board of vehicles;
1.2.2   High speed WIM (HS-WIM) systems, i.e. systems installed in one or more traffic lane(s) of a road, and operated automatically under normal traffic conditions, and to low speed WIM (LS-WIM) systems, i.e. systems installed in a controlled weighing area, and operated under controlled conditions;
1.2.3   WIM systems using either scales which are able to weigh standard masses statically, or other sensors which may measure the loads indirectly;
1.2.4   on-site full WIM system performance assessment and model (type) approval, but excludes laboratory (product) tests or tests on parts of systems (e.g. sensors only).
1.6   The scope of this standard covers all WIM applications, except trade.
NOTE   For load enforcement of road vehicles, this standard or the OIML (International Organization for Legal Metrology) international recommendation R 134-1 and 134-2 (OIML, 2004 and 2006) applies, depending on the national requirements and legislation.
1.7   WIM systems used for trade are dealt with in the OIML recommendations R134-1 and R134-2 (OIML, 2006 and 2004). These OIML recommendations apply to WIM systems installed in controlled weighing areas, on a specified apron and where the vehicle speed is controlled. They mainly apply to WIM systems composed of scales, which are capable of weighing standard masses statically. The OIML recommendations are limited to the highest accuracy classes (0,2 to 10), with tolerances for 100 % of the measurements.
This standard applies to any WIM system, which may be installed either in a controlled weighing area, or on a road open to traffic. These systems may use road sensors and bridge WIM.
This standard covers type approval testing, initial and in service testing.
This standard specifies the required performance and ability of WIM systems in general, but does not aim to standardize products.
