This document specifies a fire test method for assessing the fire performance of water-filled plastic pipes and fibre reinforced plastic (FRP) pipes. This document provides a fire test method to be conducted in light of the application of IMO Assembly resolution A.753(18)[1]the Guidelines for the application of plastic pipes on Ships, as amended.

 

Tämä standardi on laadittu eurooppalaista yhdenmukaistettua tuotestandardia SFS-EN 1168 + A3 täydentãväksi kansalliseksi soveltamisstandardiksi, jossa esitetään suositus, mitkä ominaisuudet on ilmoitettava ko. tuotestandardin mukaan CE-merkityille normaalipainoisesta betonista valmistetuille esijännitetyille ontelolaatoille eri käyttökohteissa, sekä niille ominaisuuksille asetetut vähimmäisvaatimustasot tai luokat. Lisäksi esitetããn joukko suosituksia tuotestandardin SFS-EN 1168 + A3 muusta soveltamisesta. Tämä standardi perustuu eurokoodimitoitukseen. Huom. Standardi SFS-EN 1168 + A3 koskee myös betoniteräksillä raudoitettuja ontelolaattoja. Niitä ei käsitellä tässä soveltamisstandardissa.

This document specifies a general information model for provenance of biological material. The requirements defined here are applicable to organizations, authorities and industries carrying out or being involved in activities related to biological material, generating, collecting, analyzing or storing data on biological material, manufacturing devices or software for the aforementioned tasks, or providing facilities for these tasks. This standard defines a provenance information model suitable for describing source material, from which the sample originates, and all steps in its life cycle from acquisition, transport, and processing to storage and disposal. The biological material can be from multicellular organisms (e.g. human, animal, fungus and plant), microorganisms, or environmental samples.

 

This document specifies a method for determining the film thickness of a coating on concrete substrate by cross-section method. Coatings of various types shall meet the respective technical requirements. Furthermore, physical properties depend strongly on the film thickness. Hence, the knowledge of the film thickness in a coating system is important for the product development as well as for the application and evaluation of claims. Determining the film thickness of systems filled with quartz sand can be particularly difficult. This document describes the method for a measurement of film thickness in cured flooring system build-ups.

 

This document specifies a method to measure gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides using Liquid Scintillation Counting (LSC). The method is applicable to all types of waters with a dry residue of less than 5 g·l-1and when no correction for colour quenching is necessary. The method is applicable to test samples non-saline waters following proper sampling, handling and preparation. Gross alpha and beta measurements do not provide the exact radioactive content of a sample but estimate activity based on standard calibration sources. These measurements, known as the alpha and beta index, serve as screening tools for an initial assessment of total radioactivity. The method covers non-volatile radionuclides below 80 °C, since some gaseous or volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation. The method is applicable to test samples of drinking water, rain water, surface and ground water as well as cooling water, industrial water, domestic and industrial waste water after proper sampling and test sample preparation (filtration when necessary and taking into account the amount of dissolved material in the water). The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency and the counting time. The detection limit of the method described in this document, using currently available liquid scintillation apparatus, is approximately 20 mBq·kg-1(a) and 100 mBq·kg-1(ß), which is lower than the WHO criteria for safe consumption of drinking water 500 mBq·kg-1(a) and 1 000 mBq·kg-1(ß).[4] This value can typically be achieved with a counting time of 500 min for a test sample volume of 0,08 l. The method described in this document is applicable in the event of an emergency situation, because the results can be obtained in less than 4 h by directly measuring water test samples without any treatment.

 

This document provides standard procedures for the collection, handling and storage of soil for subsequent biological testing under aerobic conditions in the laboratory. It applies to the collection, handling and storage for assessing the effects of soil on microorganisms, invertebrates (e.g. survival, reproduction, growth, behaviour) and plants (e.g. development, growth). This document is not applicable to the handling of soil where anaerobic conditions need to be maintained throughout. This document describes how to minimize the effects of differences in temperature, water content, and availability of oxygen on aerobic processes as well as the fractionation of soil particles to facilitate reproducible laboratory determinations[1][2]. This document is mainly applicable to temperate soils. Soils collected from extreme climates (e.g. permafrost, tropical soils) can require special handling.
