This document defines the procedures for classifying, testing and labelling of cartridges for powder actuated tools (PAT cartridges), as defined in Clause 3 of this document. This document applies to PAT cartridges which are all classified as P1. This document does not apply to pyrotechnic articles containing blasting agents and military explosives except black powder and flash composition. PAT cartridges contain pyrotechnic composition(s) delivering mainly gases, intended to propel a piston. The piston propels fasteners (e.g. nails) or drives hard marking characters into appropriate materials. This document also applies to PAT cartridges sold to persons younger than 18 years, if this is permitted by the Member State due to the low hazard of the PAT cartridges. NOTE PAT cartridges can also be used for hard marking tools. Information on cartridge operated fixing and hard marking tools can be found in EN 15895:2025 [1]. This document applies to the cartridges listed in Table 1. Table 1 — Lists of the established calibres for PAT cartridges

This document specifies a method for the measurement of 99Tc in all types of water by inductively coupled plasma mass spectrometry (ICP-MS). The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling and test sample preparation. A filtration of the test sample is necessary. The detection limit depends on the sample volume and the instrument used. The method described in this document, using currently available ICP-MS, has a detection limit of approximately 0,2 ng·kg-1 to 0,5 ng·kg-1 (0,1 Bq·kg-1 to 0,3 Bq·kg-1), which is much lower than the WHO criteria for safe consumption of drinking water (100 Bq·l-1)[3]. The method presented in this document is not intended for the determination of ultra-trace amount of 99Tc. The mass concentration values in this document are expressed by sample mass unit instead of sample volume unit as it is usually the case in similar standards. The reason is that 99Tc is measured in various matrix types such as fresh water or sea water, which have significant differences in density. The mass concentration values can be easily converted to sample volume unit by measuring the sample volume. However, it increases the uncertainty on the mass concentration result. The method described in this document is applicable in the event of an emergency situation, but not if 99mTc is present at quantities that could cause interference. The analysis of Tc adsorbed to suspended matter is not covered by this method. It is the user's responsibility to ensure the validity of this test method for the water samples tested.
