ASTM E2335-22 实验室监视器标准指南

1.1 This guide provides a general outline, for use by a laboratory monitor, to assess the qualifications of a laboratory that has requested to participate in a specific ASTM interlaboratory test. 1.2 The preliminary assessment is based on observations made before initiation of any interlaboratory tests. 1.3 The subcommittee, which appoints the laboratory monitor, specifies the minimum requirements that an organization should meet to qualify as a participant for the interlaboratory test. If a laboratory qualification test (pretest) is to be included, see details in Section 13. 1.4 This fire standard can not be used to provide quantitative measures. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1 This guide is under the jurisdiction of ASTM Committee E05 on Fire Standards and is the direct responsibility of Subcommittee E05.31 on Terminology and Services / Functions.

ASTM E95-68(2022) 通风速率可控的单元式烤箱标准规范

1.1 This specification covers the general requirements of a cell-type oven with controlled rates of ventilation for determining loss in weight or changes in properties of materials on heating at elevated temperatures. These specifications take into account the fact that chamber geometry, rate of ventilation, and temperature each affect the rate of loss of volatile constituents from a material, or the rate of change in other properties. This oven is recommended whenever the results are dependent on the time and temperature of heating, the amount of ventilation, or both. It is assumed that specific requirements such as specimen shape and dimensions, rate of ventilation, time, and temperature will be included in the applicable material specifications or test methods. NOTE 1—Ovens meeting these specifications have been found useful for determination of plasticizer loss in plastics, and for controlled aging of elastomers and plastics. 1.2 The values stated in inch-pound units are to be regarded as the standard. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
