Standards

This standard specifies legal metrology requirements for labelled packaged commodities with constant nominal content and subject to international trade.  It also covers sampling plans for net content verification of goods declared in units of mass or volume.

This standard specifies the requirements and methods of test for liquid household chorine bleaches.

This standard specifies requirements, including dimensions, materials, finish and selection for sampling for wire nails and cut nails. The following types of wire nails are covered by this standard: (a) Round plain head nails; (b) Round lost head nails; (c) Clout or slate nails; (d) Extra large head clout or felt nails; (e) Convex head roofing nails (chisel or diamond points); (f) Pipe nails (chisel point); (g) Panel pins; (h) Hardboard panel pins (round shank); (i) Hardboard panel pins (square shank); (j) Lath nails; (k) Plasterboard nails (jagged shank); (l) Oval brad head nails; (m) Oval lost head nails; (n) Tile pegs; (o) Tram nails with flat or raised head with chisel point; (p) Spring head twisted shank nails; (q) Square twisted shank flat head nails; (r) Washer head slab nails; (s) Dowels; (t) Annular ringed shank flat head nails; (u) Helical threaded shank flat head nails; and (v) Duplex head nails. The following types of cut nails are covered by this standard: (a) Cut clasp nails; and (b) Cut floor brads. The types of nail covered are illustrated in Tables 1 to 25 and in the corresponding diagrams, Figures 1 to 25.

This specification covers hollow and solid (see 5.3 and 5.4) concrete masonry units made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials. There are three classes of concrete masonry units: Normal Weight, Medium Weight, and Lightweight. These units are suitable for both load bearing and non-load bearing applications. This standard covers hollow blocks from sizes of 3in. (76.2mm) to 8 in. (203.2mm).

Concrete masonry units covered by this specification are made from lightweight or normal weight aggregates, or both.

This standard specifies performance requirements for hollow load-bearing concrete masonry units made from Portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) normal weight; (b) medium weight; and (c) lightweight.

This standard specifies requirements for hollow non-load-bearing concrete masonry units made from portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) Normal weight; (b) Medium weight; and (c) Light weight. It also covers the sampling and testing of hollow non-load-bearing concrete masonry units for compressive strength, absorption, weight, moisture content and dimensions. It does not cover blocks intended solely for decorative purposes.

These requirements cover ballasts of the resistance, reactance, and electronic (solid state) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, NEPA 70. A fluorescent lamp ballast may be determined by investigation to be acceptable for use, in a fixture or other device, with electric-discharge lamps of other than the fluorescent type. A product that contains features, characteristics, components, materials, or systems new or different from those in use when the standard was developed, and that involves a risk of fire, electric shocks, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally; anticipated by the intent of this standard.

These requirements cover portable, stationary, and fixed uninterruptible power supplies (UPS) rated 600 volts or less ac or dc that are intended for installation in accordance with the National Electrical Code, NFPA 70.  During intended operation, the UPS allows the utility to deliver ac and dc power to the connected load through either the power conversion portion of the UPS or a bypass source. The power conversion portion of the UPS consists of a rectifier and an inverter.  During periods of power fluctuations, or power outage, or both, the connected load receives ac and dc power from the battery supply and power conversion portion of the UPS.

This standard specifies the requirements and the methods of test for ice-cream and related products, with the incorporation of fruits, nuts, or chocolate either singly or in combination.
