This document defines general requirements, performance requirements and conformity test procedures for automatic sampling devices (samplers) for water and waste water that:
— sample water and waste water from non-pressurized (i.e. open to atmosphere) channels or vessels;
— sample over extended periods to collect discrete or composite samples based on time, event or flow proportional sampling.
It does not include sampling systems built into online and in-line analysers.
The general requirements include functional facilities that samplers need to meet users’ applications and information that needs to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of samplers. All of the test procedures are expected to be carried out under laboratory conditions. It is recognized that for some samplers certain test procedures are not applicable.
Statistical procedures are defined for evaluation of the test data. Some example calculations are provided.
Specific sample integrity requirements are defined for samplers to be used for the collection of samples of final effluent or influent for the purpose of monitoring the performance of waste water treatment works, as required under the EU’s Urban Waste Water Treatment Directive (UWWTD). Samplers to be used for other industrial applications do not need to be assessed against these specific sample integrity requirements.
This document does not cover the installation and on-going use of samplers.

The scope of this European Standard is restricted to the measurement of vertical wheel forces and calculation of derived quantities on vehicles in service. Measurements of a train in motion are used to estimate the static forces.
Derived quantities can be:
- axle loads;
- side to side load differences of a wheel set, bogie, vehicle;
- overall mass of vehicle or train set;
- mean axle load of a vehicle or train set.
This standard is not concerned with the evaluation of:
- dynamic wheel force or derived quantities;
- wheel condition (i.e. shape, profile, flats);
- lateral wheel force;
- combination of lateral and vertical wheel forces. 
The standard defines accuracy classes for measurements to be made at any speed greater than 5 km/h within the calibrated range, which may be up to line speed.
The aim of this standard is to obtain measurement results that give representative values for the distribution of vertical wheel forces of a running vehicle, which under ideal conditions will be similar to those that can be obtained from a standing vehicle.
This standard does not impose any restrictions on the types of vehicles that can be monitored, or on which networks or lines the measuring system can be installed.
The standard lays down minimum technical requirements and the metrological characteristics of a system for measuring and evaluating a range of vehicle loading parameters. Also defined are accuracy classes for the parameters measured and the procedure for verifying the calibration.
The measuring system proposed in this standard should not be considered as safety critical. If the measuring system is connected to a train traffic command and control system then requirements that are not part of this standard may apply.
Measuring systems complying with this standard have the potential to enhance safety in the railway sector. However, the current operating and maintenance procedures rather than this standard are mandatory for ensuring safety levels in European rail networks.

This document covers the general description of benchmarking test piece geometries along with quantitative and qualitative measurements to be taken on the benchmarking test piece(s) to assess the performance of additive manufacturing (AM) systems.

This performance assessment can serve the following two purposes:

—    AM system capability evaluation;

—    AM system calibration.

The benchmarking test piece(s) is (are) primarily used to quantitatively assess the geometric performance of an AM system. This document describes a suite of test geometries, each designed to investigate one or more specific performance metrics and several example configurations of these geometries into test piece(s). It prescribes quantities and qualities of the test geometries to be measured but does not dictate specific measurement methods. Various user applications can require various grades of performance. This document discusses examples of feature configurations, as well as measurement uncertainty requirements, to demonstrate low- and high-grade examination and performance. This document does not discuss a specific procedure or machine settings for manufacturing a test piece.

This part of ISO 5167 specifies the geometry and method of use (installation and operating conditions) of cone meters when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.

As the uncertainty of an uncalibrated cone meter may be too large for a particular application, it may be deemed essential to calibrate the flow meter in accordance with section 7 of this document.  Calibrated meters shall only be used over the calibrated Reynolds number range.

This part of ISO 5167 also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167-1.

This part of ISO 5167 is applicable only to cone meters in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase.  Uncalibrated cone meters can only be used within specified limits of pipe size, roughness,  and Reynolds number. This part of ISO 5167 is not applicable to the measurement of pulsating flow.  It does not cover the use of uncalibrated cone meters in pipes sized less than 50 mm or more than 500 mm, or where the pipe Reynolds numbers are below 8 x 104.

A cone meter is a primary device which consists of a cone-shaped restriction held concentrically in the centre of the pipe with the cone apex upstream.  The design of cone meter defined in this standard has one or more upstream pressure tappings in the wall, and a downstream pressure tapping positioned in the back face of the cone with the connection to a differential pressure transmitter being a hole through the cone to the support bar, and then up through the support bar. 

Alternative designs of cone meters are available; however, at the time of writing there is insufficient data to fully characterise these devices, and therefore these meters shall be calibrated in accordance with Section 7

This part of ISO 5167 specifies the geometry and method of use (installation and operating conditions) of wedge meters when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.

As the uncertainty of an uncalibrated wedge meter can be too large for a particular application, it might be deemed essential to calibrate the flow meter in accordance with Clause 7 of this document. This part of ISO 5167 includes requirements for calibration which, if applied, are for use over the calibrated Reynolds number range. Clause 7 might also be useful guidance for calibration of meters of similar design but which fall outside the scope of this document.

This part of ISO 5167 also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167‑1.

This part of ISO 5167 is applicable only to wedge meters in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. Uncalibrated wedge meters can only be used within specified limits of pipe size, roughness, beta (or wedge ratio) and Reynolds number.  This part of ISO 5167 is not applicable to the measurement of pulsating flow.  It does not cover the use of uncalibrated wedge meters in pipes sized less than 50 mm or more than 600 mm, or where the pipe Reynolds numbers are below 1 × 104.

A wedge meter has a primary element which consists of a wedge-shaped restriction of a specific geometry.  Alternative designs of wedge meters are available; however, at the time of writing there is insufficient data to fully characterize these devices, and therefore these meters shall be calibrated in accordance with Clause 7.

This document specifies a method of comparing traffic noise on different road surfaces for various compositions of road traffic for the purpose of evaluating different road surface types. Sound levels representing either light or heavy vehicles at selected speeds are assigned to a certain road surface. The method is applicable to traffic travelling at constant speed, i.e. free-flowing conditions at posted speeds of 50 km/h and upwards. For conditions where traffic is not free flowing, such as at junctions and where the traffic is congested, the method is not applicable.

A standard method for comparing the noise characteristics of road surfaces gives road and environment authorities a tool for establishing common practices or limits regarding the use of road surfaces meeting certain noise criteria. However, it is not within the scope of ISO 11819-series to suggest such criteria.

The Statistical Pass-By (SPB) method is suitable for use for the following main purposes:

—    to classify road surfaces according to their influence on traffic noise (surface classification).;

—    to assist in verifying conformity of production of road surfaces;

—    to evaluate acoustic performance of road surfaces throughout operation relative to new condition;

—    to evaluate the influence of different road surfaces on traffic noise at sites irrespective of condition and service time;

—    to evaluate acoustic performance of a road surface relative to a reference surface.

Due to practical restrictions, the method cannot be applied at all possible locations. However, the backing board method can allow some locations to be tested that were not previously acceptable.

Clause 5 gives a general description of the SPB method.

This part of ISO 14644 describes the classification of the particle contamination levels on solid surfaces in cleanrooms and associated controlled environment applications. Recommendations on testing and measuring methods as well as information about surface characteristics are given in informative annexes.

 

This part of ISO 14644 applies to all solid surfaces in cleanrooms and associated controlled environments such as walls, ceilings, floors, working environment, tools, equipment and devices. The surface particle cleanliness (SPC) classification is limited to particles between 0,05 µm and 500 µm.

 

The following issues are not considered in this standard:

 

requirements on the cleanliness and suitability of surfaces for specific processes;

 

procedures for the cleaning of surfaces;

 

material characteristics;

 

other characteristics of particles such as electrostatic charge, ionic charges, biological state and others.

 

This part of ISO 14644 covers the classification system of surface particle contamination but does not reference the interactive bonding forces or generation processes that are usually time-dependent (such as deposition, sedimentation, aging) and process-dependent (such as transportation or handling). Measurement methods of the classification should be adapted for surface characteristics (such as porosity, roughness, electrostatic charge, surface energy.).

 

The surface cleanliness depends upon material and design characteristics, stress loads (complexity of loads acting on a surface) and prevailing environmental conditions, along with other factors.

 

Due to the complexity of statistical evaluations and available bibliography, the selection and use of statistical methods for classification and testing are not described in this part of ISO 14644.
