Product Code:SAE J1792/1
Title:Self-Propelled Sweepers--Air Flow Performance--Part 1: Suction Air Volume Performance
Issuing Committee:Mtc2, Sweeper, Cleaner, And Machinery
Scope:This SAE Standard establishes a test method and a definition for disclosing the suction air volume performance of self-propelled sweepers that solely use a pneumatic conveyance means for the collection and transfer of "sweepings" into a collection hopper.The purpose of the document describes a test practice for measuring the suction air movement occurring in vacuum and regenerative air street sweepers described in SAE J2130. The document also proposes a format for the presentation of the results. The document can be used to disclose or compare particular operating performance criteria under similar conditions.【英文标准名称】:Determinationoffatcontentofmilkandmilkproducts(Gerbermethod)-Methods
