It shall be free of visible defectssuch as holes, ragged or untrue edges, breaks, cracks, tears,protuberances, and indentations, except for those perforationsor protuberances which are intentional.4.3 The surface of the underlayment sheet shall be designedto provide traction and slip

It is the further intent of this
43、 paragraph to ensurethat, whatever method is used, the friction coefficient or resistance toslipping of the surface of these products should be at least as great asasphalt-saturated felt shingle underlayment tested under the same condi-tions of temperature and wetness as agreed between purchaser and
