Preface: This standard modified adopt international standards ISO17166:1999 / CIES007 / E 1998 "standard of erythema effect reference spectrum and erythema dose". This standard of ISO17166:1999 part of repetition in the text of the text and the formula of individual is not easy to understand for the appropriate revision. In the reserved ISO171 All terms, definitions and explanations, 66-1999, on the basis of the standard reference to the world health organization, the world meteorological organization, the UN environment programme (unep) and the international the radiation protection commission jointly issued the uv index: practical guide , defines the scope of the wavelength of ultraviolet radiation, and the uv refers to the guidelines Several calculation methods into the provisions of this national standard. This standard will be a 66-1999 and the international organization for standardization rules of ultraviolet radiation wavelengths, uv index calculation method is introduced into the national standards system, is conducive to the promotion of the measured data of the ultraviolet radiation in China and the international comparability of ultraviolet radiation forecast service products. This standard and ISO17 Differences in 166-1999 details are as follows: a) since ISO17166:1999 equivalent adopts CIES007 / E 1998, so in addition to the ISO in the original preface, also includes preface and introduction of CIE, this part has quite a lot of repetition, and contains some of the technical specification, Nearly a third of the original length. All out, obviously is not appropriate, but if keeping all encumbrance, and consistent with the writing requirements of national standards in China is not. All this part of this standard in the introduction of this standard, and delete the repeated and has nothing to do with the technical regulations of part of the text. B) in ISO17166 The textual Erythemareferenceactionspectrum and Erythemaactionspectrum, corresponding to this standard in the uv erythema effect reference spectrum and erythema effect spectrum. Here, the term uv erythema effect in the front of the reference spectrum with 2 words, is In order to more clearly the effect of spectrum and ultraviolet radiation corresponding relations. Therefore, in the English title of this standard is also called UV. In order to better distinguish between the two, this standard reference spectrum uv erythema effect of symbols (Li er (lambda)) with capital, in order to show and erythema effect spectrum ( er (lambda)). C) of this standard are given Article 11 terms and their definitions, including six from ISO17166, the remaining 5 from the uv index: a practical guide in . D) ISO17166 in fourth and fifth paragraphs respectively presents the definition of the term and for further description and explanation of the term. Between these two not only have more repeat, but also differ Write the requirements of national standard in our country. For this purpose, the editorial committee will be the fourth and fifth paragraphs of the original content to merge, delete duplicate each other in the original text, excess will those unfavorable as defined in the original text is given as the annotation. E) the original ISO17166 4 section (3.4) corresponds to the standard of minimal erythema dose (MED) of the definition of expression do not conform to the requirements of the narrative of national standard in our country, therefore this standard and defining words, and defines the original as the annotation. F) ISO17166 4 in the original period of (3.4) corresponds to the standard of minimal erythema dose (MED) in the exposure of observation time interval, the only mention of typical Time interval of 24 h, according to our country the skin experts, generally the time interval of 24 h + 2 h, so clearly shows the change of scope of this standard. G) ISO17166 5.1 in the original type (2) (corresponding to the standard type (8)), from the perspective of dimension is clearly false. We understand the original text Under the condition of culvert, the proper revision. H) ISO17166 5.3 in the original note on skin type, the original type for Ⅰ to Ⅳ type. According to our experts, skin is now widely used in international Ⅰ to Ⅵ, this standard has made the corresponding revision accordingly. I) in order to make more practical, this standard reference The world health organization (who), the world meteorological organization, the United Nations environment program and the international commission on non-ionizing radiation protection jointly released by the UV index: practical guide rules in , the UV , UV B and UV C band made clear by the standard of definition, therefore increased by 3.7, 3.8, 3.9 of this standard Such as 3 definition; Also with reference to the practical guide  to the current information about release ultraviolet radiation in the international general uv index calculation method and according to index of uv exposure level made the rules, such as increased 3.10, 3.11, two corresponding definitions and chapter 6, 7. J) to facilitate users to better understand the ultraviolet radiation The harm of human body function and protection, the standard also is given in annex A related introduction. Appendix A of this standard for informative appendices. This standard put forward by the China meteorological administration. This standard by the China meteorological administration under centralized. By the China academy of meteorological sciences is responsible for the drafting of this standard, Beijing normal university, the Chinese people's liberation army air force general hospital to participate Add draft. Main drafter of this standard: Shang Jie, bing-zhong wang, Zhang Baozhou, liu wei. This standard is published for the first time.
Description:This standard stimulates the effect of uv erythema reference spectrum and the standard of erythema dose, ultraviolet radiation wavelength range, uv index, such as exposure level terms and related content.
this standard applies to the erythema dose measurement and its result of expression, application and ultraviolet index released, etc.
