Tests on electric and optical fibre cables under fire conditions - Part 3-23: Test for vertical flam...
IEC 60332-3-23:2018 covers category B for methods of test for the assessment of vertical flame spread of vertically-mounted bunched wires or cables, electrical or optical, under defined conditions.
This document relates to cables installed on the test ladder to achieve a nominal total volume of non-metallic material of 3,5 l/m of test sample. The flame application time is 40 min. The method of…
Plastics — Determination of viscosity using a falling-ball viscometer — Part 1: Inclined-tube method
This document specifies the general principles of a method, using an inclined‑tube falling‑ball viscometer, for determining the viscosity of polymers and resins in the liquid emulsified or dispersed state. It is intended for application to liquids over a viscosity measurement range of 0,6 mPa·s to 250 000 mPa·s (temperature range −20 °C to +120 °C) for which the shear stress and shear rate are…
Buildings and civil engineering works — Sealants — Specifications for test substrates
This document specifies the procedures for producing substrates of mortar, glass and anodized aluminium used for testing sealants.
The purpose of these requirements is to ensure the reproducibility of the standardized tests conducted on sealants through the precise definition of both the composition and the method of preparation of the test substrates.
The substrates defined in this document are…
Cable networks for television signals, sound signals and interactive services - Part 113: Optical sy...
IEC 60728-113:2018 is applicable to optical transmission systems for broadcast signal transmission that consist of headend equipment, optical transmission lines, in-house wirings and system outlets. These systems are primarily intended for television and sound signals using digital transmission technology. This document specifies the basic system parameters and methods of measurement for optical…
