Title:Access Systems for Off-Road Machines
Issuing Committee:Hftc1, Controls, Visibility, Anthropometrics, Accessiblty
Scope: Minimum criteria are provided for steps, stairways, ladders, walkways, platforms, handrails, handholds, guardrails, and entrance openings which permit ingress to and egress from operator, inspection, maintenance or service platforms on off-road work machines parked in accordance with the manufacturer's instructions.This SAE Recommended Practice pertains to off-road self-propelled work machines used in construction, general purpose industrial, agricultural (agricultural tractors only), forestry and specialized mining machinery categories as defined in SAE J1116 JUN86. It also pertains to specialized off-road machines used in mining such as shovels, draglines, and drills not identified in SAE J1116 JUN86.The minimum criteria established herein is based on one unladen person using the access system at any one time.

本标准适用于测定能在甲苯和异丙醇混合溶剂中全溶或几乎全溶的石石油产品和润滑剂酸性或碱性组分，它适用于测定在水中离解常数大于10的-9次方的极弱酸或碱不影响测定，如果盐类水解常数大于10的-9次方，则有影响。本标准可用于表明使用中的油品在氧化条件下的相对变化。尽管滴定是在规定条件下进行的，但是本标准不能测定绝对酸性和碱性，以预测油品在使用条件下的性能。已经知道酸值或碱值与轴承腐蚀之间没有必然联系。
