1.1 This specification covers requirements for glass burets of precision and general-purpose grades suitable for laboratory use. 1.1.1 Class A—Each buret of precision grade may be marked with the letter “A” to signify compliance with applicable construction and accuracy requirements in Table 1 and Table 2. Each buret may be marked with a permanent serial number at the option of the manufacturer. 1.1.2 Class B—General purpose burets are of the same basic design as Class A burets. However, volumetric tolerances for Class B burets shall be within twice the specified range allowed for Class A burets. These burets need not be marked with their class designation or serial number. See Table 1 and Table 3 for tolerances and dimensional requirements. NOTE 1—The Twelfth General (International) Conference on Weights and Measures redefined the litre as a “special name for the cubic decimetre,” but agreed to permit continuance of the terms litre, millilitre, and mL, except in association with measurements of the highest precision. For volumetric glassware the difference between the old and new meanings of litre is negligible. Therefore, either mL or cm3 may be marked on ware covered by this standard. 1.1.3 Product with a stated capacity not listed in this standard may be specified Class A Tolerance when product conforms to the tolerance range of the next smaller volumetric standard product listed in Table 1.

1.1 This specification covers designations, dimensions, and tolerances for only the ground surfaces of interchangeable taper-ground joints for laboratory and industrial equipment in full-length, medium-length, short-length, and internationallength (ISO K-6 series) grindings. NOTE 1—The dimensions pertaining to full-length, medium-length, and short-length joints, other than for the tolerance on length of grind, were taken directly from the now obsolete Commercial Standard CS 21. NOTE 2—Tolerances on the diameters of the international-length joints do not agree with those given in ISO Recommendation R 383. These tolerances have been established to agree with those of CS 21 in order to prevent the negative projection (large end of inner joint being smaller than large end of outer joint) permitted by ISO. NOTE 3—Although glass is the most commonly used material for ground joints, other materials may be used as specified. Taper-ground joints constructed from glass should be of suitable chemical and thermal properties in accordance with Specification E438. Joints should be as free as possible of visible defects and conform to Specification E671. 1.2 The following precautionary caveat pertains only to the Test Method portion, Section 4, 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 and health practices and determine the applicability of regulatory limitations prior to use.

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. 1.2 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. 1.3 The burner described in this specification is suitable for use in the following ASTM standards: Specification C509, Test Method D229, Test Method D635, Test Method D876, Test Method D3014, Test Method D3801, Test Method D4804, Test Method D4986, and Test Method D5048. Safety hazards and known limitations on applicability of fire-test-response standards are addressed in the individual test methods. Note 1: This specification is equivalent to the ignition source specified in IEC 60695-11-3, Annex A and IEC 60695-11-4, Annex A. Note 2: This specification is equivalent to the P/PF2 ignition source specified in ISO 10093.

1.1 This specification covers two different types of disposable micropipets, calibrated “to contain,” used in measuring microlitre volumes of liquids. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 The following precautionary caveat pertains only to paragraph 9.1.1 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. 1.4 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.

1.1 This specification covers laboratory items for use until they are no longer considered functional for the intended purpose. It is written specifically for reusable items and is not to be confused with disposable (single use) items that are described in other standards. 1.2 This specification covers the sampling inspection and basic testing criteria for the following four types of laboratory glassware: blown and pressed glassware, nongraduated;2 blown and pressed glassware, graduated;2 tubular glassware, nongraduated; and tubular glassware, graduated. 1.3 This specification is intended to be used in conjunction with a standard specification for a specific laboratory glassware product. 1.4 The following precautionary statement pertains only to the test method portion, Section 6, 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. 1.5 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.
