APPENDIX A - DEFINITIONS FOR QUALITY SYSTEMS FROM NELAC 

The following selected definitions are from published texts in the 2003 NELAC Standard, June 5, 2003. 

Acceptance Criteria: specified limits placed on characteristics of an item, process, or service defined in 

requirement documents. (ASQC) 

Accuracy: the degree of agreement between an observed value and an accepted reference value. Accuracy 

includes a combination of random error (precision) and systematic error (bias) components which are due to 

sampling and analytical operations; a data quality indicator. (QAMS) 

Analyst: the designated individual who performs the "hands-on" analytical methods and associated techniques 

and who is the one responsible for applying required laboratory practices and other pertinent quality controls to 

meet the required level of quality. (NELAC) 

Assessment: the evaluation process used to measure or establish the performance, effectiveness, and conformance 

of an organization and/or its systems to defined criteria (to the standards and requirements of NELAC). (NELAC) 

Assessment Criteria: the measures established by NELAC and applied in establishing the extent to which an 

applicant is in conformance with NELAC requirements. (NELAC) 

Assessment Team: the group of people authorized to perform the on-site inspection and proficiency testing data 

evaluation required to establish whether an applicant meets the criteria for NELAP accreditation. (NELAC) 

Assessor: one who performs on-site assessments of accrediting authorities and laboratories’ capability and 

capacity for meeting NELAC requirements by examining the records and other physical evidence for each one of 

the tests for which accreditation has been requested. (NELAC) 

Audit: a systematic evaluation to determine the conformance to quantitative and qualitative specifications of 

some operational function or activity. (EPA-QAD) 

Batch: environmental samples that are prepared and/or analyzed together with the same process and personnel, 

using the same lot(s) of reagents. A preparation batch is composed of one to 20 environmental samples of the 

same NELAC-defined matrix, meeting the above mentioned criteria and with a maximum time between the start 

of processing of the first and last sample in the batch to be 24 hours. An analytical batch is composed of 

prepared environmental samples (extracts, digestates or concentrates) which are analyzed together as a group. An 

analytical batch can include prepared samples originating from various environmental matrices and can exceed 20 

samples. (NELAC Quality Systems Committee) 

Blank: a sample that has not been exposed to the analyzed sample stream in order to monitor contamination 

during sampling, transport, storage or analysis. The blank is subjected to the usual analytical and measurement 

process to establish a zero baseline or background value and is sometimes used to adjust or correct routine 

analytical results. Blanks include: 

• Equipment Blank: a sample of analyte-free media which has been used to rinse common sampling equipment 

to check effectiveness of decontamination procedures. (NELAC) 

• Field Blank: blank prepared in the field by filling a clean container with pure de-ionized water and 

appropriate preservative, if any, for the specific sampling activity being undertaken. (EPA OSWER) 

• Instrument Blank: a clean sample (e.g., distilled water) processed through the instrumental steps of the 

measurement process; used to determine instrument contamination. (EPA-QAD)

issued by a certifying body. (ISO Guide 30 - 2.2) 

Chain of Custody Form: record that documents the possession of the samples from the time of collection to 

receipt in the laboratory. This record generally includes: the number and types of containers; the mode of 

collection; collector; time of collection; preservation; and requested analyses. 

(NELAC) 

Confidential Business Information (CBI): information that an organization designates as having the potential of 

providing a competitor with inappropriate insight into its management, operation or products. NELAC and its 

representatives agree to safeguard identified CBI and to maintain all information identified as such in full 

confidentiality.

Spike: a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery 

efficiency or for other quality control purposes. (NELAC) 

Standard: the document describing the elements of laboratory accreditation that has been developed and 

established within the consensus principles of NELAC and meets the approval requirements of NELAC 

procedures and policies. (ASQC)

Standard Operating Procedures (SOPs): a written document which details the method of an operation, analysis 

or action whose techniques and procedures are thoroughly prescribed and which is accepted as the method for 

performing certain routine or repetitive tasks. (QAMS) 

Standard Method: a test method issued by an organization generally recognized as competent to do so. 

Standardized Reference Material (SRM): a certified reference material produced by the U.S. National Institute 

of Standards and Technology or other equivalent organization and characterized for absolute content, independent 

of analytical method. (EPA-QAD) 

Statistical Minimum Significant Difference (SMSD): the minimum difference between the control and a test 

concentration that is statistically significant; a measure of test sensitivity or power. The power of a test depends in 

part on the number of replicates per concentration, the significance level selected, e.g., 0.05, and the type of 

statistical analysis. If the variability remains constant, the sensitivity of the test increases as the number of 

replicates is increased. (NELAC) 

Supervisor (however named): the individual(s) designated as being responsible for a particular area or category 

of scientific analysis. This responsibility includes direct day-to-day supervision of technical employees, supply 

and instrument adequacy and upkeep, quality assurance/quality control duties and ascertaining that technical 

employees have the required balance of education, training and experience to perform the required analyses. 

(NELAC) 

Surrogate: a substance with properties that mimic the analyte of interest. It is unlikely to be found in 

environment samples and is added to them for quality control purposes. (QAMS) 

Suspension: temporary removal of a laboratory’s accreditation for a defined period of time, which shall not 

exceed six months, to allow the laboratory time to correct deficiencies or area of non-compliance with the 

NELAC standards. (NELAC) 

Technical Director: individual(s) who has overall responsibility for the technical operation of the environmental 

testing laboratory. (NELAC) 

Technology: a specific arrangement of analytical instruments, detection systems, and/or preparation techniques. 

Test: a technical operation that consists of the determination of one or more characteristics or performance of a 

given product, material, equipment, organism, physical phenomenon, process or service according to a specified 

procedure. The result of a test is normally recorded in a document sometimes called a test report or a test 

certificate. (ISO/IEC Guide 2-12.1, amended) 

Test Method: an adoption of a scientific technique for a specific measurement problem, as documented in a 

laboratory SOP or published by a recognized authority. (NELAC) 

Test Sensitivity/Power: the minimum significant difference (MSD) between the control and test concentration 

that is statistically significant. It is dependent on the number of replicates per concentration, the selected 

significance level, and the type of statistical analysis (see Chapter 5, Appendix D, section 2.4.a). (NELAC) 

Tolerance Chart: A chart in which the plotted quality control data is assessed via a tolerance level (e.g. ± 10% of 

a mean) based on the precision level judged acceptable to meet overall quality/data use requirements instead of 

statistical acceptance criteria (e.g. ± 3 sigma) (applies to radio bioassay laboratories). (ANSI) 

Traceability: the property of a result of a measurement whereby it can be related to appropriate standards, 

generally international or national standards, through an unbroken chain of comparisons. (VIM-6.12)

United States Environmental Protection Agency (EPA): the federal governmental agency with responsibility 

for protecting public health and safeguarding and improving the natural environment (i.e., the air, water, and land) 

upon which human life depends. (US-EPA) 

Validation: the confirmation by examination and provision of objective evidence that the particular requirements 

for a specific intended use are fulfilled. 

Verification: confirmation by examination and provision of evidence that specified requirements have been met. 

(NELAC) 

NOTE: In connection with the management of measuring equipment, verification provides a means for 

checking that the deviations between values indicated by a measuring instrument and corresponding 

known values of a measured quantity are consistently smaller than the maximum allowable error defined 

in a standard, regulation or specification peculiar to the management of the measuring equipment. 

The result of verification leads to a decision either to restore in service, to perform adjustment, to repair, 

to downgrade, or to declare obsolete. In all cases, it is required that a written trace of the verification 

performed shall be kept on the measuring instrument’s individual record. 

Work Cell: a well-defined group of analysts that together perform the method analysis. The members of the 

group and their specific functions within the work cell must be fully documented. 

(NELAC) 

Working Range: the difference between the Limit of Quantitation and the upper limit of measurement system 

calibration.
