A number in parentheses indicates the year of last reapproval. Certain irregularsurfaces may not be evaluated properly by this test methodbecause of wear patterns. No other units of measurement are included in thisstandard. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

Referenced Documents2. Significance and Use3. A staining agentin light oil may be used to help determine whether abrasionsurface is likely to result in mechanical entrapment of dirtparticles. Abrasive Load4. Reagents and Apparatus5. Thedistance between the center of each position shall be mm. There shall be equal distance between each adjacent position. Thetest specimens are held down with the aid of metal holders,which are provided with rubber seals see Fig.

The internaldiameter of the holders is 83 mm, thus providing a test area ofabout 54 cm2. The thickness of the rubber is 2. The apparatusswitches off automatically after completion of a preset numberof revolutions.

The supporting plate with holders and testspecimens should have a cover during operation. The interior of thebox shall be painted a neutral gray. Current edition approved Dec. Published February Originallyapproved Last previous edition approved in as C — 99 United States1FIG. Test Specimen6.

Where tiles have different colors ordecorative effects in parts of the surface, care should be takento include all distinctive parts. Test specimens with smaller facial dimensions shall befastened close together on a suitable supporting material. Edgeeffects at the narrow joints shall be ignored. Eight test specimens also are required for the visualassessment. The procedure requires one test specimen for eachstage of abrasion, and subsequently, an additional three testspecimens to verify the result at the visual fail point.

Introduce the abrasive load, as described in Section 4, into theholder through the hole in its upper surface.

The hole may besealed to prevent loss from the abrasive load. The number ofrevolutions of the preset counter for each abrasion stage of thetest is , , , , , , , and 12 The eight unabraded tile should be cleaned with asoft damp cloth to remove surface dust and after air dryingshould be placed in a hollow square pattern in the viewing box.

The arrayshould not be viewed for more than 10 s to avoid a studiedobservation of the surface. The lowest number of abradingcycles that show an apparent visual difference between theabrading tile and the unabraded tile shall be recorded. If the result is not the same, the lower of thetwo abrasion stages shall be used to decide the classification. Abraded tiles, which have passed , , and revolution stages subsequently may be tested for stain resis-tance in accordance with the staining procedure in 7.

The abraded tile which has passed the 12 revolutions stage,subsequently shall be tested for stain resistance in accordancewith the staining procedure in following section based on ISO NOTE 1—Box 61 by 61 by 61 cm.

Plan 61 by 61 cm. Light sourcescreened to avoid direct viewing, lux illumination on the tiles, innerfaces of box painted gray. Allow the stainingagent to remain in contact with the abraded tile surface for 24h. The specimens areinspected at a distance of 25 to 30 cm.

Daylight or artificialillumination is permitted at approximately lux, but directsunlight shall be avoided. Staining only shall be reported whenthe pigments are visible. A natural, nonabrasive sponge or a clothcan be used.

The surface then is rinsed with running water andfinally wiped with a damp cloth. The cleaning action is applied for approximately 2min and then the surface is rinsed with running water andfinally wiped with a damp cloth. Classification of Results8. To be classified as Class V, the tile also must pass the stainingprocedure in Section 6.

If there isno visual failure at 12 revolutions, but the stain cannot beremoved by any of the procedures listed in 6. Precision and Bias The sole source of supply of Myritol known to the committee at this time isHenkel Corp.
