Standards

This standard applies to varieties of grain of Cowpea Vigna unguiculata.

This standard specifies the quality requirements of all commercial cultivars of bananas obtained from the Musa spp., of the Musaceae family, in the green state and offered fresh to consumers, after they have been processed, packaged and conditioned.

This standard shall not apply to:

a)                  cooking bananas;

b)                 plantains;

c)                  bananas for industrial manufacturing.

This standard applies to commercial varieties of cassava grown from (Manihot dulcis baill and Manihot esculenta crantz) to be supplied fresh to the consumer, after preparation and packaging. Cassavas for industrial processing are excluded.

This standard applies to commercial varieties of cassava grown from (Manihot dulcis baill and Manihot esculenta crantz) to be supplied fresh to the consumer, after preparation and packaging. Cassavas for industrial processing are excluded.

This standard specifies the requirements of sweet peppers (Capsicum annuum L. var. grossum) which are to be supplied fresh to the consumer market at the export or import control stages, after preparation and packaging. The standard does not apply to sweet peppers for industrial processing.

This specification covers rigid PVC and CPVC compounds intended for general purpose use in extruded or molded form, including piping applications involving special chemical and acid resistance or heat resistance, composed of poly(vinyl chloride), chlorinated poly(vinyl chloride), or vinyl chloride copolymers containing at least 80 % vinyl chloride, and the necessary compounding ingredients. The compounding ingredients may consist of lubricants, stabilizers, non-poly(vinyl chloride) resin modifiers, pigments, and inorganic fillers. Note 1—Selection of specific compounds for particular end uses or applications requires consideration of other characteristics such as thermal properties, optical properties, weather resistance, etc. Specific requirements and test methods for these properties shall be by mutual agreement between the purchaser and the seller.

This specification covers joints for plastic pipe systems intended for drain, and gravity sewerage pipe at internal or external pressures less than 25-ft head using flexible watertight elastomeric seals. this specification is intended to cover test requirements, test methods, and acceptable materials. the test methods described for the joints are not intended to be routine quality control tests but to be reliability or performance requirements.

This test method describes two essentially equivalent procedures: one for obtaining a long-term hydrostatic strength category based on stress, referred to herein as the hydrostatic design basis (HDB); and the other for obtaining a long-term hydrostatic strength category based on pressure, referred to herein as the pressure design basis (PDB). The HDB is based on the material's long-term hydrostatic strength (LTHS),and the PDB is based on the product's long-term hydrostatic pressure-strength (LTHSP).

Adopted ASTM D 1598-02. This test method covers the determination of the time-to-failure of both thermoplastic and reinforced thermosetting/

resin pipe under constant internal pressure.
