(Instead of the removable sticker consider a tag for evacuated tubes.)12SANS 1307:2009Edition 46.3 Instruction bookletA booklet or leaflet in English shall be attached to each solar water heater and shall set out the following:a) information regarding the thermal properties of the solar water heater (see SANS 6211- 1 andSANS 6211-2);b) instructions for the safe and correct installation of the complete solar water heater, with adescription of all operating components and instructions for regular maintenance, including, when relevant, the maintenance of any sacrificial anode;c) clear and unambiguous advice regarding resistance to freezing and hail (see 6.1(f));d) safety precautions; ande) precautions regarding corrosion prevention and warning details are given in annex B.The information contained on the marking label shall be included in the booklet (see 6.1 and SANS 151).13SANS 1307:2009 Edition 414Annex A(normative) Notes to purchasersThe following requirements shall be specified in tender invitations and in each order or contract:a) the type of solar water heater (see 4.1);b) the type of heating system (see 4.2);c) the type of operating system (see 4.3);d) whether the collector is to be designed to operate with or without a cover (see 4.5);e) the working pressure (see 4.10) for both primary and secondary circuits;f) whether the solar heater is hail resistant (see 4.11.2); andg) whether it has a supplementary energy source or not (see 4.2).Annex B(informative)Factors governing corrosion and internal scalingof solar water heating systems1)B.1The tendency for metal corrosion or scaling to occur in a solar water heating system will depend on the characteristics of the water in the system. The evaluation given in annexes B.2 to B.4 may be included to aid in developing an acceptable corrosion prevention procedure.B.2 A full water analysis should be carried out and the Langelier Saturation Index and the Ryznar Stability Index calculated to give a guide as to the expected scaling/corrosion tendency of the water.B.3 The known performance of metals in a particular water should be ascertained from local user and supplier experience and checked against the likely performance as predicted from chemical analysis of the water. It should always be remembered, however, that design factors (open circuit, closed circuit, material choice, crevices, etc.) may override factors predicted from water chemistry or from the corrosion history.B.4In water with a high chloride or a high sulphate content, predictions calculated from a chemical analysis of the water should be treated with caution. It is difficult to define what a high chloride content is since this could vary from water to water and from metal to metal. The hardness of the water could be an important factor in terms of the chloride tolerance of a metal (see annex C).1) Callaghan, B G. Corrosion of solar water heating systems. British Corrosion Journal, Vol. 14, No. 2, 1979, p. 78.SANS 1307:2009Edition 415Annex C(informative)Chloride content of water supplied to certain South African urban areasIt should be emphasized that the figures given in table C.1 should not be regarded as representative of the water generally supplied to cities and towns.

The cold inlet to the solar pre-heater is connected downstream of the existing pressure control valve, and the hot outlet of the solar pre-heater is connected to the inlet connection of the existing electrical storage water heater, not into its hot outlet pipe. Flow of solar heated water to the pre-existing electrical water heater only occurs when hot water is drawn off at terminal fittings. This option may negatively affect flow pressure performance at terminal fittings due to the additional in-line friction pressure losses.b) A solar circulating retrofit option or any appropriate system in table 1 may be used. Thecirculating potable water between the solar water heater and the existing storage water heater must be connected so that the heated water is circulated between the retrofitted solar water heater and the existing electrical storage water heater.D.5 I n both the (a) and (b) options the hot water supply or circulating pipes from the solar water heater may not be connected to the hot outlet pipe of the existing electrical storage water heater. The pressure rating of the solar water heating system shall be matched to that of the existing electrical storage water heater.Annex E(informative)Quality verification of solar water heatersWhen a purchaser requires ongoing verification of the quality of solar water heaters, it is suggested that instead of concentrating solely on evaluation of the final product, he also direct his attention to the manufacturer's quality system. In this connection it should be noted that SANS 9001 covers the provision of an integrated quality system.。

中国R o H S拟“扩物质”,4种邻苯类有害物质须关注

2022/4准与认证40标STANDARD & CERTIFICATION标准修订先行目前,中国RoHS 有害物质包括铅及其化合物、汞及其化合物、镉及其化合物、六价铬化合物、多溴联苯(PBB)、多溴二苯醚(PBDE)以及国家规定的其他有害物质。

对于纳入《电器电子产品有害物质限制使用达标管理目录(第一批)》(以下简称《达标管理目录》)的12类产品,铅、汞、锅、六价铬、多溴联苯和多溴二苯醚的含量应该符合电器电子产品有害物质限制使用限量要求等相关标准,并纳入电器电子产品有害物质限制使用合格评定制度管理范围。

标准作为中国RoHS 制度的技术支撑文件,主要指向GB/T 26572-2011《电子电气产品中限用物在不远的将来,4种邻苯类有害物质或将纳入中国电器电子产品有害物质限制使用管理。

2022年3月14日,工业和信息化部电器电子产品污染防治标准工作组(以下简称标准工作组)以视频会议的形式组织召开了深化电器电子产品有害物质限制使用管理工作启动会。

这次会议不仅分析了当前电器电子领域有害物质限制使用的国内外行业执行情况,更明确传递出一个信息——中国RoHS 的管控物质将扩容,拟将4类邻苯二甲酸酯类物质(包含DEHP、BBP、DBP、DIBP)纳入《电器电子产品有害物质限制使用管理办法》(以下简称《管理办法》)有害物质清单。

本刊记者 于璇中国R o H S 拟“扩物质”,4种邻苯类有害物质须关注41质的限量要求》、GB/T 26125《电子电气产品六种限用物质(铅、汞、镉、六价铬、多溴联苯和多溴二苯醚)的测定》等。

中国RoHS“扩物质”的第一步,正是对GB/T 26572-2011《电子电气产品中限用物质的限量要求》进行修订,新增4种邻苯类有害物质的限量要求。

根据标准工作组的技术,这次标准修订工作预计于2022年9月底完成。

在完成标准修订后,中国RoHS此次“扩物质”将进入“政策文件发布及修订”阶段。

《电器》记者从会上获悉,新增4种邻苯类有害物质政策文件或将以部文或部公告的形式发布,并将向WTO/TBT 通报,计划的实施过渡期为180天。

各国安规认证大全(带图标)讲解

现在世界各国各种安规标准大约有几十种,但是都大同小异。

我们在日常工作中经常使用的有:IEC——CB、EN——CE(GS)、UL、GB——3C。

所有这些标准,如果从他们的相似性。

大约可以分为2大类:1、由IEC标准延伸出来的EN、GB等。

2、有UL延伸出来的标准。

IEC标准/EN标准:IEC/EN 60335-1 (家用和类似用途电器的通用标准)IEC 60335-2-15(液体加热器标准)IEC 60335-2-13(油炸锅、电煎锅标准)IEC 60335-2-3 (电熨斗标准)IEC 60335-2-85 (蒸汽熨衣器标准)UL标准:UL 1026 (家用电烹饪及食物加工器具)UL1083 (家用电长柄平底锅和煎炸型器具)UL 1082 (家用电咖啡壶及酿造类器具)UL 1005 (家用电熨斗器具)GB标准:GB 4706.1 (家用和类似用途电器的通用标准)GB 4706.2(电熨斗标准)GB 4706.19 (液体加热器标准)GB 4706.56 (油炸锅、电煎锅标准现在世界各国的认证可以分为以下几种:1、CB体系:CB体系是“Certification Bodies‘Scheme”(认证机构体系)的缩写,CB体系是电工产品安全测试报告互认的第一个真正的国际体系。

各个国家的国家认证机构(NCB)之间形成多边协议,制造商可以凭借一个NCB颁发的CB测试证书获得CB体系的其他成员国的国家认证。

CB体系的主要目标是促进国际贸易,其手段是通过推动国家标准与国际标准的统一协调以及产品认证机构的合作,而使制造商更接近于理想的“一次测试,多处适用”的目标。

目前,CB体系开展了十四大类的电工产品的测试,测试结果在43个成员国之间是相互认可的,同时,也被很多未参加CB体系的国家所承认。

IECEE-CB体系目前的成员国是:阿根廷、奥地利、澳大利亚、白俄罗斯、比利时、巴西、加拿大、中国、捷克、德国、丹麦、西班牙、芬兰、法国、英国、希腊、匈牙利、印度、爱尔兰、以色列、意大利、日本、韩国、墨西哥、荷兰、新西兰、挪威、波兰、葡萄牙、俄罗斯、罗马尼亚、新加坡、斯洛伐克、斯洛文尼亚、南非、土耳其、乌克兰、美国、南斯拉夫、瑞士、马来西亚、瑞典、泰国。

SANS10140-3南非标准

This edition cancels and replaces the first revision (SABS 0140-3:1992).
Introduction
In a multilingual country such as South Africa, it makes good sense to try to arrive at a common “language” to serve both as an identification of the contents of specific pipelines and as a warning. This “language” usually appears on the pipe in the form of a pipeline colour coding system or a written identification of the contents (descriptive code indicator) or, where possible, both.
– It is imperative that those who carry out work involving, or in the vicinity of, a group of pipelines be trained to understand the colour coding system from induction training to ongoing training and toolbox discussions. Identifying and assisting any colour-blind workers are also important facets of this training.

在南非,这指的是职业健康安全法案1993(法案号85,1993)A reference is made in 2.1(b) to “national legislation”. In South Africa this means theMines and Works Act, 1956 (Act No. 27 of 1956). Amdt 3 2.1(b)参考“国家法律”。

在南非指的是矿山工程法案,1956(法案号27,1956)。

Preface序言There is a need (caused by the growth of work forces that lack a common language) to standardize a system, that does not require the use of words, of giving information and cautionary warnings. 有必要进行体制标准化(因越来越多的劳动力缺乏通用语言),不必通过使用语言给出信息和警告。

Output of production is to a great extent dependent on the health of personnel. One factor that is essential to the maintenance of health and of a steady flow of work is the elimination of danger to personnel. 产量在很大程度上取决于人员的健康。

保持工作健康稳定的一个基本因素就是消除对人员的危险因素。

The use of colour identification as a means of speedy recognition and a warning of danger, is obviously a valuable contributing factor in the reduction of industrial accidents. However, in the case of accident prevention, other efficient and established safety measures should not be replaced by, but should be used in conjunction with colour identification. This code must, therefore, be regarded as supplementary to any regulations laid down for public safety. 使用色彩标识作为快速识别、警告危险的方法,很明显在减少工业事故中具有很大的作用。

但是,在事故预防中,其他有效的确立的安全措施不能被色彩标识代替,而应与色彩标识相结合使用。

因此,该法典必须被认为是已制定的公共安全条例的补充。

One essential factor of any such form of identification is that there should be uniformity of the colour schemes used in plants and organizations as this promotes greater safety, lessens the chance of error, and warns against hazards caused by the mishandling of materials. In the past, lack of uniformity has often been responsible for the destruction of property and injury to personnel. 这些识别形式的一个基本要素就是在车间和机构中使用的色系要具有统一性,因为这有助于更大的安全,减少失误几率,提醒因错误操作造成的危险因素。

在过去,没有统一性往往是造成财产破坏和人身伤害的原因。

It is, however, important to note that the number of colour identifications in the field of vision of workers should be kept to a minimum. This will avoid confusion and fatigue, and provide greater emphasis on the markings that are finally used. 但是,必须注意,在工作人员视野内的色彩标识的数目应保持在最小限度。

这样可以避免混淆和疲劳,更加突出所运用的标记。

The International Organization for Standardization (of which the Republic of South Africa is a member) has published recommendations regarding the use of colour codes, and the range and application of the colours given in this code are based on theserecommendations. 国际标准化组织(南非共和国是其中一员)已经出版了有关色彩代号运用的推荐规范,本规范中的色彩范围和应用是根据这些推荐规范。

Education is an essential part of any system for giving information. On premises where colour identification is adopted (whether it be for safety, identification, or informatory purposes), it is essential that a program of education be applied. Education programs should be competently administered, and should be of such a nature that no personnel are allowed to work in any area of a factory or industrial plant until they are fully conversant with all relevant colour codes. 教育是信息系统的必要部分。

采用色彩识别(为了安全,识别或提供信息)的一个前提条件就是实施一个教育课程。

教育课程应该由专业人员组织执行,应该保证在充分熟悉相关颜色代号之前,任何人不准进入工厂或工业厂房的任何区域。

Finally, it is felt that, by the adoption of the colour identifications given in this code, and by its acceptance and use on a national scale, work personnel and the country as a whole will benefit. 最后,通过采用本规范的色彩标识,在全国范围内认可和使用,将有益于工作人员和整个国家。
