Sofas yog cov khoom siv tseem ceeb hauv kev lag luam rooj tog, nrog rau qhov ntim loj thiab kev faib tawm dav. Cov qauv no yog kev kho dua ntawm QB / T1952.1-1999, nrog cov kev hloov pauv tseem ceeb hauv qab no piv rau tus qauv qub:
1. Kev faib khoom lag luam: Cov txheej txheem no cais cov khoom lag luam feem ntau raws li lub rooj zaum elastic khoom, upholstery, thiab kev ua haujlwm.
2. Cov Lus Qhia Tseem Ceeb: Cov qauv no khaws lub rooj dav dav thiab qhov tob, tab sis kho qhov ntev ntawm lub rooj zaum qhov siab thiab lub nraub qaum qhov siab raws li, thiab tshem tawm cov kev xav tau rau armrest qhov siab thiab qhov sib txawv ntawm qhov sib txawv.
3. Cov Khoom Siv Khoom Siv: (1) Cov khoom siv rau cov khoom siv sab nrauv yuav tsum ua raws li daim ntawv lo; (2) Cov khoom siv rau cov khoom siv sab hauv yuav tsum tsis muaj tawv tawv; (3) Cov ntsiab lus noo noo ntawm cov ntoo yuav tsum tsis pub tshaj qhov nruab nrab txhua xyoo qhov sib npaug ntawm cov dej noo ntawm cov ntoo hauv thaj av uas cov khoom nyob, yav dhau los tau teev tseg tias yog +1%. Daim Ntawv Ntxiv B (Normative Appendix) tau muab ntxiv rau tus qauv raws li lub hauv paus rau kev soj ntsuam cov khoom, qhia txog qhov sib npaug ntawm cov dej noo ntawm cov ntoo hauv ntau thaj tsam ntawm kuv lub teb chaws. (4) Qhov yuav tsum tau muaj ntau dua lossis sib npaug rau 4 qib rau cov xim qhuav kom nrawm nrawm tau ntxiv rau cov ntaub npuag, tawv, thiab tawv tawv.
4. Mechanical Performance Requirements: Cov kev ntsuam xyuas kev ua tau zoo hauv cov qauv no yog ua raws li kev sib koom ua ke ntawm cov kev xav tau ntawm lub rooj zaum thiab nraub qaum (tus qauv qub tau teev cov kev cai durability raws li lub rooj zaum elasticity hom), piv txwv li, durability yuav tsum dhau: Qib A 60,000 cycles; Qib B 40,000 cycles; thiab Qib C 20,000 cycles. Cov kev hloov pauv tau raug ua rau backrest looseness, armrest looseness, thiab compression.
5. Cov kev xav tau ntawm nplaim taws retardancy: xav txog kev txhim kho cov khoom lag luam thiab txo kev puas tsuaj rau tib neeg kev noj qab haus huv.
6. Kev Ntsuam Xyuas Kev Ntsuam Xyuas: Kev tshuaj xyuas cov khoom tau muab faib ua hom kev tshuaj xyuas thiab kev tshuaj xyuas lub Hoobkas. Kev soj ntsuam cov txiaj ntsig tau raug soj ntsuam raws li: Qib Siab Tshaj Plaws (Tsib Qib Siab), Qib Ib (Qib B), Qib Kawm Txuj Ci (Qib C), thiab Tsis Tsim Nyog.
