BS 5852核心要点：从适用范围到测试的全流程指南

BS5852核心要点：从适用范围到测试的全流程指南BS5852是英国针对软体家具防火性能的核心标准，涵盖软垫座椅或整套座椅中使用的椅套和填充物的阻燃测试要求。为确保产品顺利通过认证并符合市场准入条件，企业在申请过程中需重点关注以下事项，涵盖产品分类、测试流程、材料合规性等关键环节。一、明确产品适用范围与分类适用产品类型：BS5852主要适用于软体家具，包括沙发、床垫、座椅、靠垫等，需常见家居用品，特殊场景：户外家具若用于室内（如篷车、花园家具），仍需符合标准豁免产品：床单、地毯、独立填充物等不属于测试范围严格遵循测试火源BS5852标准针对软座整个家具，划分为7个点火源。客户可根据产品使用场景和合规要求，选择对应的点火源进行检测。针对软体家具所有组成材料，需根据标准中指定的点火源进行试验。火源类型包括香烟和模拟火柴、5号小木架、2号丁烷火源。三、豁免条件天然纤维豁免：若织物中棉、羊毛、亚麻等天然纤维占比超过75%，且未经阻燃涂层处理，可免测部分火源，但需通过夹层材料测试填充物要求：聚氨酯泡沫需通过Schedule1测试，乳胶泡沫需通过PartIII测试；混合填充物需单独或组合测试四、测试流程选择认证实验室提交申请表：明确产品信息、测试火源及适用条款报价与合同：实验室根据测试项目出具报价单，确认后签订合同
