This document defines terms and definitions concerned in all standardization work within the scope of ISO/TC 300, i.e. terms used in the field of production and trade of solid recovered fuels that are prepared from non-hazardous waste. Terminology boundaries are described in Figure 1.

 

NOTE Solid biofuels are covered by the scope of ISO/TC 238.

Definitions in other standards with a scope different from the scope of this document can be different from the definitions in this document.

This document establishes the specifications relative to family C (gears) for lubricants, industrial oils and related products of Class L (see ISO 6743-6). This document deals only with lubricants for enclosed gear systems. Lubricants for open gears and greases for gears (enclosed or open) are not covered.

This document can be read in conjunction with ISO 6743-6. The following categories specified in ISO 6743-6 are covered by this document: CKB, CKC, CKD, CKE, CKSMP, CKTG, CKES, CKPG, CKPR.

This document provides requirements for operation of vehicles that use compressed natural gas (CNG) as a fuel, covering various aspects of NGV workshops including activities, risk management, planning, personnel, layout, systems and operations. It provides requirements regarding the management of NGVs including use, parking, fuelling, inspection, installation, repair and maintenance, disposal, transportation and documentation.

This document is applicable to the management of CNG vehicles with a fuel system pressure of 20 MPa (200 bar) at 15 °C. This document can also be applied to vehicles with higher fuel system pressures, taking into account additional safety aspects.

This document specifies several methods for the empirical estimation of the consistency of lubricating greases and petrolatum by measuring the penetration of a standardized cone.

The National Lubricating Grease Institute (NLGI) classifies greases according to their consistency, as measured by the 60 strokes worked penetration. The NLGI classification includes nine consistency numbers or grades, each grade corresponding to a given range of worked penetration. The NLGI classification is given in ISO 6743-99 [1] and ISO 12924 [2].

Clause 7 of this document specifies four procedures for determining the consistency of lubricating greases by measuring the penetration of a full-scale cone. These procedures cover the measurement of unworked, worked, prolonged worked and block penetrations. Penetrations up to 500 units can be measured.

Clause 8 of this document specifies methods for determining the consistency of lubricating greases when only small samples are available, by the use of cones a one-half-scale or one-quarter-scale of that used in Clause 7. The methods are applicable to greases having penetrations of 175 units to 385 units with the full-scale cone and are intended for use only if the size of the test sample prevents the use of cones described in Clause 7. They are not intended to replace the full-scale penetration as described in Clause 7, although a conversion to full-scale penetration is given in 10.2. See 8.1 for the limitations on the use of one-quarter-scale cones due to the poor precision.

NOTE 1 Unworked penetrations do not generally represent the consistency of greases in use as effectively as do worked penetrations. The latter are usually preferred for inspecting lubricating greases.

NOTE 2 Penetration of block greases can be obtained on those products that are sufficiently hard to hold their shape.

These greases generally have penetrations below 85 units.

Clause 9 of this document specifies a method for the determination of the consistency of petrolatum by measurement of the penetration of a full-scale cone, having penetrations up to 300 units. This method can also be used to estimate the consistency of slack waxes.
