1 Scope and object This part of IEC 61000-4 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to: a) repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage (HV/MV) substations; b) repetitive damped oscillatory waves occurring…

1.1 General This Standard specifies requirements for a) mortar for use in bedding, jointing, and bonding of masonry units; and b) grout for use in filling core, cell, or cavity space in unit masonry construction. Notes: 1) The term “unit masonry” refers to masonry construction using clay (shale), calcium silicate (sand-lime), or concrete masonry units, with individual units not more than 200 mm…

ISO 18589-7:2013 specifies the identification of radionuclides and the measurement of their activity in soil using in situ gamma spectrometry with portable systems equipped with germanium or scintillation detectors. ISO 18589-7:2013 is suitable to rapidly assess the activity of artificial and natural radionuclides deposited on or present in soil layers of large areas of a site under investigation…

1 Scope and object This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to non-repetitive damped oscillatory transients (ring waves) occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this basic standard is to establish the immunity…

ISO 12110-1:2013 establishes general principles for fatigue testing of laboratory specimens under a sequence of cycles the amplitude of which varies from cycle to cycle. This sequence of cycles is called loading time history (see 3.7) and is usually derived from loading measurements performed on components or structures submitted to true service loadings. Detailed description of service loads…

ISO 23893-3:2013 specifies a method for measuring vitellogenin (Vtg) concentrations in a fish plasma sample employing an enzyme-linked immunosorbent assay (ELISA) method. It applies to fish that are sampled in the environment (fresh, estuarine or salt water) and to fish exposed to substances or effluents in a laboratory. The method is quantitative when using Vtg antibodies and a Vtg standard well…

ISO 340:2013 specifies a method for assessing, on a small scale, the reaction of a conveyor belt to an ignition flame source. It is applicable to conveyor belts having a textile carcass as well as steel cord conveyor belts.

IEC/TS 62850:2013 specifies general safety requirements for the following types of equipment and their accessories intended to be used in educational establishments by persons between the age of 3 years and the age of 16 years under the supervision of the RESPONSIBLE BODY. If all or part of the equipment falls within the scope of one or more part 2 standards of IEC 61010 as well as within the…

ISO 5814:2012 specifies an electrochemical method for the determination of dissolved oxygen in water by means of an electrochemical cell which is isolated from the sample by a gas permeable membrane. Measurement can be made either as a concentration of oxygen in milligrams per litre, percentage saturation (% dissolved oxygen) or both. The method measures oxygen in water corresponding to 1 % to…

This part of ISO 16000 specifies a laboratory test method using test chambers defined in ISO 16000-9 and evaluation procedures for the determination of odours emitted from newly produced building products under defined climate conditions. The method can also, in principle, be applied to aged products. This part of ISO 16000 is applicable to various test chambers used for the determination of…
