ISO 7840 小型船舶 - 耐火燃油軟管-標(biāo)準(zhǔn)簡介

本國際標(biāo)準(zhǔn)規(guī)定了輸送汽油和柴油的耐火軟管的一般要求和物理試驗(yàn)，對(duì)于帶有永久安裝燃料系統(tǒng)的小型船只，對(duì)于帶有公稱孔徑在10毫米以下的軟管，設(shè)計(jì)工作壓力不超過0.34兆帕，對(duì)于帶有公稱孔徑在10毫米以下的軟管，設(shè)計(jì)工作壓力為0.25兆帕。?

This International Standard specifies general requirements and physical tests for fire- resistant hoses for conveying petrol or petrol blended with ethanol and diesel fuel or diesel fuel blended with FAME 10 mm and 0, 25 MPa for hoses up to 63 mm inner diameter in craft of hull length up to 24m including designed for a working pressure not exceeding 0, 34 MPa for hoses with nominal bore up to and It applies to hoses for small craft with permanently installed fuel systems. It does not apply to hoses entirely within the splash well at the stern of the craft connected directly to an outboard engine. Specifications for non-fire- resistant fuel hoses are given in IS0 84691. Specifications for permanently installed fuel systems are given in ISo 10088.
