CEN - European Committee for Standardization

ISO 23913:2006 specifies flow injection analysis (FIA) and continuous flow analysis (CFA) methods for the determination of chromium(VI) in various types of water. The method applies to the following mass concentration ranges: for FIA (20 to 200 micrograms per litre and 200 to 2 000 micrograms per litre for surface water, leachates and waste water) and for CFA (2 to 20 micrograms per litre and 20 to 200 micrograms per litre for drinking water, ground water, surface water, leachates and waste water). The range of application may be changed by varying the operating conditions. Seawater may be analysed by these methods with changes in sensitivity and after adaptation of the reagent and calibration solutions to the salinity of the samples.

ISO 18412:2005 specifies a method for the determination of chromium(VI) in drinking water in mass concentrations between 2 micrograms per litre and 50 micrograms per litre. For the determination of higher concentrations, the sample is diluted prior to analysis. The method may also be applied to weakly polluted ground and surface water, provided the matrix does not contain interfering reducing agents. This method was not used for estuarine water and seawater, so the user is responsible for the validation of the method for these matrices.

This document specifies three procedures, A, B and C, using the Pensky-Martens closed cup tester, for determining the flash point of combustible liquids, liquids with suspended solids, liquids that tend to form a surface film under the test conditions, biodiesel and other liquids in the temperature range of 40 °C to 370 °C.
NOTE 1        Although, technically, kerosene with a flash point above 40 °C can be tested using this document, it is standard practice to test kerosene according to ISO 13736.[5] Similarly, lubricating oils are normally tested according to ISO 2592.[2]
Procedure A is applicable to distillate fuels (diesel, biodiesel blends, heating oil and turbine fuels), new and in-use lubricating oils, paints and varnishes, and other homogeneous liquids not included in the scope of procedures B or C.
Procedure B is applicable to residual fuel oils, cutback residuals, used lubricating oils, mixtures of liquids with solids, and liquids that tend to form a surface film under test conditions or are of such kinematic viscosity that they are not uniformly heated under the stirring and heating conditions of procedure A.
Procedure C is applicable to fatty acid methyl esters (FAME) as specified in specifications such as EN 14214[11] or ASTM D6751.[13]
This document is not applicable to water-borne paints and varnishes.
NOTE 2        Water-borne paints and varnishes can be tested using ISO 3679.[3] Liquids containing traces of highly volatile materials can be tested using ISO 1523[1] or ISO 3679.

This document specifies the competencies required of assistance dogs’ professionals. The purpose of this document is to improve and ensure the quality of professionals working in a role within an assistance dog organization. Each speciality of assistance dog requires a specific set of role competencies and there are some common core competencies.
Core competencies in:
-   breeding;
-   puppy raising;
-   dog care;
-   assessors;
-   orientation and mobility;
-   trainers;
-   instructors.
Specific competencies to train:
-   guide dogs;
-   hearing dogs;
-   medical alert dogs;
-   mobility assistance dogs;
-   autism and development disorder dogs;
-   team training instructor.
It is accepted that assistance dog organisations vary greatly in structure and not every organization will have all the roles identified. Where one person performs more than one role, it is expected that they will have the competencies of all the roles they perform e.g. a dog trainer may also have the competencies of a dog care specialist. And there will be some organisations where some of these roles are not required, e.g. those with no breeding programme will not require the associated role competencies.

This International Standard describes the general principles of acoustic emission testing (AT) of
materials, components, and structures made of fibre-reinforced polymers (FRP) with the aim of
— materials characterization,
— proof testing and manufacturing quality control,
— retesting and in-service testing, and
— health monitoring.
This International Standard has been designed to describe specific methodology to assess the integrity
of fibre-reinforced polymers (FRP), components, or structures or to identify critical zones of high
damage accumulation or damage growth under load (e.g. suitable instrumentation, typical sensor
arrangements, and location procedures).
It also describes available, generally applicable evaluation criteria for AT of FRP and outlines procedures
for establishing such evaluation criteria in case they are lacking.
This International Standard also presents formats for the presentation of acoustic emission test data
that allows the application of qualitative evaluation criteria, both online during testing and by post-test
analysis, and that simplify comparison of acoustic emission test results obtained from different test

NOTE The structural significance of the acoustic emission cannot in all cases definitely be assessed based on
AT evaluation criteria only but can require further testing and assessment (e.g. with other non-destructive test
methods or fracture mechanics calculations).
