招标技术参数怎么写才可验证

结论：参数要有数值、有条件、有验证方式，三者缺一就难以客观评判

招标文件中的技术参数，最终要用于判断投标产品是否符合要求。如果参数写得无法验证，评标时就只能凭投标方的自我声明，客观性无从谈起。

一条可验证的参数应当包含三个要素：

数值要求。 具体的数值或范围，而不是定性描述。

测试条件。 在什么条件下达到这个数值。

验证方式。 用什么方法、提供什么证据来证明。

三者缺一，参数的可验证性就打折扣。 实务中最常见的缺失是第二项——只给数值不给条件。

常见的不可验证表述

定性词汇。 「结实耐用」「性能优良」「舒适」「操作简便」。这些无法判断符合与否。

无条件的数值。 「续航不低于 20 公里」——什么载重、什么路面、什么速度、什么温度？

无验证方式。 要求某个参数但不说明如何证明。

自相矛盾的要求。 比如同时要求很轻的重量和很高的承重，物理上难以兼顾。

指向性过强的参数。 参数组合只有某一款产品能满足，这在合规上有问题。

「无条件的数值」是最常见也最容易引发争议的问题。 不同厂家按不同条件标注，数值看起来差别很大，实际可能相当。

可验证的写法

以轮椅的几个常见参数为例：

参数	需要界定的条件
续航里程	载重、路面、速度、温度、电池状态
爬坡能力	载重、坡长、连续或瞬时、路面
整机重量	含不含电池、含不含配件、标准配置
折叠尺寸	是否拆脚踏、是否拆电池
最大载重	使用者体重还是含随身物品
座宽座深	测量部位与方式
制动距离	载重、速度、坡度、路面

写法示例的思路是： 参数名称 + 数值要求 + 测试条件 + 依据的标准或方法 + 需要提供的证据。

比如续航里程，可以写成：在规定载重、规定路面、规定速度、规定环境温度、电池满电状态下，连续行驶里程不低于某数值，提供具备相应资质的检测机构出具的报告。

这样写出来，投标方知道该提供什么，评标方知道该看什么。

条件的界定

界定条件时的考虑：

条件要贴近实际使用。 按实际使用场景设定，而不是按理想条件。

条件要可执行。 检测机构能按这个条件做测试。

条件要统一。 同一参数的条件对所有投标方一致。

条件要有依据。 尽量引用标准中规定的条件，这样各方理解一致。

「尽量引用标准中的条件」是实用的做法，因为标准中的测试条件是公认的，不必自己重新定义，也减少了理解分歧。

验证方式的约定

报告要求。 由谁出具、什么类型的报告、时效要求。

报告的覆盖。 报告要覆盖招标要求的哪些项目。

样品验证。 是否需要提供样机、是否做现场测试。

现场演示。 某些功能可以通过现场演示验证。

承诺函。 对于难以通过报告证明的内容。

「报告的覆盖」要写清楚。 只要求「提供检测报告」是不够的，因为报告可能只覆盖部分项目。建议列出必须有报告支撑的参数清单。

参数的合理性

设定参数时还要考虑合理性：

是否必要。 每条参数对应实际需求，而不是照搬别人的模板。

是否可达。 市场上有产品能满足，且不止一家。

是否矛盾。 参数之间不存在物理上的冲突。

权重是否合理。 关键参数与次要参数的区分。

建议在定稿前做一次市场调研，确认设定的参数组合有多家产品能满足。只有一家能满足的参数组合，在合规上是有问题的。

应当纳入的参数

轮椅采购中值得关注但常被遗漏的参数：

耐久相关。 疲劳试验后的状态，反映长期可靠性。

阻燃。 面料与坐垫的燃烧性能。

生物相容性。 接触皮肤部件。

防护等级。 电动产品的防水防尘。

可维护性。 易损件能否单独更换、备件供应承诺。

售后条款。 保修期、响应时间、备件供应期限。

「耐久相关参数」在采购中很有价值，因为它区分的是长期使用的可靠性，而多数招标只看新品的性能参数。

评标时的核对

有了可验证的参数，评标时的核对就有依据：

逐条对照。 每条参数对应投标文件的哪一页、哪份报告。

核对条件。 报告中的测试条件与招标要求是否一致。

核对型号。 报告覆盖的型号与投标型号是否相同。

核对时效。 报告是否在要求的时效内。

核对机构。 出具机构的资质是否符合要求。

建议做一张核对表，每条参数一行，记录对应的证据位置和核对结论。这张表也是评标记录的一部分。

参数之外的要求

招标文件中除技术参数外，还值得明确的内容：

资质要求。 投标方和产品的资质证明。

报告要求。 前面说过的覆盖、时效、机构要求。

售后要求。 保修期、响应时间、备件供应期限、培训。

交付要求。 时间、地点、验收方式。

变更处理。 供货期内产品变更的通知义务。

「供货期内的产品变更通知」在长期供货合同中值得约定，因为供应商可能在合同期内更换材料或改进设计，而采购方需要知道交付的是否仍是投标时的产品。

常见的争议点

评标和履约中容易产生争议的：参数条件的理解分歧；报告覆盖范围的认定；配置差异的处理；以及实测值与标称值的偏差如何判定。

这几项如果在招标文件中就写清楚，能避免大部分争议。

我们的做法

如果采购方在拟定技术参数时需要技术层面的参考，我们可以就参数的可验证性提供意见——哪些参数需要界定条件、条件怎么设定、需要什么样的报告支撑。

对于投标方，我们可以按招标要求的条件安排测试，使出具的报告能直接对应招标参数，避免出现「有报告但条件对不上」的情况。

Conclusion. Technical parameters in a tender document ultimately determine whether a bid product meets requirements. Written so that they cannot be verified, evaluation rests on the bidder's own assertion and objectivity disappears. A verifiable parameter carries three elements: a numerical requirement, meaning a specific value or range rather than a qualitative description; test conditions, stating under what conditions that value is achieved; and a verification method, stating what method and what evidence will demonstrate it. Missing any one weakens verifiability, and the element most often missing in practice is the second: a value with no conditions.

Common unverifiable wording. Qualitative terms such as robust, high performance, comfortable or easy to operate cannot be judged as met or unmet. Values without conditions, such as range not less than twenty kilometres, leave the load, surface, speed and temperature unstated. Requirements without a verification method specify a parameter without saying how it is to be demonstrated. Self-contradictory requirements demand, for instance, very low mass together with very high load capacity, which is physically difficult to reconcile. And overly directive parameters produce a combination only one product can satisfy, which raises compliance problems. Values without conditions cause the most disputes: manufacturers state figures under different conditions, and numbers that look very different may in fact be comparable.

Writing them verifiably. For common wheelchair parameters, the conditions needing definition are as follows. Range needs load, surface, speed, temperature and battery state. Gradient capability needs load, ramp length, whether sustained or momentary, and surface. Mass needs whether battery and accessories are included and what constitutes standard configuration. Folded dimensions need whether footplates and battery are removed. Maximum load needs whether it covers the user alone or includes carried items. Seat width and depth need the measurement location and method. And braking distance needs load, speed, gradient and surface. The pattern is parameter name plus numerical requirement plus test conditions plus the standard or method relied upon plus the evidence required. Range, for instance, can be written as continuous travel of not less than a stated distance at a specified load, on a specified surface, at a specified speed, at a specified ambient temperature, from a fully charged battery, supported by a report from an appropriately accredited laboratory. Written that way, bidders know what to supply and evaluators know what to examine.

Defining conditions. Conditions should be close to actual use rather than idealised. They must be executable, meaning a laboratory can test to them. They must be uniform, applying identically to all bidders. And they should have a basis, ideally citing conditions specified in standards so that all parties understand them the same way. Citing standard conditions is practical, since they are commonly recognised, need no fresh definition and reduce differences of interpretation.

Specifying verification. Define report requirements covering who issues them, what type and what currency. Define report coverage, meaning which of the tender's items must be covered. Define sample verification, meaning whether a demonstration unit is required and whether on-site testing will occur. Define demonstrations, since some functions can be verified by showing them. And define undertakings, for content difficult to evidence by report. State report coverage clearly: requiring test reports alone is insufficient, since a report may cover only some items. List the parameters that must be report-supported.

Reasonableness of parameters. Consider whether each is necessary, corresponding to a genuine need rather than copied from a template. Consider whether each is achievable, with products on the market meeting it and more than one supplier. Consider whether they conflict physically. And consider whether weighting is sensible, distinguishing key from secondary parameters. Survey the market before finalising to confirm that several products can meet the combination: a combination only one product satisfies raises compliance problems.

Parameters worth including. Often overlooked in wheelchair procurement are durability measures, covering condition after fatigue testing and reflecting long-term reliability; flammability of upholstery and cushions; biocompatibility of skin-contacting components; ingress protection ratings for powered products; maintainability, covering whether wear parts are separately replaceable and what spare parts supply is undertaken; and after-sales terms, covering warranty, response time and the period for which spares will be available. Durability measures are particularly valuable in procurement because they discriminate on long-term reliability, whereas most tenders examine new-product performance only.

Checking at evaluation. With verifiable parameters, evaluation has a basis. Check item by item, identifying which page and which report supports each parameter. Check conditions, confirming that the report's test conditions match the tender's. Check models, confirming that the report covers the model bid. Check currency, confirming the report is within the required period. And check the laboratory's accreditation against requirements. Produce a checking table with one row per parameter recording the evidence location and the conclusion; that table also forms part of the evaluation record.

How we handle it. Where a purchaser needs technical input when drafting parameters, we can advise on verifiability: which parameters need conditions defined, how to set them and what kind of report supports them. For bidders we can arrange testing to the tender's conditions so that the resulting report corresponds directly to the tendered parameters, avoiding the situation of holding a report whose conditions do not match.
