This standard forms part 4 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules the methods and gives rules for measurement of pore water pressures in geotechnical engineering or more general in foundation engineering. Pore pressures are needed to obtain effective stresses and play a key role in the analysis of engineered construction in and on ground.

This European Standard specifies a method for the determination of the total pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, and feedstocks containing air, including oxygenated fuels up to 3,7%mass of oxygen and automotive ethanol (E85) fuel. A dry vapour pressure equivalent (DVPE) can be calculated from the air containing vapour pressure (ASVP) measurement.
The conditions used in the test described in this standard are a vapour-to-liquid ratio of 4:1, a sample size of 700 ml to 800 ml, and a test temperature of 37,8 °C.
This method described is suitable for testing air-saturated samples that exert an air saturated vapour pressure of between 9,0 kPa and 150,0 kPa at 37,8 °C.

This part of IEC 62828 establishes specific procedures for testing pressure process
measurement transmitters (PMT) used in measuring and control systems for industrial
processes and for machinery control systems.
A pressure PMT can feature a remote seal to bring the process variable to the sensing
element in the PMT. When the remote seal cannot be separated from the PMT, the complete
device is tested.
For general test procedures, reference is made to IEC 62828-1, which is applicable to all
types of process measurement transmitters.
NOTE In industrial and process applications, to indicate the process measurement transmitters, it is common also
to use the terms "industrial transmitters", or "process transmitters".

This standard applies to the metrological tyre pressure gauges (TPG) which operate using pressure equipment (pre-setting devices used in fixed or mobile installations) to inflate the tyres of road using vehicles (cars, trucks) and which may be capable of interacting with tyre pressure management systems (TPMS) which monitor the pressure of the tyre of the vehicle, whereby the TPG may be steered by the TPMS. This standard defines requirements for the interoperability/compatibility of TPG with TPMS/vehicle, through standardised interfaces and data exchange formats allowing advanced information and management and control systems between TPG and TPMS. The architecture must be open and scalable to support from the simplest to the most complex applications. Furthermore, the architecture must consider all current relevant communication media and be adaptable for future communication media. This standard uses communication standard(s) which must allow the secure interfacing for data exchanges between the TPG and TPMS, including the avoidance of (radio) interference. (crosstalk i.e. TPG connecting to the wrong TPMS).

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).

EN 12645 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 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 verification of tyre pressure measuring instruments is strongly recommended.

1. Scope
1.1. This document specifies the requirements for installation, calibration, performance and accuracy assessment, and test methods for Weigh-in-Motion systems.
1.2. This document applies to road vehicle Weigh-in-Motion (WIM) systems installed on or in the infrastructure.
1.3. This document applies to "HS-WIM" (High Speed 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 "LS-WIM" (Low Speed WIM) systems, i.e., systems installed in a specific weighing area, outside of the regular traffic lane(s), to which the vehicles to be weighed are diverted by a competent authority (such as police).
1.4. This document applies to 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).
1.5. The scope of this document covers all WIM needs, except trade purposes.
NOTE: For trade and legal purposes, the OIML (International Organisation for Legal Metrology) recommendation applies (OIML, 2004 & 2006). For load enforcement of road vehicles,

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.
