BS5852核心要點(diǎn)：從適用范圍到測(cè)試的全流程指南BS5852是英國(guó)針對(duì)軟體家具防火性能的核心標(biāo)準(zhǔn)，涵蓋軟墊座椅或整套座椅中使用的椅套和填充物的阻燃測(cè)試要求。為確保產(chǎn)品順利通過(guò)認(rèn)證并符合市場(chǎng)準(zhǔn)入條件，企業(yè)在申請(qǐng)過(guò)程中需重點(diǎn)關(guān)注以下事項(xiàng)，涵蓋產(chǎn)品分類(lèi)、測(cè)試流程、材料合規(guī)性等關(guān)鍵環(huán)節(jié)。一、明確產(chǎn)品適用范圍與分類(lèi)適用產(chǎn)品類(lèi)型：BS5852主要適用于軟體家具，包括沙發(fā)、床墊、座椅、靠墊等，需常見(jiàn)家居用品，特殊場(chǎng)景：戶(hù)外家具若用于室內(nèi)（如篷車(chē)、花園家具），仍需符合標(biāo)準(zhǔn)豁免產(chǎn)品：床單、地毯、獨(dú)立填充物等不屬于測(cè)試范圍嚴(yán)格遵循測(cè)試火源BS5852標(biāo)準(zhǔn)針對(duì)軟座整個(gè)家具，劃分為7個(gè)點(diǎn)火源。客戶(hù)可根據(jù)產(chǎn)品使用場(chǎng)景和合規(guī)要求，選擇對(duì)應(yīng)的點(diǎn)火源進(jìn)行檢測(cè)。針對(duì)軟體家具所有組成材料，需根據(jù)標(biāo)準(zhǔn)中指定的點(diǎn)火源進(jìn)行試驗(yàn)。火源類(lèi)型包括香煙和模擬火柴、5號(hào)小木架、2號(hào)丁烷火源。三、豁免條件天然纖維豁免：若織物中棉、羊毛、亞麻等天然纖維占比超過(guò)75%，且未經(jīng)阻燃涂層處理，可免測(cè)部分火源，但需通過(guò)夾層材料測(cè)試填充物要求：聚氨酯泡沫需通過(guò)Schedule1測(cè)試，乳膠泡沫需通過(guò)PartIII測(cè)試；混合填充物需單獨(dú)或組合測(cè)試四、測(cè)試流程選擇認(rèn)證實(shí)驗(yàn)室提交申請(qǐng)表：明確產(chǎn)品信息、測(cè)試火源及適用條款報(bào)價(jià)與合同：實(shí)驗(yàn)室根據(jù)測(cè)試項(xiàng)目出具報(bào)價(jià)單，確認(rèn)后簽訂合同
