Description / Abstract:

This Standard specifies the general methods of testing of continuous glass fibres and products made of continuous glass fibres such as glass fabrics and glass mats (hereafter generically referred to as "fabrics" and "mats" respectively).

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 1887 : 1995 Textile glass - Determination of combustible-matter content

ISO 1888 : 2006 Textile glass - Staple fibres or filaments - Determination of a verage diameter

ISO 2558 : 2010 Textile glass chopped-strand mats for reinforcement of plastics - Determina tion of time of dissolution of the binder in styrene

ISO 2559 : 2011 Textile glass -Mats {made from chopped or continuous strands} - Designation and basis for specifications

ISO 3341 : 2000 Textile glass - Yarns - Determination of breaking force and breaking elongation

ISO 3342 : 2011 Textile glass -Mats -Determination of tensile breaking force

ISO 3343 : 2010 Reinforcement yarns - Determination of twist balance index

ISO 3374 : 2000 Reinforcement products - Mats and fabrics - Determina tion of mass per unit area

ISO 3375 : 2009 Textile glass -Determination ofstiffness ofrovings

ISO 3616 : 2001 Textile glass - Chopped-strand and continuous-filament mats - Determination of average thickness) thickness under load and recovery after compression

ISO 4602 : 2010 Reinforcements - Woven fabrics - Determination of number of yarns per unit length of warp and weft

ISO 4603 : 1993 Textile glass - Woven fabrics - Determination of thickness

ISO 4604 : 2011 Reinforcement fabrics - Determination of conventional flexural stiffness - Fixed-angle flexometer method

ISO 4606 : 1995 Textile glass - Woven fabric -Determination of tensile breaking force and elongation at break by the strip method

ISO 4900 : 2011 Textile glass - Mats and fabrics - Determination of contact mouldability

ISO 5025 : 1997 Reinforcement products - Woven fabrics - Determination of width and length (overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.


Persons carrying out tests based on this Standard should be familiar with normal laboratory practice. This Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices.
