This International Standard specifies a method for the determination of polychlorinated biphenyl (PCB) concentration in non-halogenated insulating liquids by high-resolution capillary column gas chromatography using an electron capture detector (ECD). The method gives the total PCB content and is especially useful when a detailed analysis of PCB congeners is necessary. Other methods, such as IEC 60997, may be used when a less detailed analysis is acceptable. The method is applicable to unused, reclaimed (including dechlorinated and chemically and/or physically treated), or used insulating liquids contaminated by PCBs.

1.1 These practices cover sampling of new electrical insulating liquids including oils, askarels, silicones, and synthetic liquids as well as such liquids in service or subsequent to service in cables, transformers, circuit breakers, and other electrical apparatus. This test method shall apply to liquids having a viscosity of less than 3000 SUS (Saybolt Universal s) (647.3 cSt) and 100176F (37.8176C). 1.2 The values stated in inch-pound units are to be regarded as the standard. 1.3 Sampling procedures using syringe-type devices, tin plated steel cans with flexible sides and stainless steel cylinders are described in Methods D3613. This method describes preferred techniques to use when sampling for dissolved gas analysis and water content in insulating fluid. 1.4 The procedures appear in the following order: Procedure Section/Paragraph Dip-Type Device 6.2, 13, and X1.1 Pressure-Type Device 6.3, 14, and X1.2 Tank Car-Type Device 6.4, 15, and X1.3 Manifold-Type Device 6.5, 20, and X1.4 Electric Equipment Sample Outlet 6.6 and 18 1.5 Handle askarels as outlined in ANSI C107.1 to avoid environmental contamination. For methods of testing askarels see Methods D901. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.> Specific precautionary statements are given in 12.7, 14.2, Section 17, 19.2, and 21.2.3.

This test method covers the measurement of the ferrimagnetic resonance linewidth and gyromagnetic ratio of isotropic microwave ferrites. This test is restricted to spherical specimens possessing resonance linewidths greater than 10 Oe [796 A/m]. The values and equations stated in customary (cgs-emu and inch-pound) or SI units are to be regarded separately as standard. Within this standard, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
