83.100 - Cellular materials

This document specifies a small-scale laboratory screening procedure for comparing the relative burning characteristics of horizontally oriented, small cellular plastic specimens having a density less than 250 kg⋅m−3 determined in accordance with ISO 845, when exposed to a small-flame ignition source. NOTE Another International Standard which covers flexible cellular plastic and cellular rubber is ISO 3582[2]. This method of test is intended for quality assurance and limited product evaluation o...view more

This document specifies a procedure of determining the shear strength of rigid cellular plastics. It also provides for the determination of shear modulus and shear strain.

ISO 4898:2018 specifies requirements and methods of testing for three categories of rigid cellular plastics thermal-insulation products for buildings. It covers rigid cellular plastics in the form of flat or profiled boards, with or without natural skins. They can also be faced or laminated with foil, plastic or metal films or sheets, mineral coatings, paper, cardboard or other materials.
ISO 4898:2018 is not applicable to materials used for the thermal insulation of pipes and vessels, for impa...view more

This standard specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both open- and closed-cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials w...view more

This document specifies the minimum requirements for flexible polyurethane foams up to and including 20 mm thick intended for combination with suitable substrates such as non-woven, woven or knitted fabrics, to form a laminate. Three types of flexible polyurethane foam are specified as follows: — type 1: polyether; — type 2: polyester with minimum elongation at break of 200 %; — type 3: polyester with minimum elongation at break of 300 %.

This document specifies a method for determining the resilience by ball rebound of flexible cellular
polymeric materials.

This document specifies three methods for determining the compression set of flexible cellular
materials.
This document applies to latex and polyurethane foams of thickness greater than 2 mm.

This document specifies two methods for the determination of the tear strength of flexible cellular
polymeric materials:
— method A, using a trouser test piece;
— method B, using an angle test piece without a nick.

This International Standard specifies a general procedure for the determination of the volume
percentage of open and of closed cells of rigid cellular plastics, by measurement first of the geometrical
volume and then of the air-impenetrable volume of test specimens.
The procedure includes the correction of the apparent open-cell volume by taking into account the
surface cells opened by cutting during specimen preparation. Three alternative methods (method 1,
method 2a and method 2b), and co...view more
