Sound Standards

The scope of this Procedural Guide includes the basic elements that are required to conduct and report the results of Sound and Vibration Testing for building HVAC systems. PURPOSE This guide is intended for trained Sound and Vibration (S&V) Supervisors and Technicians to assure that...

FOREWORD This first edition of HVAC Sound and Vibration was developed to provide in−depth, HVAC−specific guidance in the art of sound and vibration measurement and mitigation. In addition to this manual a chapter on the subject is provided in HVAC Systems Duct Design. Also, in HVAC...

This SAE Recommended Practice establishes the test procedure, environment, and instrumentation to be used for measuring the exterior exhaust sound level for passenger cars, multipurpose vehicles, and light trucks under stationary conditions providing a continuous measure of exhaust system or...

This SAE Standard presents a test procedure for determining the airborne sound insulation performance of materials and composite layers of materials commonly found in mobility, industrial, and commercial products under conditions of representative size and sound incidence so as to...

This specification covers cast sound-signalling bells, together with bulkhead mounting plates for the smaller bells, for use on ships, boats, and other marine craft, for compliance with the rules in the convention on the International Regulations for Preventing Collisions at Sea. Bell...

This specification covers gongs for use on ships of certain length, as required by International Regulations. The gong cylinder, brackets, clapper rod, "U" bracket, washers, and clapper support pin shall be made of stainless steel. The clapper mass shall be made of cast alloy steel. In addition,...

5.1 Measurement of the sound absorption of a room is part of the procedure for other acoustical measurements, such as determining the sound power level of a noise source or the sound transmission loss of a partition. It is also used in certain calculations such as predicting...

1 Scope and object This International Standard is a design qualification standard applicable to solar trackers for photovoltaic systems, but may be used for trackers in other solar applications. The standard defines test procedures for both key components and for the complete tracker system. In...

1.1 This specification covers the minimum requirements for and methods of application of exterior gypsum panel products that are specifically designed for use as a substrate for exterior cladding. 1.1.1 This specification does not cover gypsum panel products that are specifically designed for...

This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-chromium-iron-titanium alloys with Copper Alloy UNS No. C18080. The material for manufacture shall be a cast bar, cake, slab or so forth of such purity and soundness as to be suitable for...

This specification covers high magnesium marine application aluminum-alloy in those alloy tempers for flat sheet, coiled sheet, and plate, in the mill finish that are intended for marine and similar environments. An inspection lot shall consist of an identifiable quantity of material of the same...

6.1 A primary use intended for this practice is for qualifying ASTM International Standards as Standard Test Methods. In the past, a "Precision and Bias" report has been required. However, recently a statement of uncertainty has become an acceptable alternative to Guide D3670. Inclusion of such a...

1.1 This Standard covers requirements as related to the following: a) Discrete electrical control units and accessories for fire alarm systems including smoke control, releasing, Building System Information Unit (BSIU), and emergency communication systems; b) Electrically- and...

1.1 These practices cover procedures for measuring one-, two-, or three-dimensional vector wind components and sonic temperature by means of commercially available sonic anemometer/thermometers that employ the inverse time measurement technique. These practices apply to the measurement of wind...

1.1 This test method provides guidance to the methodology used in the measurement of building interior sound levels. 1.2 This test method describes procedures for measuring sound in enclosed residential spaces produced by built-in utilities and major appliances such as plumbing,...

1.1 This practice describes procedures for making joints suitable for pressure service with polyethylene (PE) pipe and fittings by means of electrofusion joining techniques in, but not limited to, a field environment. Other suitable electrofusion joining procedures are available from various...

This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities. Fine aggregate...
