16、d iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bodyinterested in a subject for which
17、 a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closelywith the International Electrotechnical Com mission (IEC) on all matt
18、ers of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft Internationa l Standardsadopted by the technical committees are circula
19、ted to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsibl
20、e for identifying an y or all such patent rights. ISO 26987 was prepared by Technical Committee ISO/TC 219, Floor coverings.

21、nce to chemicals1 Scope This International Standard specifies a procedure for the determination of the reaction of resilient floorcovering to chemical substances. 2 Principle Various chemical substances in liquid or paste form are placed on a test piece for defined periods and thenremoved. After cle
22、aning has been carried out, the resulting change of appearance is assessed under specifiedlighting conditions.3 Apparatus and materials 3.1 Standard laboratoryequipment. 3.1.1 Pipettes.3.1.2 Watchglass, diameter 40 mm.3.1.3 Spatulas. 3.2 Chemical substances in liquid or paste form. This Internationa
23、l Standard does not specify or suggest the chemical substances to be tested. 3.3Standard cleaning and stain removal products. 3.3.1 White cotton, in pad or cloth form. 3.3.2 Brushes, hard, unlikely to score the surface. 3.3.3 Warm water, used alone or with selected cleaning products (see Annex A). 3
24、.4 Abrasivematerials (abrasives, abrasive scouring pads, steel wool No. 00 or scouring powder, orabrasive papers, grain size P 240 or finer, used withwater).3.5Special cleaning products,recommended by the floor covering manufacturer.3.6 Illumination device , comprising a lamp of correlated colour te
25、mperature 5 500 K to 6500 K, mountedto give an intensityof light at the viewing platform of (1 500 100) lx and in such away as to illuminate thetest piece vertically from above. The surroundings shall be neutral and darkened. The intensity of the light shall be checked frequentlybythe use of a luxom
26、eter. The lifetime of the lamp, asgiven by the manufacturer, shall not be exceeded.

27、pling and preparation of test piece Take a representative sample from the available floor covering material. The sample should be obtained froma new roll or carton and should not have been treated with any floor finish/polish.Take one test piece in each colour to be testedwith a surface area of at l
28、east 3 000 mm2 , for each of thechemical substances to be tested. If the test uses a chemical substance likely to cause swelling ordeformation of the test piece, e.g. prolonged contact with the solvent, bond the test piece to a fibre-cementboard at least 5 days before testing. Identify the test piec
29、es corresponding to each of the substances tested, either bymarking numbers on the testpiece (using a marking which is not affec ted by the material used in the test),or b y a sketch, diagram orphotograph. 5 Atmosphere for conditioning and testing Condition the test pieces at a temperature of (23 2)
30、 C and a relative humidity of(50 5) % for a minimumof 24 h. Maintain this condition when carrying out the test. 6 Test procedure 6.1Application of liquid substances 6.1.1 Using a clean pipette(3.1.1), pour a small quantityof the liquid chemical substance to test (see 3.2) into the centre of the mark
31、ed position of the testpiece. Apply the convex face of a watch glass (3.1.2) to the liquidand remove it immediately. If the diameter of the splash of the liquid chemical substance is more than 15 mm,apply the watch glass again. Leave it in position this time, in such a way as to produce a splash of
32、liquidchemical substance covering an area of 300 mm2 to 400 mm2 . 6.1.2 If the diameter of the chemical substance does not exceed 15 mm, add a few more drops and spreadit again by applying the watch glass. Leave it in position this time, in such a way as to produce a splash of the liquid chemical su
33、bstance of 300 mm2 to 400 mm2 . 6.2Application of paste substances With a spatula (3.1.3), spread about 1 000 mm3 of the paste chemical substance to test (see 3.2) over an areaof 300 mm2 to 400 mm2 (i.e. thickness 2,5 mm to 3 mm). 6.3Duration of contactThe main duration of contact shall be 2 h with
34、the evaluation of the sample being done within 5 min ofremoving the chemical substance. After cleaning and observationif the test piece has been adversely affected (staining, dulling, softening, swelling, etc.),a new test shall be conducted for a period of 30 min. 6.4Cleaning and observation 6.4.1 B
35、efore cleaning, remove chemical substances which are still liquid with cotton (3.3.1),working fromthe edge towards the centre of the stain. Scrape off the remains of paste with a spatula (3.1.3) and wipe withcotton as above. Clean the surface, working from the edge toward the centreof the stain, usi

After cleaning has been carriedout, examine the residual staining using the illumination device (3.6) from a distance of approximately 800 mmat
37、an approximate angle of 45 degrees and from all dire ctions by slowly rotating the viewing table (3.7).6.4.2 If a stain is still visible, rub it down with anabrasive material (see 3.4) or a cleaning product recommended by the manufacturer (3.5), and examine it as described in 6.4.1. 7 Expression of
