This document describes the procedure for determining objectively the chalking resulting from natural or artificial weathering of an organic coating on a metallic substrate.

The advantage of this procedure for measuring chalking of an organic coating is that the result can be read off immediately on an instrument. Subjective judgement by visual comparison of test specimens with reference specimens is not necessary.

Reproducible results can only be obtained by careful execution of the test. Special attention is paid to the adhesive tape and its application to the test surface.

The test method is not applicable to embossed coatings. In the case of textured coatings, the degree of texture will influence readings. Also, dirt collection can influence readings on outdoor weathered specimens.

NOTE          Different methods for assessing chalking are in use. The results of these different methods are not comparable.

This part of IEC 62471 specifies an assessment of the photobiological safety of electrical light sources and luminaires in normal use. The assessment is applied for electrical light sources and luminaires that emit radiation predominantly in the visible spectral range (380 nm to 780 nm) and are used to illuminate spaces or objects or used for signalling.

Electrical light sources and luminaires designed for emitting radiation in the visible range can also emit radiation in the ultraviolet (UV) and infrared (IR) regions depending on the technology applied. The photobiological safety assessment in this document, therefore, includes the blue light-, thermal-, UV-, UV-A-, IR- and skin thermal- hazards (includes optical radiation over the wavelength range 200 nm to 3 000 nm).

Electrical light sources and luminaires that are designed to predominantly emit radiation outside the visible spectral range (380 nm to 780 nm) (e.g. UV sterilizers or industrial heaters) are not within the scope of this document.

Electrical light sources for illumination are considered to emit continuous light (pulse width modulation (PWM) are included), therefore emission levels of continuous light (continuous wave (CW)) are applied.

When there is no limitation on the presence of people, this document can be applied to electrical light sources and luminaires which emit visible light, but the main purpose is not illumination or signalling (e.g. horticulture).

This document also applies to laser products when the conditions of IEC 60825-1:2014, 4.4 are met and they are used for illumination or signalling.

Note:       See IEC 60825-1:2014 for other requirements of laser products.

This document is intended to be referenced by TC 34 product standards for the assessment of applicable photobiological safety aspects. Additional details for the photobiological safety assessment and data presentation are specified in the product standards.

This part of IEC 62351 specifies how to provide confidentiality, integrity protection, and message level authentication for protocols that make use of TCP/IP as a message transport layer and utilize Transport Layer Security when cyber-security is required. This may relate to SCADA and telecontrol protocols, but also to additional protocols if they meet the requirements in this standard.

IEC 62351-3 specifies how to secure TCP/IP-based protocols through constraints on the specification of the messages, procedures, and algorithms of Transport Layer Security (TLS) (TLSv1.2 defined in RFC 5246, TLSv1.3 defined in RFC 8446). In the specific sections, there will be subclauses to note the differences and commonalities in the application depending on the target TLS version. The use and specification of intervening external security devices (e.g., “bump-in-the-wire”) are considered out-of-scope.

In contrast to former versions of this standard, this edition is self-contained in terms of completely defining a profile of TLS. Hence, it can be applied directly, without the need to specify further TLS parameters. Therefore, this part can be directly utilized from a referencing standard and may be combined with further security measures on other layers. Providing the profiling of TLS without the need for further specifying TLS parameters allows to declare conformity to the described functionality without the need to involve further IEC 62351 documents.

This part is intended to be referenced as a normative part of other IEC standards that have the need for providing security for their TCP/IP-based protocol exchanges under similar boundary conditions. However, it is up to the individual protocol security initiatives to decide if this standard is to be referenced.

The document also defines security events for specific conditions, which support the error handling, security audit trails, intrusion detection and conformance testing. The actions of the organisation in response to events to an error condition described in this document are beyond the scope of this document and are expected to be defined by the organizations security policy.

This part of IEC 62351 reflects the security requirements of the IEC power systems management protocols. Should other standards bring forward new requirements, this standard may need to be revised.

This part of IEC 61108 specifies the minimum performance requirements, methods of testing and required test results for IRNSS shipborne receiver equipment, based on IMO resolution MSC.449(99) which uses the signals from the Indian Regional Satellite System (IRNSS) in order to determine position.

It takes account of the general requirements given in IMO resolution A.694(17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. It also takes into account, as appropriate, requirements for the presentation of navigation-related information on shipborne navigational displays given in IMO resolution MSC.191(79) and is associated with IEC 62288.

This receiver standard applies to navigation in ocean waters for the standard positioning service and harbour entrances, harbour approaches and coastal waters, as defined in IMO resolution A.1046(27) within IRNSS/NavIC coverage area.

All text of this standard, whose meaning is identical to that in IMO resolution MSC 449(99), is printed in italics and the resolution and paragraph number indicated between brackets i.e. (M.449(99)/A1.2).

The requirements in Clause 4 are cross-referenced to the tests in Clause 5 and vice versa.

This document describes a standard method for determining the PM10 or PM2,5 mass concentrations of suspended particulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance.

Measurements are performed with samplers with inlet designs as specified in Annex A, operating at a nominal flow rate of 2,3 m3/h, over a nominal sampling period of 24 h. Measurement results are expressed in µg/m3, where the volume of air is the volume at ambient conditions near the inlet at the time of sampling.

The range of application of this document is for 24 h measurements from approximately 1 µg/m3 (i.e. the limit of detection of the standard measurement method expressed as its uncertainty) up to 150 µg/m3 for PM10 and 120 µg/m3 for PM2,5.

NOTE 1       Although the European Standard is not validated for higher concentrations, its range of application could well be extended to ambient air concentrations up to circa 200 µg/m3 when using suitable filter materials (see 5.1.5.2).

This document describes procedures and gives requirements for the testing and use of so-called sequential samplers, equipped with a filter changer, suitable for extended stand-alone operation. Sequential samplers are commonly used throughout the European Union for the measurement of concentrations in ambient air of PM10 or PM2,5. However, this document does not exclude the use of single-filter samplers.

NOTE 2       Older versions of samplers, which conform to previous versions of EN 12341, can still be used to evaluate equivalence of candidate methods, using the procedures described in EN 16450 and in [11]. As newer versions of samplers tested under this document become available, discontinue the use of older reference samplers in EN 16450 and in [11]. Type testing reports of equivalent methods are still valid if they were commissioned prior to the availability of reference methods tested under this document.

This document also provides guidance for the selection and testing of filters with the aim of reducing the measurement uncertainty of the results obtained when applying this document.
