Standards

This European has been prepared by Technical Committee CEN/TC 309 “Footwear”, the secretariat of which is held by AENOR. It shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2002, and conflicting national standards shall be drawn at the latest by May 2002.

This European Standard specifies a test method for assessing the tear strength of upper, linings and insocks or complete upper assembly, irrespective of t material, in order to assess the suitability for the end use.

This European Standard specifies a method for determining the flex resistance of outsoles. This method is intended to assess the effect of sole materials and surface patterns on cut growth. This method is applied to outsoles that, in accordance with the test mentioned in Clasuse6, have a maximum longitudinal rigidity of 30 N.

This Standard describes a test method for the determining of the resistance to separation of the upper from the outsole or to separate adjacent layers of the outsole or to cause tear failure of the upper or the sole is measures. It also defines conditions of aging that can be used for production control. It applies to all types of footwear (cementing, vulcanization, injection moulding, etc.) where the evaluation of sole adhesion on the upper is needed and where the upper is continuously assembles (closed shoe).

This European Standard specifies a method for the determination of abrasion resistance for outsole, irrespective of the material.

This document specifies three methods for determining the shape retention properties and compression strength of a doomed test specimen.

: This standard applies to the transport of petroleum and petroleum products by road tanker wagons licensed by the Guyana Energy Agency.

This standard applies to the transportation of petroleum and petroleum products by bulk transportation carriers licensed by the Guyana Energy Agency. This standard does not apply to road tanker wagons, marine transport and to the transportation liquid petroleum gases (LPG).

This standard specifies materials, construction, performance and testing requirements for low pressure single or two stage regulators for use with liquefied petroleum gas mixtures in vapour phase up to 4.903kN/m2 [50gf/cm2 or 500mm water column (WC)] outlet pressure.

1.1 This Guyana standard covers seven grades of diesel fuel oils suitable for various types of diesel engines. These grades are described as follows: 1.1.1 Grade No. 1-D S15—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 15 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S15 fuel. 1.1.2 Grade No. 1-D S500—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 500 ppm sulphur (maximum) and higher volatility than that provided by Grade No. 2-D S500 fuel.2 1.1.3 Grade No. 1-D S5000—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 5000 ppm sulphur (maximum) and higher volatility than that provided by Grade No. 2-D S5000 fuels. 1.1.4 Grade No. 2-D S15—A general purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 15 ppm sulphur (maximum). It is especially suitable for use in applications with conditions of varying speed and load. 1.1.5 Grade No. 2-D S500—A general-purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 500 ppm sulphur (maximum). It is especially suitable for use in applications with conditions of varying speed and load. 1.1.6 Grade No. 2-D S5000—A general-purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 5000 ppm sulphur (maximum), especially in conditions of varying speed and load. 1.1.7 Grade No. 4-D—A heavy distillate fuel, or a blend of distillate and residual oil, for use in low- and medium-speed diesel engines in applications involving predominantly constant speed and load.
