This document specifies a subjective image quality assessment methodology that covers a range from good quality up to mathematically lossless. Good quality, here, is defined as the visual quality level corresponding to a mean opinion score of 4 on a 5-point scale in a side-by-side comparison as in ITU-R BT.500. The threshold of visually lossless quality, as determined by an AIC-2 flicker test (ISO/IEC 29170-2), is included in the range covered by this document. For mathematically lossless compression, image quality assessment does not apply, but the methods described in this document can provide meaningful differentiation (in fractional JND units) between images that are visually lossless. The methodology targets specifically the assessment of distortions due to image coding (i.e., lossy compression) and not necessarily other kinds of distortions, e.g., capture, sensor or rendering artifacts.

This document specifies the physical performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and footwear should have the same minimum chemical protective barrier performance requirements as the fabric when an integral part of the clothing. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that other parts of ISO 16602 may well require testing according to test method standards which are not included in this standard. While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicates the intended use of the protective clothing. It is similarly important that the user (specifier) carries out a risk assessment in order to establish the correct protective performance levels for the intended task.

 

This document specifies a procedure for determining whether a perceptible sensory difference or similarity exists between samples of two products. The method is a forced-choice procedure. The method is applicable whether a difference exists in a single sensory attribute or in several attributes. The method is statistically less efficient than the triangle test (described in ISO 4120) but is easier to perform by the assessors. The method is applicable even when the nature of the difference is unknown (i.e. it determines neither the size nor the direction of difference between samples, nor is there any indication of the attribute(s) responsible for the difference). The method is applicable only if the products are fairly homogeneous. The method is effective for Two forms of the method are described:

 

This document specifies the chemical performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and footwear shall have the same minimum chemical (including solids, airborne particles, aerosols, liquids, and gases (including radioactive contaminants)) protective barrier requirements as the fabric when they are an integral part of the clothing. While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate the intended use of the protective clothing and that the user (specifier) carries out a risk assessment in order to establish the correct performance level for the intended task.

 

This document specifies minimum design and functional performance requirements for protective clothing against specified chemicals (including solids, airborne particles, aerosols, liquids, and gases (including radioactive contamination)) in the workplace and unidentified chemicals in emergency situations. These requirements cover all relevant parts of the ensemble which are attached/fitted to the chemical protective clothing, for example garment, visor, gloves, boots or bootees, ventilation (non-breathing), and other design features. This document does not specifically address protection against biological, thermal (flame, heat or cold), and ionizing radiation hazards as specific requirements are covered by other relevant standards. This type of equipment is not intended for immersion in liquids. The basic performance criteria for the components such as gloves, boots or respiratory protective equipment are given in other standards. Supplementary requirements are provided in this standard. Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have not been considered since protection against these additional hazards is beyond the scope of this standard.
