Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Resin chemistry includes the following:

process of curing/cross linking of resins

rate of cure and change of properties over cure time

changes in viscosity and other flow properties during progress of cure

final properties of resin post-cure

Environmental changes include one (1) or more of the following:

temperature

humidity

air flow/wind

solar/ultraviolet (UV) insolation

Resin composition includes the following:

resin/catalyst ratio

resin/promoter ratio

resin/catalyst/promoter ratios

changing temperature of resin components (e.g. using chilled catalyst or resin)

ratios of other resin system components

Most appropriate resin composition changes include one (1) or more of the following:

comply with product requirements

adjust for the current conditions

have greatest ease of use in manufacture

have best financial return

have greatest sustainability contribution

Alternative process changes include one (1) or more of the following:

controlling the environmental conditions

moving the timing of the job to when conditions are more favourable (e.g. at night)

moving the location of the job to where conditions are more favourable (e.g. in plant, different site and in shade)

Conditions that can be adjusted to improve outcomes include the following:

unusually hot/cold workplace/weather

extreme humidity

very tight/unusual specification of properties required of product

high/low air flow/wind

Sustainability includes the following:

survival of the ecology/physical environment

economic viability

social sustainability
