Product Code:SAE J388 Title:Dynamic Flex Fatigue Test for Slab Polyurethane Foam Issuing Committee:Textile And Flexible Plastics Committee Scope: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 1hr recovery period following dynamic fatigue to determine loss in foam thickness.【英文标准名称】:StandardforSafetyforWaterBasedAgentFireExtinguishers 【原文标准名称】:水基试剂灭火器的安全标准 【标准号】:ANSI/UL8CAN/ULC-S554-2007 【标准状态】:作废 【国别】:美国 【发布日期】:2007 【实施或试行日期】: 【发布单位】:美国国家标准学会(US-ANSI) 【起草单位】:ANSI 【标准类型】:() 【标准水平】:() 【中文主题词】:设计;灭火器;灭火器具;泡沫灭火系统;防火安全;燃烧试验;材料;规范(验收) 【英文主题词】:Design;Fireextinguishers;Fireextinguishingapparatus;Fireextinguishingfoamsystems;Firesafety;Flametest;Materials;Specification(approval) 【摘要】:The8/11/06proposalbulletinincludesrevisionsto:operatingtemperaturerequirements;operationtestrequirements;dischargerangetestrequirements;andtemperatureandhumidityrequirementsforthenameplateexposureandadhesiontests. 【中国标准分类号】:C84 【国际标准分类号】:13_220_10 【页数】: 【正文语种】:英语
