Detta dokument bidrar till standardisering inom området naturvärdesinventering och biologisk mångfald. Det omfattar krav, principer och vägledning för inventering och värdering av ekosystem, arter och livsmiljöer samt hur inventeringsresultat ska redovisas och levereras.

Detta dokument fastställer krav och ger vägledning för den som utför kartläggning och värdering av biologisk mångfald. Det ger också vägledning för beställning av sådana kartläggningar.

Tyngdpunkten i dokumentet ligger på naturvärdesinventering (NVI). Med NVI avses en fältinventering av arter, biotoper och landskap, som innebär att resultatet redovisas som geografiska områden vilka naturvärdesbedöms i olika naturvärdesklasser.

Detta dokument omfattar även krav och vägledning för fördjupade inventeringar, vilka kan genomföras som komplement till en NVI. Fördjupade inventeringar ingick i begränsad omfattning i den förra versionen av denna standard SS199000:2014. I denna nya version har antalet fördjupade inventeringar utökats väsentligt. Dessa beskrivs mer ingående, för att kunna möta många olika behov.

Detta dokument beskriver ett koncept för naturvärdesbedömning och specificerar krav för hur en sådan ska göras. Konceptet naturvärdesbedömning presenterades för första gången i den förra utgåvan från 2014. I denna utgåva har konceptet utvecklats särskilt avseende bedömning av biotopvärde och bedömning av naturvärde på landskapsnivå.

En naturvärdesbedömning enligt detta dokument är tillämpbar i samtliga naturtyper, oavsett om de är terrestra, limniska eller marina.

Detta dokument omfattar även förstudier vilket innebär insamling, bearbetning och redovisning av information om biologisk mångfald som får göras utan fältinventering och på ett enklare sätt än vad som krävs för naturvärdesinventering och fördjupade inventeringar.

Detta dokument omfattar inte:

— standardisering av naturinventeringar som har andra syften än att värdera geografiska områden eller artförekomster efter deras betydelse för biologisk mångfald,

— standardisering av test- och mätmetoder för ekologisk kvalitet på vatten, luft, mark och marin miljö, men resultat av sådana mätningar kan utgöra stöd för naturvärdesbedömning,

— standardisering av metoder för fjärranalys, men fjärranalys kan ingår som ett hjälpmedel vid kartläggning,

— standardisering av metoder för bedömning av miljökonsekvenser, men kan användas som underlag för sådana,

— kartläggning av andra ekosystemtjänster än biologisk mångfald,

— uttolkning av vad som är tillåtligt enligt artskyddsförordningen och miljöbalken, men kan användas som underlag för sådana bedömningar.

This International Standard provides guidance for the operation and maintenance (O&M) of basic on-site domestic wastewater services (ODWS), using appropriate technologies in their entirety at any level of development. This International Standard supplements and is intended to be used in conjunction with ISO 24513 and ISO 24521.
It provides assistance to relevant authorities, training organizations, certification bodies, and other responsible entities for the development of regulations, plans, manuals as well as information and training materials addressed to operators and users of ODWS.
This International Standard is applicable to both publicly and privately operated on-site domestic wastewater (blackwater and greywater) systems, for one or more dwellings or other premises where wastewater is generated.
The scope of this International Standard includes the following:
• guidance on the O&M of on-site domestic wastewater systems from the operator’s perspective
• guidance on the O&M of on-site domestic wastewater systems from the user’s perspective
• guidance on training and information aspects
• guidance on environmental, health and safety issues
The following are outside the scope of this International Standard:
• detailed design of on-site domestic wastewater systems
• limits of acceptability for discharge of wastewater or sludge
• analytical methods
• management structure of wastewater services’ activities for O&M
• content of contracts or subcontracts
Note 1: Management of on-site domestic wastewater systems, especially in rural areas and areas under development, is sometimes provided by the owners of the premises where wastewater is generated. In
such cases, the owners of the premises carry out the management themselves. In this International Standard, the term “services” includes “self-services” provided by the owners or users of the premises.
Note 2: Especially in undeveloped areas, sanitary wastewater is collected in an undiluted form. Sources of sanitary wastewater in this International Standard are domestic, excluding stormwater runoff.

Note 3: The designation of activities as operation activities or maintenance activities can differ according to the local context. However, it is important that activities essential for the proper functioning of ODWS are carried out, no matter how these activities are designated.

This document provides guidance for:
— the sampling process of the aerosols in the air using filter media. This documentrt takes into account the specific behaviour of aerosols in ambient air (Annex B);
— the determination of the activity concentration of aerosols in the air knowing the activity deposited in the media filter;
— the operating use of continuous air monitoring devices used for real time measurement.
The activity concentration is expressed in becquerel per cubic metre (Bq∙m-3).
This document does not cover the details of measurement test techniques (gamma spectroscopy, global alpha and beta counting, liquid scintillation, alpha spectrometry) used to determine the activity deposited in the media filter, which are either based on existing standards or internal methods developed by the laboratory in charge of those measurements. Also, this document does not cover the variability of the aerosol sizes as given by the composition of the dust contained in ambient air [3],[4].
The procedures described here facilitate the sampling of aerosol bound radionuclides. It is supposed to conform to the national and international requirements for monitoring programmes safety standards of IAEA [5].
The characteristics of the sampling location (coordinates, type of vegetation, obstacles) need to be documented prior to commencing the monitoring. The guidelines of WMO include the criteria for representative measurements of temperature, wind-speed, wind direction, humidity and precipitation for all the weather stations in the world [6].

This document specifies the general requirements, based on ISO 11074 and ISO/IEC 17025, for all steps in the planning (desk study and area reconnaissance) of the sampling and the preparation of samples for testing. It includes the selection of the sampling strategy, the outline of the sampling plan, the presentation of general sampling methods and equipment, as well as the methodology of the pre-treatment of samples adapted to the measurements of the activity of radionuclides in soil including rock from bedrock and ore, construction materials and products, potery, etc. using NORM or those from technological processes involving Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) e.g. the mining and processing of mineral sands or phosphate fertilizer production and use, as well as of sludge and sediment.
For simplification, the term “soil” used in this document covers the set of elements mentioned above.
This document is addressed to the people responsible for determining the radioactivity present in soil for the purpose of radiation protection. It is applicable to soil from gardens, farmland, urban, or industrial sites, as well as soil not affected by human activities.
This document is applicable to all laboratories regardless of the number of personnel or the range of the testing performed. When a laboratory does not undertake one or more of the activities covered by this document, such as planning, sampling, or testing, the corresponding requirements do not apply.
NOTE The term “laboratory” is applicable to all identified entities (individuals, organizations,..) performing planning, sampling, test and calibration.

This document specifies requirements, test methods, marking, manufacturer’s instructions and information and packaging for guided type fall arresters including a flexible anchor line. This anchor line is usually attached to an upper anchor point. Guided type fall arresters including a flexible anchor line conforming to this document are components of one of the fall arrest systems covered by EN 363. Other types of fall arresters are specified in EN 353-1 or EN 360.

This document specifies requirements, testing, marking and manufacturer’s instructions and information for sit harnesses to be used in restraint, work positioning and rope access systems, where a low point of attachment is required. Sit harnesses are not suitable to be used for fall arrest purposes.

This document specifies methods for the determination of the liquid and plastic limits of a soil. These comprise two of the Atterberg limits for soils.
The liquid limit is the water content at which a soil changes from the liquid to the plastic state.
This document describes the determination of the liquid limit of a specimen of natural soil, or of a specimen of soil from which material larger than about 0,4 mm has been removed. This document describes two methods: the fall cone method and the Casagrande method.
NOTE The fall cone method in this document should not be confused with that of ISO 17892-6.
The plastic limit of a soil is the water content at which a soil ceases to be plastic when dried further.
The determination of the plastic limit is normally made in conjunction with the determination of the liquid limit. It is recognized that the results of the test are subject to the judgement of the operator, and that some variability in results will occur.

This document specifies two complementary methods (method A and method B) for determining the behaviour of materials for heat protective clothing subjected to heat radiation.
These tests are carried out on representative single or multi-layer textiles or other materials intended for clothing for protection against heat. They are also applicable to assemblies, which correspond to the overall build up of a heat protective clothing assembly with or without underclothing,
Method A serves for visual assessment of any changes in the material after the action of heat radiation. With method B the protective effect of the materials is determined. The materials may be tested either by both methods or only by one of them.
The tests according to these two methods serve to classify materials; however, to be able to make a statement or prediction as to the suitability of a material for protective clothing additional criteria must be taken into account.
Since the tests are carried out at room temperature the results do not necessarily correspond to the behaviour of the materials at higher ambient temperatures and therefore are only to a limited extent suitable for predicting the performance of the protective clothing made from the materials under test.

This technical document specifies requirements for immersion suits for use by helicopter crew members and passengers in the event of a ditching or water impact, to ensure minimum levels of performance. It applies to immersion suits for use by adults only.
