AS IEC 62217:2021 pdf free.Polymeric HV insulators for indoor and outdoor use – General definitions, test methods and acceptance criteria.
AS IEC 62217 is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard include both solid core and hollow insulators. They are intended for use on HV overhead lines and in indoor and outdoor equipment.
The object of this standard is
— to define the common terms used for polymeric insulators:
— to prescribe common test methods for design tests on polymeric insulators:
— to prescribe acceptance or failure criteria, if applicable:
These tests, criteria and recommendations are intended to ensure a satisfactory life-time under normal operating and environmental conditions (see Clause 5). This standard shall only be applied in conjunction with the relevant product standard.

AS ISO 37104:2020 pdf free.Sustainable cities and communities – Transforming our cities一Guidance for practical local implementation of AS IsO 37101. This document provides guidance on how to implement and maintain a management system for sustainable development based on ISO 37101 principles, specifically in the context of cities, but applicable to other forms of settlement. This document: — provides guidance for practical implementation ofa managernentsystem for sustainable development in cities and other settlements, based on ISO 37101; — establishes a methodological framework forthe systematic evaluation ofthe sustainable development schemes and achievements in the city or other settlements, based on the cross-analysis of the six purposes of sustainability and the 12 areas of action of ISO 37101; — illustrates how other International Standards can be used to support successful implementation of ISO 37101, including, in particular, ISO 37120 (which recommends a suite of city indicators mapped against the six purposes of ISO 37101) and ISO 37106 (which provides practical guidance on how to implement joined-up delivery and innovation across organizational boundaries within the city or settlement). This document is intended for organizing bodies, decision-makers, executive officers and managers in cities — usually, in the first instance, the relevant local governments. This document…
