Frequently Asked Questions

CEN/TC 249/SC 1/WG 10 is a Subcommittee within the European Committee for Standardization (CEN). It is named "Polyamides". This committee has published 6 standards.

CEN/TC 249/SC 1/WG 10 develops CEN standards. Currently, there are 6 published standards from this subcommittee.

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.

A Subcommittee (SC) in CEN operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.

Plastics - Polyamides - Accelerated conditioning of test specimens (ISO 1110:2019)
SIST EN ISO 1110:2019

This document describes a method for the accelerated conditioning of test specimens of polyamides and copolyamides. It is applicable to grades containing fillers and other additives, but not grades containing more than a mass fraction of 2 % extractables.
The equilibrium moisture content attained by this method is close to the equilibrium moisture content obtained in standard atmosphere 23 °C/50 %RH. The values of mechanical properties obtained after accelerated conditioning in accordance with this method can differ slightly from those obtained after conditioning in standard atmosphere 23 °C/50 %RH.

EN ISO 1110:1997(Main)
Plastics - Polyamides - Accelerated conditioning of test specimens (ISO 1110:1995)
SIST EN ISO 1110:1999

The method described is based on storing the test specimens in an atmosphere of (70 ± 1) °C and (62 ± 1) % relative humidity (psychrometric temperature difference of (10 ± 0,3) °C), until moisture absorption by the specimen has reached at least 95 % of its equilibrium level. It is applicable to polyamides and copolyamides in grades containing fillers and other additives, but not to grades containing more than 2 % (m/m) extractables. The equilibrium moisture content attained is close to the equilibrium moisture content obtained in standard atmosphere 23/50.
