Standard Specification for Allowable Defects in Rolled Goods for Interior Trim

2022-01-28
CURRENT
J3064_202201
This specification is written for rolled goods used for trim sets for automotive seats. Face materials are fabric-woven or knitted textiles, and plastic goods like polyvinyl chloride (PVC), thermoplastic polyolefin (TPO), or thermoplastic polyurethane (TPU). This specification covers material rolled goods with and without foam or backing adhered to the face material.

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.

Test Method for Determining Blocking Resistance and Associated Characteristics of Automotive Trim Materials

2023-02-20
CURRENT
J912_202302
This test method is designed to indicate the degree of surface tackiness, color transfer, loss of embossment, and surface marring when two trim materials are placed face to face under specific conditions of time, temperature, and pressure. These specific conditions are not dictated in this test procedure but will be found in the material standards which govern each type of trim material to be tested.
