ABSTRACT
This specification covers two types of metal ignition crucibles, nickel or platinum, complete with covers, for laboratory use. Two types of crucibles shall be classified according to their capacities: Type I is nickel with capacities of 100 mL and 250 mL and Type II is platinum with capacity of 20 mL. Type I are crucibles and covers which shall be made from 99.4% nickel, spun and hardened and Type II are crucibles and covers which shall be made from 99.9% platinum plus iridium, with the iridium content of not more than 0.4%. The crucibles shall have a standard shape with a flat base to give a firm and stable resting surface. The side wall shall form a sloping and convex surface extending up to the brim. Crucibles shall be of one-piece construction. Covers shall be flat, sunken in the center, and shall have an extension to serve as a handle. The sunken area in the center shall fit inside the crucible.

Standard Specification for Laboratory Glass Volumetric Apparatus

ABSTRACT
This specification covers general requirements for laboratory glass volumetric apparatus of Class A and B. The volumetric apparatus shall be manufactured from glass of suitable chemical and thermal properties, and shall be as free as possible from visible defects. Glasswares with a flat base shall stand firmly without rocking when placed on a level surface. For those requiring stoppers and stopcocks, glass stoppers shall be interchangeable while plastic stoppers used as alternative to glass ones shall be of inert plastic material. Stopcocks, on the other hand, shall permit smooth and precise control of outflow. Glasswares shall have clean, permanent graduation lines of uniform thickness confined to the cylindrical portions of their cross section, with the graduations lines being of Pattern I, II, or III and the unit of volume being cubic centimetre. Units of cubic decimeter or cubic millimetre may be used in special cases; however, only one unit of volume shall be used on the same piece of apparatus. Aside from graduation lines, the glassware shall bear inscriptions of the capacity, the temperature at which it is to be used, the method of use (whether to contain or to deliver), and for those that deliver though an outflow nozzle, the time required to empty the total nominal capacity with unrestricted outflow. Per service requirement, additional provisions may be specified as well.
SCOPE
1.1 This specification covers general requirements common to glass volumetric apparatus. Specific dimensions and tolerances for applicable instruments are given in other specifications as cited throughout this specification. Glass must conform to Specifications E438 and be calibrated in accordance with Practice E542.  
1.1.1 Class A—Each instrument shall be marked with the letter A to signify compliance with applicable construction and accuracy requirements. Instruments may be marked with an identification marker (serial number) at the option of the manufacturer.  
1.1.2 Class B—General purpose instruments are of the same basic design as Class A. However, volumetric tolerances for Class B instruments shall be within twice the specified range allowed for Class A unless otherwise specified.  
1.2 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.

Standard Specification for Laboratory Weights and Precision Mass Standards

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.
