This European Standard describes the method to evaluate the performance of protective sys-tems for electrical cable and busbar systems in order to maintain the circuit integrity under fire conditions to classify the protective system according to EN 13501-3 for the P classification. The test...
This European Standard specifies a test method to evaluate the maintenance of circuit integrity of electric cables which have intrinsic resistance to fire under fire conditions, in order to classify the electric cable according to EN 13501-3. The test determines the survival time for...
This part of IEC 62839 specifies the PSR (product specific rules) for wires and cables used for communication, data, control and command. This PSR covers the use, installation and end-of-life stages and provides methodological precisions to PEP/PCR writing for "wires and...

4.1 The selection of particular method(s) for drilling monitoring wells (see Table 1) requires that specific characteristics of each site be considered. These characteristics would include, but are not limited to, the ambient hydrogeologic parameters and conditions existing at the site. This guide...
Direct push LIF is used for site investigations where the delineation of petroleum hydrocarbons and other fluorophores is necessary. Generic terms for these investigations are site assessments and hazardous waste site investigations. Continuous LIF is used to provide information on the relative...
