根据利益相关方反馈的意见, 拟对AS/NZS 3500下水管道和排水设施 标准进行修订。修订意见将会与其修改前的原文一起呈现出来,这对澳大利亚标准而言尚属首次。
通过征求公众意见的评议期,每个文件的第一部分即修改后的文本将会出现在新出版的标准中。文件的第二部分是标准的现行版本,同时标出意见修改的部分。
“AS/NZS 3500是个庞杂的文件。我们希望,这种新的呈现方式可以鼓励更多群体发表意见。”委员会主席弗雷德.雷诺德(Fred Reynolds)先生如此解释。
《AS/NZS 3500》系列的以下更新部分现公开征求意见:
• 第一部分,用水服务
• 第二部分,清洁卫生的下水管道和排水设施
• 第四部分,热水供应
主要变动如下:
• 火灾防护隐患
• 对塑料管道及受阳光直射的设备要求
• 明确对非饮用水的要求
• 明确获准的连接方式
• 排水设施结构性塑料重衬的程序
• 对松散土壤中安装排水设施的要求
• 可循环热水系统的安装
• 恒温水龙头的使用(TMV 水龙头)
在去年对管道部门标准的复审之后,本次修订遵循的是严格依据结构、职能和时间框架制定的新的制定程序。
这些变化是由技术委员会WS-014下水管道和排水系统技术委员会及由业界技术专家组成的专家工小组完成的。
意见提交指示可于公众意见门户获悉。
公众意见提交截止日期为2017年12月7日星期四。
全部意见审阅完毕及委员会作出修订之后,定于2018年5月刊行,供《2019全国建筑规范》使用。
Seeking comments on revisions to AS/NZS 3500, Plumbing and Drainage
Following stakeholder feedback, proposed revisions to the AS/NZS 3500, Plumbing and
Drainage series will be presented with the changes tracked—a first for Standards Australia.
Through the public comment period, the first part of each document is the revised text as it
would appear in the new published standard. The second part of the document consists of
the current edition of the standard with proposed changes tracked.
"AS/NZS 3500 is a large, complex document. We hope this new method of presentation will
encourage more participation by the broader community in the commenting process," Chair
of the committee, Mr Fred Reynolds explained.
Updates to the following parts of the AS/NZS 3500 series are now open
for public comment:
• Part 1, Water services
• Part 2, Sanitary plumbing and drainage
• Part 4, Heated water services
The major changes include:
• Prevention backflow in fire services
• Requirements for plastic pipes and fittings installed in direct sunlight
• Clarification of certain requirements for non-drinking water services
• Clarification of permitted jointing methods
• Procedures for structural plastic re-lining of drains
• Requirements for installing drains in unstable soils
• Installation of circulatory heated water systems
• Use of thermostatically controlled taps (TMV Taps)
Following last year’s review of the plumbing sector, this revision followed the updated
development process with a strict adherence to structure, roles and time frames.
The changes were developed by the technical committee WS-014, Plumbing and
Drainage, and a series of specialist working groups comprised of technical experts from
across industry.
Instructions on how to submit a comment can be found through the Public Comment Portal.
The closing date for public comment is Thursday 7 December 2017.
Once all comments are reviewed and changes are made by the committee, publication is
targeted for May 2018 to allow adoption into the 2019 National Construction Code.
