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.

J1774_201006
This document provides information on the various fiberboard products, which are available for automotive application. It is intended to give engineers and designers a better understanding of product usage, characteristics, properties and industry terminology. The following sections cover these topics: 2 General Product Information 3 Design Characteristics 4 Physical/Mechanical Properties 5 Fiberboard Definitions In sections 2, 3 and 4 the fiberboard products are categorized. These sections give an overview of product types, with general information about characteristics and properties. In cases where product categories encompass more than one material or material grade, ranges were established to cover all of the products in that category. The individual companies that supply fiberboard products should be consulted for specific information about a particular product or application.

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.
