1.1 This test method enables an assessment of the fire spread characteristics of non-loadbearing exterior wall assemblies. 1.2 The test determines the comparative burning characteristics of exterior wall assemblies by evaluating the following: A Fire spread over the exterior surface; B Heat flow from the fire plume to the exterior surface; and C Fire spread within the test specimen. 1.3…

IEC 60335-2-110:2024 deals with the safety of microwave appliances intended for commercial use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. Appliances covered by this standard…

Scope This National Standard of Canada defines equipment requirements, performance criteria, and operating and testing procedures for the implementation of a vapour control system (VCS) in gasoline distribution networks including terminals, bulk plants, service stations and cargo tanks, commonly known as Stage I controls (see Figure 1 for a schematic representation). This standard does not…

IEC 61326-2-3:2020 specifies more detailed test configurations, operational conditions and performance criteria for transducers with integrated or remote signal conditioning. This document applies only to transducers characterized by their ability to transform, with the aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical signal, and to output the signal at…

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel. The method applies to the following…
