Maqolada benzinning hajmiy sarfini o‘lchash tizimini turli harorat va sarf rejimlarida laboratoriya sharoitida baholash metodikasi ishlab chiqiladi. Metodika o‘lchash vositalarini dastlabki tavsiflash, tajriba omillarini tanlash, o‘lchashlarni takrorlash, mahsulot hajmini tayanch sharoitga keltirish, natijalarni statistik qayta ishlash va o‘lchash noaniqligini baholash bosqichlarini qamrab oladi. Harorat va sarf rejimlari bo‘yicha tajriba matritsasini tuzish, o‘lchash ma’lumotlarini hujjatlashtirish va mustaqil tayanch qiymat bilan taqqoslash qoidalari bayon etiladi. Maqola tajriba metodikasiga bag‘ishlangan bo‘lib, amalda bajarilmagan o‘lchashlar uchun sonli natijalar keltirilmaydi. Taklif etilgan metodikani to‘liq amalga oshirish uchun benzin bilan ishlashga mos xavfsiz laboratoriya, aniqlangan turdagi sarf o‘lchagich va metrologik maqomi hujjatlashtirilgan taqqoslash vositasi talab etiladi.
