CONTAINED IN VOL. 14.04, 2015 Defines designations, tolerances and dimensions for the ground surfaces of interchangeable taper-ground joints for industrial and laboratory equipment in full-length, medium-length, short-length and international-length grindings (ISO K-6 series) grindings.

1.1This 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 international-length (ISO K-6 series) grindings.

Note 1The 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 2Tolerances 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 3Although 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.

1.2The 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.
