Indicator Standards

This SAE Standard specifies symbols (i.e. conventional signs) for use on controls, indicators, and tell-tales applying to passenger cars, light and heavy commercial vehicles, and buses, to ensure identification and facilitate use. It also indicates the colors of possible optical tell-tales,...

This SAE Recommended Practice defines a method for implementing a bidirectional, serial communications link over the vehicle power supply line among modules containing microcomputers. This document defines those parameters of the serial link that relate primarily to hardware and software...

This SAE Recommended Practice shall cover mechanical-brake adjustment limit stroke indicators for actuators with visible exposed pushrods and electrical-brake adjustment limit stroke indicators for all air-brake actuators. This device shall indicate the foundation brake(s) may require...

These test methods cover the chemical analyses of hydraulic cements. Specific chemical test methods are grouped as reference test methods and alternative test methods. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic...

5.1 This test method is designed to determine the temperature at which the Wet Blue or Wet White specimen experiences shrinkage. In this test method, shrinkage occurs as a result of hydrothermal denaturation of the collagen protein molecules which make up the fiber structure of the Wet Blue or Wet...

5.1 The mean reflectance of the vitrinite maceral in sedimentary rocks as determined by this test method is used as an indicator of thermal maturity, that is, the progressive geochemical alteration of dispersed organic material experienced during diagenesis, catagenesis, and metagenesis. In...

This SAE Recommended Practice pertains to liquid level determination for any fluid compartment of off-road work machines as defined in SAE J1116 and ISO 6165.

1.1 This test method covers a procedure for determining the basic constituents in petroleum products in the field or laboratory using a pre-packaged test kit. The test uses a micro-titration resulting in a visual endpoint facilitated by a color indicator. 1.1.1 This test method covers base...

1.1 This test method covers the qualitative determination of the acidity of hydrocarbon liquids and their distillation residues. (Warning-Many hydrocarbon liquids are extremely flammable. Harmful if inhaled. Hydrocarbon liquid vapors can cause a flash fire.) 1.2 If desired to determine the basicity...

This specification covers airworthiness requirements for the design of powered fixed wing light sport aircraft, an "airplane." In order to comply with flight requirements, the following shall be evaluated: load distribution limit, propeller speed and pitch limit, stalling speed, takeoff, climb,...

4.1 The purpose of this standard practice is to provide the minimum requirements for the conduct of compliance audits. 4.2 The intended use of this practice is to provide a basis for an internal or external entity to develop an audit program. An audit program defines specific requirements for the...

This test method is for the determination of total sulfur in combustible fuel gases and is applicable to natural gases, manufactured gases, mixed gases, and other miscellaneous gaseous fuels. For the use of barium chloride titration following collection of sulfur dioxide by alternative procedures,...

4.1 The PCI is a numerical indicator that rates the surface condition of the pavement. The PCI provides a measure of the present condition of the pavement based on the distress observed on the surface of the pavement, which also indicates the structural integrity and surface operational...

This specification prescribes requirements for demonstrating that a building's location provides a minimal level of access to public transit that allows occupants to travel to places of employment and to run typical errands. It is intended to facilitate the decision-making process for selection of...

This specification establishes the requirements for the instrumentation aspects of airworthiness and design for "small" aircraft. It prescribes the Aircraft Type Code (ATC) compliance matrix based on airworthiness level, number of engines, type of engine(s), stall speed, cruise speed,...

This AS defines instruments which use inputs of static and pitot pressure equal to those which are utilized to establish the pressure altitude and speed of that aircraft. These pressures are applied to the instrument ports to provide means for generation of an aural warning whenever the aircraft...

4.1 Vickers and Knoop hardness tests have been found to be very useful for materials evaluation, quality control of manufacturing processes and research and development efforts. Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator...

1.1 This practice covers procedures for the preparation, standardization, and storage of the standard volumetric solutions and reagent testing solutions commonly used in chemical analysis. 1.2 The information in this practice is arranged as follows: Sections Referenced Documents 2 Terminology 3...

1.1 This practice covers the baseline and periodic performance evaluation of Digital Detector Array (DDA) systems used for industrial radiography. It is intended to ensure that the evaluation of image quality, as far as this is influenced by the DDA system, meets the needs of users, and their...
