This document specifies a test method for atmospheric corrosion measurements, using two-electrode electrochemical sensors. It is applicable to measurements of the corrosion rate of uncoupled metal surfaces (i.e. "free" corrosion rate), galvanic corrosion rate, conductance of thin film solutions and barrier properties of organic coatings. It specifies electrochemical sensors that are…

1. Scope 1.1 This Standard provides requirements for polyolefin laboratory drainage systems from corrosive applications. Requirements for materials, pipe, and fittings are included. Note: Polyolefin includes both polyethylene and polypropylene plastics. 1.2 These requirements apply to pipe and fittings that are to be joined by heat fusion using the joining equipment supplied by the…

This document specifies two procedures for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature. The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one. Two test methods…

IEC 61094-8:2012 applicable to working standard microphones meeting the requirements of IEC 61094-4. It describes methods of determining the free-field sensitivity by comparison with a laboratory standard microphone or working standard microphone (where applicable) that has been calibrated according to either; IEC 61094-3; IEC 61094-2; IEC 61094-5; IEC 61094-6; or this part of IEC 61094. Methods…

IEC/TR 62283:2010(E) gives a short summary of the radiation exposure in certain environments and applications and the different radiation effects on fibres. It also describes the most important radiation effect, i.e. the increase of transmission loss, and its strong dependence on a variety of fibre properties and test conditions. These dependencies need to be known in order to perform appropriate…

ISO 16232-5:2007 describes the principles of extraction of contaminants by test on a laboratory functional test bench with the test liquid flowing under pressure or under vacuum. It is applicable to both active and passive components through which the fluid can easily flow. Unless otherwise specified, ISO 16232-5:2007 deals with particulate contamination only. It does not, therefore, cover…

This document provides voluntary performance targets for cookstoves and is intended to supplement ISO 19867-1. These voluntary performance targets are intended for use with the results of the laboratory testing specified in ISO 19867-1. These voluntary performance targets are provided as informative guidance, and are not intended as normative requirements for the testing of cookstoves.…

ISO 6914:2013 describes three methods for the measurement of the change of stress in a test piece at a given elongation for the purpose of determining the ageing characteristics of a rubber. Method A is intended for measurement under continuous strain conditions. Method B is the preferred method for measurement under intermittent strain conditions. In the case of both methods A and B, a…

ISO 20340:2009 deals with performance requirements for protective paint systems for offshore and related structures (i.e. those exposed to the offshore environment, as well as those immersed in sea or brackish water). It can also be used for other structures, provided that the paints or protective paint systems selected comply with ISO 20340. ISO 20340 includes: the test methods to be used to…
