ISO 10555-3:2013 specifies requirements for central venous catheters supplied in the sterile condition, and intended for single use.

 

This document applies to uniaxial strain-controlled low cycle fatigue testing of metallic materials governed by EN aerospace standards. It defines the properties that need to be determined and the terms used in describing the tests and test pieces. It specifies the equipment, the test pieces, the method of testing and the presentation of results. It applies to testing at ambient and elevated temperatures. The purpose of this document is to ensure the comparability and reproducibility of the test results. It does not cover the evaluation or interpretation of the results. This document is restricted to the use of test pieces having a circular cross-section. In some particular cases the practice can be applied to flat test pieces. The major difficulties concern the preparation of the test pieces and their alignment in the grips.

 

This document specifies methods used to determine the concentration of plutonium and neptunium isotopes in water by inductively coupled plasma mass spectrometry (ICP-MS) (239Pu, 240Pu, 241Pu and 237Np). The concentrations obtained can be converted into activity concentrations of the different isotopes[9]. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify this isotope, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167[10], is currently used[11]. This method is applicable to all types of water having a saline load less than 1 g·l-1. A dilution of the sample is possible to obtain a solution having a saline load and activity concentrations compatible with the preparation and the measurement assembly. A filtration at 0,45 µm is needed for determination of dissolved nuclides. Acidification and chemical separation of the sample are always needed. The limit of quantification depends on the chemical separation and the performance of the measurement device. This method covers the measurement of those isotopes in water in activity concentrations between around[12][13]: — 1 mBq·l-1 to 5 Bq·l-1 for 239Pu, 240Pu and 237Np; — 1 Bq·l-1 to 5 Bq·l-1 for 241Pu. In both cases, samples with higher activity concentrations than 5 Bq·l-1 can be measured if a dilution is performed before the chemical separation. It is possible to measure 241Pu following a pre-concentration step of at least 1 000.
