Note: The ICS Code for this NOI (originally published on May 4, 2021) was updated by the responsible SDO on December 5, 2023.

Note: The title, standard designation, scope, and project need for this NOI (originally published on May 4, 2021) was updated by the responsible SDO on August 9, 2023.

 

This National Standard of Canada:

  • determines the flame resistance of soft floor coverings when exposed to an ignition source (methenamine for timed burning tablet) under specified conditions.
  • establishes sampling plans and procedures to determine the acceptability with respect to the flame resistance of soft floor coverings using a sequential sampling procedure.
  • describes a procedure for the removal, prior to testing for flame resistance, of non-permanent flame-retardant treatments applied to soft floor coverings.

It is applicable to all types of soft floor coverings, regardless of fibre type or method of construction.

Project need:

CAN/CGSB-4.2 No. 27.6-2015 Flame resistance — Methenamine tablet test for textile floor coverings, CAN/CGSB-4.2 No. 30.2-M90 Procedure for the removal of non-permanent flame retardants on textile floor coverings and CAN/CGSB-4.155-M88 Flammability of soft floor coverings — Sampling plans were combined into a single standard. - Definition of “charring/charred” added. - Definitions for “inspection” and “unacceptable product level” removed. - Specifications for the roller are explicitly stated, removing reference to CGSB-22.42 Paint Rollers and Accessories. - Section 6 was added to outline how the samples are sampled, prepared and tested. - A numerical value for still-air conditions was added. - Conditioning requirements prior to testing are now explicitly stated. Previously, these conditions were referenced in CAN/CGSB-4.2 No. 2 – Conditioning Textile Materials for Testing. - Use of deionized water during washing is now permitted. - The default desiccant was changed to anhydrous silica gel. Use of other equally effective desiccants is still permitted.
