GB 21551的本部分規定了家用和類似用途電器(以下簡稱“家用電器”)中使用的抗菌材料、零部件的抗菌及抗霉菌(以下簡稱“抗菌”)性能試驗方法和效果評價等。本部分適用于家用電器中使用的抗菌材料及相關抗菌零部件進行抗菌性能試驗的方法和效果評價。
本標準規定了食品毒理學檢測實驗室質量控制的管理要求、技術要求、過程控制要求和結果質量控制要求。本標準包括食品毒理學檢測實驗室從受理申請、樣品采集、樣品處理及樣品檢驗到出具檢驗報告、解釋結果及提出建議全過程的質量控制要求。本標準適用于食品毒理學檢測實驗室,亦可供其他毒理學檢測實驗室參考使用。
本標準規定了測量結果不確定度的四種評定方法。本標準適用于檢測實驗室的測量不確定度評定。
本標準規定了核電廠職業照射監測的一般要求、不同類別監測的技術要求及其監測結果評價和質量保證。本標準適用于為控制核電廠職業照射而進行的輻射監測。核電廠以外的其他核反應堆運行單位可參照使用。
本標準規定了衛生檢測與評價實驗室名詞術語的分類和定義(或含義)。本標準適用于衛生檢測與評價工作,特別是衛生檢測技術標準(規范)的編寫和實施。
本標準規定了用于檢測牡蠣閉合孢子蟲病的臨床診斷方法、組織印跡法、組織切片法、透射電鏡法、PCR方法和核酸原位雜交等方法。本標準適用于閉合孢子蟲病的流行病學調查、監測、診斷和出入境檢驗檢疫。
本標準規定了系統受控下基于質量控制和確認數據的測量不確定度評定。本標準適用于化學領域檢測實驗室的測量不確定度評定。
The present Part of the Standard specifies the identification and quantificationprocedures of the sampled PCDDs/PCDFs. It is an integral part of the complete measurement procedure. The use of the other two parts of this Standard, EN 1948-1:2003 and EN 1948-2:2003, describing sampling and extraction and clean-up, respectively, is necessary for the determination of the PCDDs/PCDFs. This Standard has been designed to measure PCDD/PCDF concentrations at about 0,1 ng I-TEQ/m cube in stationary source emissions.
This International Standard specifies a method that is applicable for the detection and enumeration of Cryptosporidium oocysts and Giardia cysts on or in food products that are described herein as fresh leafy green vegetables and berry fruits. With suitable controls, it may also be applicable for the examination of other fresh produce.
This document defines general terms which are help-ful for the communication within the aluminium indus-try and its customers relating to the chemical analysis.\nA glossary (Annex A) comprises all terms in alpha-betical order which are defined in this document.\nNOTE Most of the definitions are taken from or closely adapted to ISO standards and/or VIM.
IEC 62321, which is an International Standard, specifies the determination of the levels oflead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI)) contained in inorganicand organic compounds, and two types of brominated flame retardants, polybrominatedbiphenyls (PBB) and polybrominated diphenyl ethers (PBDE) contained in electrotechnicalproducts.This standard refers to the sample as the object to be processed and measured. The natureof the sample and the manner in which it is acquired is defined by the entity carrying out thetests and not by this standard.NOTE 1 Further guidance on obtaining representative samples from finished electronic products to be tested forlevels of regulated substances may be found in the future IEC Publicly Available Specification (PAS) for samplingdisjointment1.It is noted that the selection of the sample may affect the interpretation of the test results.This standard does not determine:? the definition of a “unit” or “homogenous material” as the sample;? the disassembly procedure employed for obtaining a sample;? assessment procedures.NOTE 2 Further guidance on assessment procedures may be found in the future IEC Technical SpecificationIEC/TS 62476
