ASTM E50-00 金属、矿物和相关材料的化学分析用仪器、试剂和安全措施的标准操作规程

1.1 These practices cover laboratory apparatus and reagents that are required for the chemical analysis of metals, ores and related materials by standard methods of ASTM. Detailed descriptions of recommended apparatus and detailed instructions for the preparation of standard solutions and certain nonstandardized reagents are included. An identifying number has been assigned each apparatus (see Section 8 ) and reagent (see Section 25) for convenience of reference in the analytical methods. Included also are general recommendations on the purity of reagents and protective measures for the use of hazardous reagents.1.2 The aim of these recommendations is to present descriptions of such apparatus and reagents as are common to several ASTM methods, and thus avoid needless repetition. No attempt has been made to provide a description of every apparatus and reagent prescribed in ASTM methods for the chemical analysis of metals. Other apparatus and reagents that are required will be found listed or specified in the individual methods of analysis.1.3 These recommendations are intended to apply to the ASTM methods of chemical analysis of metals when definite reference is made to these practices, as covered in Section 3.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Section 7 and Note 2.Note 2--The use of the verb "shall" (with its obligatory third person meaning) in this standard has been confined to those aspects of laboratory safety where regulatory requirements are known to exist. Such regulations, however, are beyond the scope of these practices.

ASTM E2056-00 多用途分析用合格分光仪和分光光度计使用代用混合物校准的标准实施规范

1.1 This practice relates to the multivariate calibration of spectrometers and spectrophotometers used in determining the physical and chemical characteristics of materials. A detailed description of general multivariate analysis is given in Practice E1655. This standard refers only to those instances where surrogate mixtures can be used to establish a suitable calibration matrix. This practice specifies calibration and qualification data set requirements for interlaboratory studies (ILSs), that is, round robins, of standard test methods employing surrogate calibration techniques that do not conform exactly to Practices E1655.Note 1--For some multivariate spectroscopic analyses, interferences and matrix effects are sufficiently small that it is possible to calibrate using mixtures that contain substantially fewer chemical components than the samples that will ultimately be analyzed. While these surrogate methods generally make use of the multivariate mathematics described in Practices E1655, they do not conform to procedures described therein, specifically with respect to the handling of outliers.1.2 This practice specifies how the ILS data is treated to establish spectrometer/spectrophotometer performance qualification requirements to be incorporated into standard test methods.Note 2--Spectrometer/spectrophotometer qualification procedures are intended to allow the user to determine if the performance of a specific spectrometer/spectrophotometer is adequate to conduct the analysis so as to obtain results consistent with the published test method precision.1.2.1 The spectroscopies used in the surrogate test methods would include but not be limited to mid- and near-infrared, ultraviolet/visible, fluorescence and Raman spectroscopies.1.2.2 The surrogate calibrations covered in this practice are: multilinear regression (MLR), principal components regression (PCR) or partial least squares (PLS) mathematics. These calibration procedures are described in detail in Practices E1655.1.3 For surrogate test methods, this practice recommends limitations that should be placed on calibration options that are allowed in the test method. Specifically, this practice recommends that the test method developer demonstrate that all calibrations that are allowed in the test method produce statistically indistinguishable results.1.4 For surrogate test methods that reference spectrometer/spectrophotometer performance practices, such as Practices E275, E387, E388, E579, E925, E932, E958, E1421, E1683, E1866 or E1944, this practice recommends that instrument performance data be collected as part of the ILS to establish the relationship between spectrometer/spectrophotometer performance and test method precision.

BS DD 246:1999 锥形色度计的使用推荐规范

This Draft for Development examines the limitations of the cone calorimeter as currently used for building products and recommends ways in which some of these may be overcome for other types of products for other application areas.It draws together information from a large body of experience with regard to the use of the instrument into a set of guidelines which will help to standardize the use of the cone calorimeter in this wider scope. Particular guidance is given on aspects of specimen preparation and on the behaviour, such as melting, spalling and intumescing, of specimens exposed to radiant heat. The relevance of specimen thickness and the use of substrate and methods of fixing to substrate is also discussed. Advice is given on approaches to testing a variety of "non-standard" products. Recommendations are made on techniques of calibration of the apparatus, selection of appropriate heat flux levels and ignition protocols.

This European Standard specifies general requirements for the construction and testing of apparatus for the detection and measuring of combustible or toxic gases or vapours in ambient air by measuring the spectral absorption by the gases or vapours over extended optical paths, ranging typically from one metre to a few kilometres. Such apparatus measures the integral concentration of the absorbing gas over the optical path in units such as LEL metre for combustible gases and ppm metre for toxic gases. NOTE 1 Actual values of concentration can only be deduced where it can be established that the concentration is uniform over the optical path, as for example in very short optical paths (

BS IEC 61832:1999 分析仪系统.技术询价和报价评估指南

This report is intended as a guide to assist in the development of a specification for analysers and their associated support systems for enquiry purposes and the subsequent assessment of the bids presented by the prospective vendors. This report is not intended as a design specification in its own right and design guidance has been deliberately omitted. It should be read in conjunction with other standards calling up examples of design detail, e.g. NAMUR, EEMUA, ISA. The technical report IEC/TR 61831, also being published, will supplement design guidance. To simplify the specification and bid process it is desirable to have a recommended procedure for both the enquiry documentation and the response from the analyser vendor. This document is intended to provide such a framework.
