Introduction

This document is a concise document on the data definition of light and lighting. It is also a basic data source generally accepted and recognized internationally. Any standard system can be introduced with modifications required. The problem of dosimetry of skin photobiology is based on the fact that ultraviolet radiation can cause erythema on human skin to a degree similar to The wavelength has a great relationship. between 250nm and 400nm, the degree spans 4 orders of magnitude. Therefore, it is believed that the ultraviolet radiation received by an individual The statement that the radiation dose is 1J·cm-2 (104J·m-2) cannot explain the results of radiation expressed as erythema. If the radiation source is purple If external fluorescent lamps are used, no erythema reaction will occur except for severe abnormal pathological photosensitivity reactions in humans. But by no means The same dose of radiation from a filtered mercury arc lamp or a fluorescent sun lamp will produce a distinct violet-red color in most people with fair skin. spot. Therefore, photobiologists have long recognized the need to express this amount of irradiation as an erythema-weighted parameter. In recent years, the term “minimum erythema dose” (MED) has been widely used as a unit of measure for erythema-causing radiation. due to minimal red Spot dose is not a standard measurement unit among all measurement units. It has different characteristics of individual sensitivity to ultraviolet radiation, so This dose of erythema is unreasonable. Variables that influence "minimum erythema dose" include the optical and radiometric properties of the radiation source, the amount of irradiation factors that determine location), as well as observational factors (e.g. end point determination, recording of time since irradiation and ambient illumination). To avoid continued misuse of the term “minimum erythemal dose”, it is recommended that this term be reserved only for observational studies in humans and other animals. term, and adopt the new term "standard erythema dose" (SED) as a standardized unit of measure for erythema-causing ultraviolet radiation. Erythema reference action spectrum and standard erythema dose

1 Scope

This document specifies the reference action spectrum ser (λ) and standard erythema dose (SED) that cause skin erythema.

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. Edition)

3 Terms and definitions

The terms and definitions defined in CIES017/E.2020 and the following apply to this document. For the purpose of standardization, ISO and IEC maintain a terminology database at the following address. 3.1 ser(λ) A function reflecting the spectral dependence of the ability of ultraviolet radiation (3.6) to produce just appreciable actinic erythema in human skin. [Source. CIES017/E.2020,17-26-065] 3.2 Erythemalirradiance The effective irradiance is obtained by spectrally weighting the spectral irradiance Eλ with the erythema spectral weighting function ser(λ) (3.1), in which the erythema spectrum plus The weight function ser(λ) is normalized to 1 at the maximum value. Note 1.This definition assumes that the actinic effect under consideration adopts an action spectrum with a maximum value of 1. Note 2.It is necessary to specify which actinic action spectrum is used, because the units of any action spectrum are the same. Note 3.Erythema irradiance is expressed in watts per square meter (W·m-2). [Source. CIES017/E.2020,17-26-067] 3.3 erythema dose erythemaldose Her Time integration of erythema irradiance (3.2). ......
