Traffic control equipment - Signal heads
Scope:
This document applies to signal heads with one or more signal lights of the colours red, yellow and/or green signal lights for road traffic with 200 mm and 300 mm roundels and to optical units to be integrated in signal heads to produce the individual signal lights. It defines the product characteristics for the visual, structural, environmental performances and testing of signal heads and optical units for pedestrian and road traffic use, and the rules for the evaluation of the conformity of these products.
This document can be partly or fully applied on a voluntary basis to other signal heads outside of the scope specified above like for instance white optical units or small signal heads with a diameter smaller than 200 mm.

Property valuation - Part 4: Professional ethics of an appraiser and valuation reporting
Scope:
The standard series EVS 875 applies to property valuation. These standards are used for valuation activities and for using valuations, especially activities related to mortages and financial reporting. The standards are intended to be used by real estate specialists, construction specialists, environment specialists, financial reporting specialists (accountants, auditors), credit institutions, higher education institutions. These standards create a basis for a unified approach to property valuation, satisfying the needs of the private and public sector.
This part of the EVS 875 defines the code of conduct and requirements of reporting. This part of the Estonian standard describes professional requirements of the valuer, the valuer's professional ethics and requirements related to the conduction of the valuation procedure and reporting, including requirements for different forms of valuation reports. This is a revision of the standard EVS 875-4:2015 "Professional Ethics of a Valuer and Valuation Reporting".

Characterization of pavement texture by use of surface profiles — Part 4: One third octave band spectral analysis of surface profiles
Scope:
This document describes the methods that are available to perform a spectral analysis of a pavement surface profile. It specifies a method for performing spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement texture amplitude as a function of the distance along a straight or curved trajectory over the pavement. It also details an alternative (non-preferred) method to obtain these spectra:
a) constant-percentage bandwidth obtained by digital filtering (normative method);
b) constant narrow bandwidth frequency analysis by means of discrete Fourier transform (DFT), followed by a transformation of the narrow-band spectrum to an octave- or one-third-octave-band spectrum (informative).
The result of the frequency analysis will be a spatial frequency (or texture wavelength) spectrum in constant-percentage bandwidth bands of octave or one-third-octave bandwidth.
The objective of this document is to standardize the spectral characterization of pavement surface profiles. This objective is pursued by providing a detailed description of the analysis methods and related requirements for those who are involved in pavement characterization but are not familiar with general principles of frequency analysis of random signals. These methods and requirements are generally applicable to all types of random signals; however, they are elaborated in this document for their use in pavement surface profile analysis.
NOTE The spectral analysis as specified in this document cannot express all characteristics of the surface profile under study. In particular, the effects of asymmetry of the profile, e.g. the difference of certain functional qualities for “positive” and “negative” profiles cannot be expressed by the power spectral density, as it disregards any asymmetry of the signal (see Annex B).

Characterization of pavement texture by use of surface profiles -- Part 4: Spectral analysis of surface profiles
Scope:
ISO/TS 13473-4:2008 describes the methods that are available to perform a spectral analysis of pavement surface profile signals. It specifies three possible methods for spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement roughness amplitude as a function of the distance along a straight or curved trajectory over the pavement. The result of the frequency analysis will be a spatial frequency (or texture wavelength) spectrum in constant-percentage bandwidth bands of octave or one-third-octave bandwidth.
ISO/TS 13473-4:2008 offers three alternative methods to obtain these spectra: 1) analogue constant-percentage bandwidth filtering; 2) digital constant-percentage bandwidth filtering; 3) constant narrow bandwidth frequency analysis by means of Discrete Fourier Transform, followed by a transformation of the narrow-band spectrum to an octave- or one-third-octave-band spectrum.

Characterization of pavement texture by use of surface profiles - Part 5: Determination of megatexture (ISO/DIS 13473-5:2024)
Scope:
ISO 13473-5:2009 specifies procedures for determining the average depth or level of pavement surface megatexture by measuring the profile curve of a surface and calculating megatexture descriptors from this profile. The technique is designed to give meaningful and accurate measurement and description of pavement megatexture characteristics for various purposes.
Since there is an overlap between megatexture and the surrounding ranges, the megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. ISO 13473-5:2009 specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 8608 and EN 13036-5.
