2014/32/EU - Directive 2014/32/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of measuring instruments

IEC 60086-1:2021 is available as IEC 60086-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60086-1:2021 is intended to standardize primary batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, typical performance, safety and environmental aspects. This document on one side specifies requirements for primary cells and batteries. On the other side, this document also specifies procedures of how requirements for these batteries are to be standardised. As a classification tool for primary batteries, this document specifies system letters, electrodes, electrolytes, and nominal as well as maximum open circuit voltage of electrochemical systems. The object of this part of IEC 60086 is to benefit primary battery users, device designers and battery manufacturers by ensuring that batteries from different manufacturers are interchangeable according to standard form, fit and function. Furthermore, to ensure compliance with the above, this part specifies standard test methods for testing primary cells and batteries.

This document specifies the test gases, test pressures and categories of appliances relative to the use of gaseous fuels of the first, second and third families. It serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC.
The standard makes recommendations for the use of the gases and pressures to be applied for the tests. The full procedure will be given in the corresponding appliance standards.
NOTE   The test gases and the test pressures specified in this standard are in principle intended to be used with all the appliances in order to establish conformity with the corresponding standards.
However, the use of some test gases and test pressures may not be appropriate in the following cases:
-   appliances with nominal heat input greater than 300 kW;
-   appliances constructed on site;
-   appliances in which the final design is influenced by the user;
-   appliances constructed for use with high supply pressures (notably direct use of the saturated vapour pressure).
In these cases, the specific appliance standards may specify other test conditions in order to establish compliance with their requirements.

IEC 60079-10-1:2020 is concerned with the classification of areas where flammable gas or vapour hazards may arise and may then be used as a basis to support the proper design, construction, operation and maintenance of equipment for use in hazardous areas. It is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air, but it does not apply to: a) mines susceptible to firedamp; b) the processing and manufacture of explosives; c) catastrophic failures or rare malfunctions which are beyond the concept of normality dealt with in this standard; d) rooms used for medical purposes; e) domestic premises; f) where a hazard may arise due to the presence of combustible dusts or combustible flyings but the principles may be used in assessment of a hybrid mixture. Flammable mists may form or be present at the same time as flammable vapour. In such case the strict application of the details in this document may not be appropriate. Flammable mists may also form when liquids not considered to be a hazard due to the high flash point are released under pressure. In these cases the classifications and details given in this document do not apply. For the purpose of this document, an area is a three-dimensional region or space. Atmospheric conditions include variations above and below reference levels of 101,3 kPa (1 013 mbar) and 20 °C (293 K), provided that the variations have a negligible effect on the explosion properties of the flammable substances. In any site, irrespective of size, there may be numerous sources of ignition apart from those associated with equipment. Appropriate precautions will be necessary to ensure safety in this context. This standard is applicable with judgement for other ignition sources but in some applications other safeguards may also need to be considered. E.g. larger distances may apply for naked flames when considering hot work permits. This document does not take into account the consequences of ignition of an explosive atmosphere except where a zone is so small that if ignition did occur it would have negligible consequences. This third edition of IEC 60079-10-1 cancels and replaces the second edition, published in 2015, and constitutes a technical revision, see foreword for further details.

This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic
equipment to radiated electromagnetic energy. It establishes test levels and the required test
procedures.
The object of this document is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to radiated, radio-frequency
electromagnetic fields. The test method documented in this part of IEC 61000 describes a
consistent method to assess the immunity of an equipment or system against RF
electromagnetic fields from RF sources not in close proximity to the EUT. The test environment
is specified in Clause 6.
NOTE 1 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test
standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels
and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the
evaluation of the value of particular immunity tests for their products.
NOTE 2 Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39.
Particular considerations are devoted to the protection against radio-frequency emissions from
digital radiotelephones and other RF emitting devices.
NOTE 3 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the
equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for
quantitative determination of effects. The test methods defined in this basic document have the primary objective of
establishing an adequate reproducibility of testing configuration and repeatability of test results at various test
facilities.
This document is an independent test method. It is not possible to use other test methods as
substitutes for claiming compliance with this document.

This document specifies a test method for assessing the resistance of paint coatings and varnishes
(including wood stains) to separation from substrates when a right-angle lattice pattern is cut into
the coating, penetrating through to the substrate. The property determined by this empirical test
procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or
the substrate. This procedure is not, however, a means of measuring adhesion.
NOTE 1 Where a measurement of adhesion is required, see the method described in ISO 4624.
NOTE 2 Although the test is primarily intended for use in the laboratory, the test is also suitable for field
testing.
The method described can be used either as a pass/fail test or, where circumstances are appropriate,
as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to
separation of individual layers of the coating from each other can be made.
The test can be carried out on finished objects and/or on specially prepared test specimens.
Although the method is applicable to paint on hard (e.g. metal) and soft (e.g. wood and plaster)
substrates, these different substrates need a different test procedure (see Clause 8).
The method is not suitable for coatings of total thickness greater than 250 μm or for textured coatings.
NOTE 3 The method, when applied to coatings designed to give a rough patterned surface, will give results
which will show too much variation (see also ISO 16276-2).

This European Standard specifies the safety and performance requirements and tests methods for the components for supply systems. Their intended use is the supply with liquid fuel for one or more consuming units from one or more tanks.

This document specifies a test method for determining under defined conditions the resistance of a
single coating or a multi-coat system of paint, varnish or related product to penetration by scratching
with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in
the case of a multi-coat system, in which case the stylus can penetrate either to the substrate or to an
intermediate coat.
The method specified can be carried out
a) either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess
conformity with a particular specification, or
b) as an assessment test by applying increasing loads to the stylus to determine the minimum load at
which the coating is penetrated.
NOTE Neither this document nor ISO 1518-2 specifies a method using a curved stylus, which is specified in
ISO 12137. The choice between the three methods will depend on the particular practical problem.

This document specifies a method for determining, using a pointed stylus loaded with a continuously
increasing load, the scratch resistance of a single coating of a paint, varnish or related product, or the
upper layer of a multicoat system.
This test has been found to be useful in comparing the scratch resistance of different coatings. It is most
useful in providing relative ratings for a series of coated panels exhibiting significant differences in
scratch resistance.
NOTE Neither this document nor ISO 1518-1 specifies a method using a curved stylus, which is specified in
ISO 12137. The choice between the three methods will depend on the particular practical problem.

related products to conditions of condensation in accordance with the requirements of coating or
product specifications.
The method is applicable to coatings, both on porous substrates such as wood, plaster and plasterboard
and on non-porous substrates such as metal. It provides an indication of the performance likely to be
obtained under severe conditions of exposure where continuous condensation occurs on the surface.
The procedure can reveal failures of the coating (including blistering, staining, softening, wrinkling
and embrittlement) and deterioration of the substrate.
NOTE The shape and preparation of the test specimens, the duration of the test and the assessment of the
test results are not covered by this document.

This European Standard specifies ranges, construction, performances, output characteristics and testing of rotary displacement gas meters (hereinafter referred to as RD meters or simply meters) for gas volume measurement.
This European Standard applies to rotary displacement gas meters used to measure the volume of fuel gases of at least the 1st, 2nd and 3rd gas families, the composition of which is specified in EN 437:2003+A1:2009, at a maximum working pressure up to and including 20 bar over an ambient and gas temperature range of at least −10 °C to +40 °C.
This European Standard applies to meters that are installed in locations with vibration and shocks of low significance (class M1) and in
-   closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity
or, if specified by the manufacturer,
-   open locations (outdoor without any covering) with condensing humidity or with non-condensing humidity,
and in locations with electromagnetic disturbances (class E1 and E2). The standards apply to mechanical meters with mechanical index, electronic devices are not covered by this standard.
Unless otherwise specified in this standard:
-   all pressures used are gauge;
-   all influence quantities, except the one under test, are kept relatively constant at their reference value.
This European Standard applies to meters with a maximum allowable pressure PS and the volume V of less than 6 000 bar · litres or with a product of PS and DN of less than 3 000 bar.
This European Standard can be used for both pattern approval and individual meter testing. Cross-reference tables are given in:
-   Annex A for the tests that need to be undertaken for pattern approval;
-   Annex B for individual meter testing.
Some parts of this standard cover meters with mechanical index only.
The risk philosophy adopted in this standard is based on the analysis of hazards including pressure. The standard applies principles to eliminate or reduce hazards. Where these hazards cannot be eliminated appropriate protection measures are specified.
