Polyethylene (PE) materials for piping systems — Determination of Strain Hardening Modulus in relati...
ISO 18488:2015 specifies a method for the determination of the strain hardening modulus which is used as a measure for the resistance to slow crack growth of polyethylene.
The strain hardening modulus is obtained from stress-strain curves on compression moulded samples. This International Standard describes how such measurement is performed and how the strain hardening modulus shall be determined…

Conformity assessment — General requirements for bodies operating certification of persons
ISO/IEC 17024:2012 contains principles and requirements for a body certifying persons against specific requirements, and includes the development and maintenance of a certification scheme for persons.
Life-threatening components of fire — Part 3: Guidelines for the estimation of time to compromised t...
This standard provides guidance for fire safety engineering that is applicable for fires in enclosed spaces. It is intended to be used in conjunction with models for analysis of the initiation and development of fire, fire spread, impact of heat, radiation, and limited visibility, smoke formation and movement, chemical species generation, transport and decay, and people movement, as well as fire…
Glass in building — Determination of thermal transmittance (U value) — Calculation method
Applies to glass, coated glass and materials opaque in the far infrared wavelengths. Gives the fundamental rules for calculating the thermal transmittance in the glazing central area (edge effects are not included). The rules are intended to enable the heat loss through glazing in a building to be estimated from the U values and, together with heat losses through the opaque elements of the…
