This document specifies methods and principles for detection of selected congeners of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated biphenyls (PCBs) in water and wastewater using a flow immunosensor. The flow immunosensor utilizes antibodies specific to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and 3,3’,4,4’,5-pentachlorobiphenyl (3,3’,4,4’,5-PeCB), which have the highest toxic equivalent factor (TEF) value among the congeners of each of PCDDs and PCBs. The method is applicable to timely monitoring of selected congeners of 2,3,7,8-TCDD and 3,3’,4,4’,5-PeCB in water and wastewater to prioritize those for subsequent confirmatory determination. This document specifies practical methods and procedures for sampling, extraction, clean-up, measurement in a flow immunosensor, data processing and validation of measurement results. The combined use of automated instruments for extraction, clean-up, and flow immunosensing can reduce time-consumption and labour-intensity, while providing reproducible precise data. This method can provide the lower limit of quantification (LOQ) for 2,3,7,8-TCDD and 3,3’,4,4’,5-PeCB of 28 pg/l and 152 pg/l, respectively at 20 % or less of coefficient variation (CV) depending on sampling, extraction, clean-up and measurement conditions.

This document specifies the test methods for marine external firefighting systems after installation aboard, mainly including test preparation, test conditions, test apparatus and procedures. This document excludes the performance requirements of the equipment. This document is applicable to the testing of external firefighting systems installed on ships for the purpose of extinguishing fires occurring on other vessels, offshore structures or quayside structures. This document applies to marine external firefighting system with water or foam as the medium.

This document specifies a test method for the determination of puncture impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominal constant striker velocity, is necessary for detailed characterization of the impact behaviour. The test method is applicable to specimens with a thickness between 1 mm to 4 mm. The method is suitable for use with the following types of material: —    rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets; —    rigid thermosetting moulding and extrusion materials, including filled and reinforced compounds, sheets and laminates; —    fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or multi-directional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs). The method is also applicable to specimens which are either moulded or machined from finished products, laminates and extruded or cast sheet. The test results are comparable only if the conditions of preparation of the specimens, their dimensions and surfaces as well as the test conditions are the same. In particular, results determined on specimens of different thickness cannot be compared with one another (see Annex E). Comprehensive evaluation of the reaction to impact stress can be obtained by determinations made as a function of impact velocity and temperature for different material variables, such as crystallinity and moisture content. The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken from finished products (see above) for tests by this method. Test data developed by this method is not intended to be used for design calculations. However, information on the typical behaviour of the material can be obtained by testing at different temperatures and impact velocities (see Annex D) by varying the thickness (see Annex E) and by testing specimens prepared under different conditions. It is not the purpose of this document to give an interpretation of the mechanism occurring on every particular point of the force-deflection diagram. These interpretations are a task for scientific research.
