DYNAMIC FLEX FATIGUE TEST FOR SLAB POLYURETHANE FOAM
1969-03-01
HISTORICAL
J388_196903
This SAE Recommended Practice describes a laboratory test procedure for evaluating the loss of thickness and the amount of structural breakdown of slab polyurethane foam seating materials. A test specimen is measured for thickness under a specified load and subsequently subjected simultaneously to compressive and shear deformation in a controlled atmosphere. This is accomplished by subjecting the foam to a rolling shearing action under a constant load for a specified number of cycles. Specimen thickness under a constant load is obtained after a 1 hr recovery period following dynamic fatigue to determine loss in foam thickness.

Fiberboard Crease Bending Test
2010-05-10
HISTORICAL
J119_201005
This test method is designed to determine the suitability of a painted or unpainted fiberboard for application involving creasing and bending. The specific purpose of the test is to determine whether a given material, properly creased, can be bent along the impressed crease without objectionable failure on the surface of the bend.

LOAD DEFLECTION TESTING OF URETHANE FOAMS FOR AUTOMOTIVE SEATING
1994-01-01
HISTORICAL
J815_199401
Cellular foam products have been traditionally checked for load deflection by determining the load required to effect a 25% deflection. In seating, on the other hand, the interest is in determining how thick the padding is under the average passenger load (a measurement of padding left for "ride" and seated height), a second measurement to give an indication of initial softness, and a final figure to indicate resiliency. To most easily fulfill these requirements, load deflection on flexible urethane foams for automotive seating is determined here by measuring the thickness of the pad under fixed loads of 1 lb, 25 lb, and 50 lb on a 50 in2 circular indentor foot.

Load Deflection Testing of Urethane Foams for Automotive Seating

HISTORICAL
J815_200708
Traditionally, cellular foam products have been checked for load deflection by determining the load required to cause a 25% deflection. In automotive seating, on the other hand, the load deflection is checked by determining the thickness under constant force conditions to (a) indicate the initial softness of the seat cushion, (b) measure how thick the seat cushion is under the average passenger load (a measurement of padding left for “ride” and seated height), and (c) determine a value to indicate resiliency. In this method these measurements are made by determining the thickness of the seat cushion under fixed loads of 4.5 N, 110 N, and 220 N with a 323 cm2 circular indentor foot.
