Standard Specification for Laboratory Burner Used for Small-Scale Burning Tests on Plastic Materials

SCOPE
1.1 This specification covers the physical dimensions and characteristics of a laboratory burner to be used as an ignition source for small-scale burning tests on plastic materials. The burner is used with methane, propane or butane supply gases for flame heights of 20 to 125 mm.  Note 1-The burner described in this specification is suitable for use in the following ASTM standards: Specification C 509, Methods D229, Test Method D635, Methods D876, Test Method D3014, Method D3713, Method D3801, Test Method D4804, Test Method D4986, Test Method D5048, and Test Method F777. Safety hazards and known limitations on applicability of fire-test-response standards are addressed in the individual methods.
1.2 The values stated in SI units are to be regarded as the standard.  Note 2-This specification is referenced in ISO 10093. 20- and 125-mm test flames, calibrated in accordance with Practice D5207 are technically equivalent to ISO 10093 categories of ignition sources designated P/PF2 and P/PF3, respectively.

ABSTRACT
This specification covers laboratory weights and precision mass standards including their principal physical characteristics and metrological requirements. Maximum permissible error, magnetic property, density, and surface roughness for each weight shall be within the limits indicated in this specification. Physical characteristics shall be based on construction, design, surface area, materials, magnetism, density, surface finish, weight adjustment, and marking.
SCOPE
1.1 This specification covers weights and mass standards used in laboratories, specifically classes 000, 00, 0, 1, 2, 3, 4, 5, 6, and 7. This specification replaces National Bureau of Standards Circular 547, Section 1, which is out of print.  
1.2 This specification and calibration method is intended for use by weight manufacturers, national metrology institutes, weight calibration laboratories, accreditation bodies, users of weights, and regulatory bodies.  
1.3 This specification contains the principal physical characteristics and metrological requirements for weights that are used.  
1.3.1 For the verification of weighing instruments;  
1.3.2 For the calibration of weights of a lower class of accuracy; and  
1.3.3 With weighing instruments.  
1.4 Maximum Permissible Errors (formerly tolerances) and design restrictions for each class are described in order that both individual weights or sets of weights can be chosen for appropriate applications.  
1.5 Weight manufacturers must be able to provide evidence that all new weights comply with specifications in this standard (for example, material, density, magnetism, surface finish, mass values, uncertainties) to make any claim of compliance to Specification E617, Maximum Permissible Errors, weight classes, or metrological traceability.  
1.5.1 During subsequent calibrations, calibration laboratories must meet the requirements of ISO/IEC 17025:2017.  
1.5.2 Subsequent calibrations must meet all the requirements, including Sections 7, 8, and 9, Table 8 and Table 11 (environmental parameters) to make any claim of compliance to Specification E617, Maximum Permissible Errors, weight classes, or metrological traceability.
Note 1: Requirements set forth in NIST IR 6969 and NIST IR 5672 are compliant with all the requirements of Specification E617, Sections 7, 8, and 9.  
1.6 The values stated in SI units are to be regarded as standard.  
1.7 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.

ABSTRACT
This specification covers piston or plunger operated volumetric apparatus (POVA), in particular, the requirements, operating conditions, and test methods. POVA covered by this specification are pipettes, dispensers (with and without valve), dilutors, and displacement burets (with and without valve). Single measurement, replicate delivery, durability, functional (such as tests for leakage, broken parts, existence of air bubbles, and contamination), volumetric, and gravimetric tests shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers requirements, operating conditions, and test procedures for piston or plunger operated volumetric apparatus (POVA), as well as requirements for pipette operator training and qualification.  
1.2 This specification is applicable to all types of POVA. The following precautionary caveat pertains only to the test procedure portion, Annex A1 and Annex A2, of this specification: 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.  
1.3 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.

ASTM E596-22(Test Method)
Standard Test Method for Laboratory Measurement of Noise Reduction of Sound-Isolating Enclosures

SIGNIFICANCE AND USE
5.1 The noise reduction of an enclosure is a property of the enclosure, the location of the sound source used to measure noise reduction, and the space in which the enclosure is placed. It is not a property of the enclosure alone, and its measurement under different conditions can be expected to give different results. When the noise reduction is measured in accordance with this test method, the sound source is outside the enclosure and the sound field outside the enclosure approximates a diffuse sound field. Measurements made in accordance with this test method can be expected to be reproducible from one laboratory to another.  
5.2 The noise reduction measured in accordance with this test method may be used for the following purposes:  
5.2.1 To rank the order of sound-isolating enclosures according to noise isolation class, NIC.  
5.2.2 To estimate the highest one-third octave band sound pressure levels that can occur outside the enclosure without exceeding specified sound pressure levels inside the enclosure.  
5.2.3 To estimate the one-third octave band sound pressure levels that will occur inside the enclosure with specified sound pressure levels outside.  
5.3 The noise reduction measured in accordance with this test method may not estimate accurately the isolation that the enclosure will provide when it is used to isolate a noise source inside it from the space outside. The user should be cautious when using noise reductions measured by this test method to evaluate enclosures used to enclose noise sources.  
5.4 Sound-isolating enclosures are frequently made from prefabricated modular panels. The noise reduction measured by this test method applies to the complete enclosure and not to individual panels from which it is made and cannot be used to infer the sound transmission loss of the individual panels.  
5.5 Specifications for sound-isolating enclosures may include reference to noise reduction and noise isolation class measured in accordance with th...
SCOPE
1.1 This test method covers the reverberation room measurement of the noise reduction of sound-isolating enclosures.  
1.2 The noise isolation class may be determined from the noise reduction measured in accordance with this test method.  
1.3 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.  
1.4 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.
