5. The length of rolls of finished wallpaper shall be 11 ½ yards subject to a tolerance of ±1 ½ per cent.


6. The length of borders when supplied in rolls shall be 9 yd., or 12 yd., and when supplied in coils shall be 12 yd., or multiples of 12 yd, These lengths shall be subject to a tolerance of ±1 ½ per cent.


7. Finished wallpaper shall be free from blemishes and roller defects.

Test pieces shall be not less than 10 in. by 10 in. in size and shall be taken from the rolls at a position not less than 1 yard from the end of the roll, and not less than 1 inch from the edge. The test pieces shall be so cut that the edges are exactly parallel to the machine and cross directions of the paper.

Test pieces of borders shall be not less than 10 in. long and the full width of the border. They shall be taken at not less than one yard from the end of the coil.

The test samples shall be kept flat, free from wrinkles or folds, and shall be protected from exposure to liquids, direct sunlight, or other harmful influences.


11. Tests on finished wallpaper shall be carried out in a room maintained at a temperature of 28° C. ± 1.7° C., and a relative humidity of 65.±2.0 per cent. Arrangements shall be provided for circulating the air in the room so that its temperature and relative humidity shall be uniform.

The test pieces of finished wallpaper to be tested shall be dried at a temperature of 55° C. to 60° C., over a saturated solution of calcium chloride and then suspended so that the atmosphere of the room has access to all the surface of the paper. Before testing, the paper shall be weighed at intervals of one half-hour until the weight is found to be constant.

The relative humidity of the atmosphere of the room shall be determined by means of wet-and-dry bulb thermometers placed in an air current having a velocity of at least three metres per second. The thermometers shall be graduated to the nearest 0·5° C., and shall be matched to within 0·25° C. throughout their range. They shall be compared with a certified thermometer before using and the necessary corrections applied.


Determination of Substance

Ten test pieces shall be tested. Each test piece shall be weighed either on a beam scales or an automatic scales. The scales shall be sensitive to at least 0·25 per cent. of the load applied and shall be protected from air currents. If an automatic scales is used, it shall be checked before use both with increasing and decreasing loads made up of accurate weights.

The weight in oz. per roll, 22 in. wide and 12 yd. long shall be determined for each test piece and the average weight per roll of the ten test pieces shall be calculated to two places of decimals. This average weight shall be taken as the substance of the paper.

GIVEN under my Official Seal, this 14th day of December, 1953.
